Ford 6.7L Power Stroke Diesel :: Fuel Filter / Pump Started Squealing And Making Vibrating Noise
Jan 13, 2016
Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I figured 200 dollars cheaper than taking to ford....
I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good.

I have an isspro gauge and did the blue spring about 5 years ago. Since then my fuel pressure is in the 65psi range.
Last week it dropped to 50-55 normal driving and I figured the HFCM was on it's way out (195,000 miles). Replaced the HFCM and the pressure was a bit higher, but not back to it's usual range. Then pulling the boat home from the lake a couple days ago, I saw it at 45psi. On a couple hills it went as low as 40 psi, so I was getting gripped...coasting downhill it only went back up to 50 psi and no higher. Got 'er home and currently not driving it.
In garage with Key On Engine Off, during injector buzz, I can hear a hissing/air noise at the upper filter bowl. Also, the bowl drains empty once the pump cuts off and the sound of air stops too.
I am hoping it's a regulator issue, but I don't know if they are known to wear out or go bad, or if something else in the upper filter housing went bad. So I ordered a new upper fuel filter housing which also has the oil filter tower attached and I'm assuming that these new units would come with the blue spring upgrade already done.
I can check for codes tomorrow when I bring my computer home from work, so I haven't checked for codes yet. I pick up the new filter housing tomorrow and will periodically check back here during the day tomorrow.
Also, while I'm at it: the new HFCM doesn't have the heater. Can I just leave the old connector from the harness un-connected to anything?

I am a new diesel owner. I bought a 2014 F250 about 9 months ago. Three times in the last 50k miles I have heard the fuel pump near the tank making noise. Twice, while making the high pitched noise I have gotten a low fuel pressure warning and reduced engine power.
The first time, I left the truck with the dealer for two days while a tech drove it around. everything checked out fine. (30k miles)
The second time I heard the noise i did not get the low fuel pressure warning. (40k miles)
Today, I heard the noise and got the lower fuel pressure warning just before the truck stalled out. Lucky for me, I was near home. After a minute the truck start and I nursed it the last mile or two. (56k miles)
The tow truck just picked it up and is off to the dealer. It sound to me like the low pressure transfer pump is bad or going bad.

So, on my way home from checking out a house all of a sudden the truck started vibrating when getting on the highway. Then it got worse quickly. So I pulled off at the next exit and pulled into a parking lot, the truck shuddering badly any time I pressed the fuel pedal. Had it towed to my local Ford dealer. I'm thinking torque converter/transmission, but I freely admit I don't know. Here's what I think is pertinent info-
1. I bought it at 84k miles, now 122k. Oil changed every 5k, fuel filters every 10k, coolant every 20k, trans fluid every 20k. Don't kmow what was done first 84k miles before I bought it.
2. Driveshaft rebuilt one year ago. Both fr and rr diff fluids changed a few months ago, along with transfer case fluid.
3. When in park or neutral engine revs perfectly smooth. When placed in gear and fuel is added it starts to shudder, getting worse as revs go up. Does not vary with road speed, only with engine speed and load into transmission.
4. There are no codes at all. All temps were normal. Engine oil and trans fluid level normal.
5. A few months ago when coming home from a trip I suddenly had the same symptoms about 3 miles from home, but not as bad as today. Made it home taking it easy and went to bed. I was exhausted from a long day of driving and when I test drove the truck the next morning to check it out it was smooth as could be, so I thought maybe I imagined it. Symptoms did not reappear until today, a few months and several thousand miles later.

I've got an issue with my truck, I was towing home my camper this weekend and my engine started missing out and vibrating very bad, then it overheated... pulled over and check codes, p0263, p0299, p0300, p0301. Oil all over engine, tons of blow by, definitely a dead miss on cylinder 1. Smokes bad out of exhaust, zero power, and blows cap off of oil filler when loose, tons of smoke and oil from ccv.
My question is, could it be in the valve train? Or is it going to lie in the piston/rings? Blown head gasket? It did overheat, but didn't puke out of bottle, turbo timer kept it running for a bit after I shut it down roadside, egts were definitely high. Also the egr is deleted, have a predator programmer with custom tune for she delete.

I have a very slow fuel drip off the housing for the fuel filter on the engine. Can't see where it's coming from. It started sometime after I changed the filter a couple of months ago.

