Ford Super Duty (1999-2016) :: Low Fuel Pressure - Engine Power Reduced After Fuel Filter Change?
Feb 13, 2016
I had my fuel filters changed at the dealership today on my '15, and then I bought fuel and headed home (70 miles). About half way home I got a "Low Fuel Pressure" message and a little while after that "Reduced Engine Power" along with the check engine light.
I pulled over to see if they did something like leave the drain open, thinking it might be sucking air. Of course it was dark and I could not see anything. However I did hear a buzzing sound and could feel a vibration when I touched the fuel line going into the top of engine filter.
While it is possible I got bad fuel, I suspect they did something wrong installing the filters. Even after cycling the fuel pump multiple times they had a hard time getting it started afterwards; I think they finally disconnected the top fuel line to bleed the air out.
I continued home and made it, but not sure what to do now; its 70 miles back to the dealer.
What is the most likely problem? Improper fuel filter installation or bad fuel?
Should I pull the filters in the morning see if there is something obvious like an out-of-place gasket? If so, top or bottom filter?
Is this a tow truck affair or should I drive 70 miles back to the dealer?
What the heck is the buzzing sound?

2 nights ago changed the fuel filters for the 3rd time on truck since bought it a year ago. It has 67,000 miles. F350 6.4 L 2008. The truck ran for about 2 minutes and then wouldn't start. For the last two nights have done everything including cycling the key over and over to purge air, replacing the fuel filters thinking the first ones may have been defective, pumped the gas pedal while trying to start it, tried to start it with fuel cut off switch held in, changed o rings etc. The first night I didn't get fuel at the head but after changing the filters a second time, I now have fuel at the head. That is the only progress I have made. The truck has gas and it is fine as we are using it in other trucks. The battery has never been allowed to totally deplete.

Changing a fuel pressure regulator on one of these? I'm having an issue with it running really lean, like laying down with no power lean.I put the pressure gauge on it and I'm running an even 30 pounds at the rail. Changed the filter in hopes, but no change. Just changed the O2 sensors and they were both white.

I have an 2005 F250 4.2tdi XLT. There is a buzzing sound coming from somewhere near the fuel filter area in the engine bay. This started after changing the fuel filter during a service. Its also difficult to start now. It has to swing for 10 secs before the engine fires. What it could be?

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?

How often in miles (mostly highway and city) would you change the following:
1.Baldwin spin on fuel filter added with hutch mod
2. Napa diy 6637 air filter mod with no sleeve over it, just the paper element
3. Stock fuel bowl filter after having added a pre-filter (previously mentioned in #1)

I just had my first fuel filter change (about 9,000 miles). After the shop changed both fuel filters with factory Ford ones, a check engine light came on and a "low fuel pressure" warning, along with a "reduced engine power" warning. It also stalls a lot and takes a long time to restart.
Obviously, they didn't do it right. I suppose there is air in the lines or something didn't go back together correctly.
My '06 seemed to purge itself, but this truck obviously won't. It is not even driveable to get it back to the station, to see if they can correct the problem.
The thing is, I watched them do it, so if someone