So, I just had the fuel pump replaced on my '15 6.7 a month ago and it just died again. (next day edit: it didn't actually die, it showed all the same symptoms)
Same symptoms: whining sound, low fuel pressure warning, reduced power warning.
This time I'm 50 miles from home so I pulled off the road before it shut off. Interesting, I was in a hilly area and my low fuel warning came on too. We are waiting for a tow. I was considering trying to push on but don't want to get stuck in a dangerous spot on the highway. We're in a church parking lot.
So, last time this happened I was on flat road with about a half tank of fuel on a lunch break. I ran a mile after the warnings came on to feel out the issue and to see what would happen. I happened to be only about a mile away from my dealer so I drove that way. I got reduced power warning and then it cut power on me (limp mode). I made it to about 100 yards away before it cut off.
This time, I was in a hilly area at night on a windy two lane road with no shoulders in the woods. I was miles from civilization and was showing below a quarter tank of fuel. ~100 miles to EMPTY. I got the low fuel pressure warning first and then the reduced power mode before the whining noise started. I was climbing a hill on a curve at the time. I drove a quarter mile and then pulled off the road into a parking lot so I wouldn't be stuck on the shoulder. It didn't actually go into limp mode.
I let it sit a few minutes, talked it over with the wife and decided to call for a tow. After talking to the tow truck driver who said he would be an hour because he had to go find a bigger truck, I decided to see what I could do while I wait. I fired it back up and the fuel level dropped to below 1/8 and I was now showing 33 miles to EMPTY. I was parked on a hill with the back end up. I had backed the truck into a space to make it easier for the tow truck driver. I let it run a minute, checked for leaks and it seemed to run fine with no studdering or additional warning lights.
CEL was on but no new warnings. I put in my code reader and pulled the P0087. Just one code. I revved it a bit to see if there were any issues. It seemed fine so I decided to try my luck. I started driving towards home with the intention to stop at the first diesel station to fill up. Truck ran fine. After two minutes of driving gently, heart racing, my fuel level came back up and it now read 88 miles to EMPTY. I drove 11 miles to the nearest station and filled up. No issues. I shut it down. I fired it back up. Still no issues so with a full tank, I drove home the remaining 30 miles without issue.
Planning to take it in to the dealer Monday to get it checked. Could this be from an air pocked due to low fuel level and hilly terrain? Is my new pump dying already? Is there something else going on inside the tank or elsewhere?

Well I finally had time to change out my composite oil pan to the metal one. Nothing was wrong with the old one but Ive seen the composite pans get hit by a rock and crack so I decide to get the metal one. It didnt take long once I had the oil drained and its very easy to get to. Once i had the old pan off I did find two piece of sludge stuck to the oil pickup screen, they had a sliver of aluminum in them. My oil reports have been coming back with high aluminum content so I am not really sure what to think being my motor had 33k miles on it now.
I also changed out the fuel filter and when I dropped the frame mounted filter I found about a teaspoon of rust in it. I'm not one to run my truck down to E but I admit I did so twice since the last filter change. Since I found the fuel filter kit for 60 buck(ford dealer wanted $140) I think I will move my fuel filter changes to 10k miles instead of 15k. Last but not least I also added SPE 6.7 Full Lock Diff Kit which allows the locked rear end to stay engaged past 20 mph. It was a simple 10 min installation with just a few wires and easy directions to follow

While driving from SD to Chicago today 2 warnings popped up at the same time saying to change the oil and fuel filters. Had both done 2500 miles ago. Am I right that the Dealer just didn't reset these? I thought these were measured by miles and driving habits.

My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

I have my aux fuel tank pump hooked to upfitter 3. It has worked perfectly until this week. I started to transfer fuel and the aux fuel gauge and fuel pump both quit. The led on upfitter switch 3 still illuminates, but no fuel pump. I found fuse 9 on passengers kick panel is for upfitter 3. The fuse was good. Is there another fuse somewhere for the circuit I've missed? I can trouble shoot the wiring if necessary, but it's tough to do all behind the left side underbed box and not easy to get to. I've missed something simple before I go further????

I was going to change the fuel filter on my truck yesterday, but couldn't figure out how the guard comes off. It has a bolt but it also has a rivet in it and looks like its all one piece so Id have to drill the rivet to remove. I tried to just spin the housing off.

While I was changing the oil yesterday, I also changed the fuel filters. The primary filter had some debris that was confirmed by a magnet to be metal. I have seen a little bit of this all three times I have changed the filters. The filter itself is very clean, but there remains a small amount of metal slightly more coarse than filings.
I don't really have any concerns that it could be coming from the HPFP because that is after the secondary filter and would not be returned to the tank. Also anything from the HPFP would have fouled several injectors by now. I don't even think there is any iron in the pump.
I guess it could be useful to put a magnet in the water separator reservoir, but I don't even know what good that would do since the debris is large enough that it is being caught by the filter and of course the secondary filter is even less microns. It would just be nice to know where in the world this stuff comes from.

Noticed change in power after changing the fuel filters on 6.7 .... Seems like it has a fuel restriction at times maybe even air somewhere in the line. Thought I felt the truck hesitate after hitting the gas and Cavitating when I hit the gas petal. Both new filters are motorcraft parts. I did follow the procedure after installing filters by turning the key on 6 times waiting 30 seconds in between. Could it be a problem with the fuel pump. I should say I didn't have this until I changed the primary filter.

Changed my filters and this was in the bottom of the filter housing. I looked on the pleats and down in the center didn't find anything. Went to two Ford diesel techs one said is was the hpfp and should do the the whole fuel system. The other said if the hpfp was coming apart the shaving would not be in the bottom of bowl and to check the filter again in 5k miles. No check engine light, drives great, no other problems.

Replaced both fuel filters same as usual. Cranked right up and I let her run while I put up the tools and look for leaks. Notice it started running rough, so I jumped in and started to back out of carport and it went dead. Ran battery down and it won't hit a lick. Replacement (racor) filter same as last few changes. Running just fine before change so it has to be something simple, but what?

I'm dripping fuel on top of the engine at the fuel filter . Where the line ties into the filter canister , there is a small plate that's attached with small Allen screws its dripping between this plate and the canister .... I assume there is a gasket/oring that is causing it ...... What is the part number or correct description so I can go to ford dealer and get one.
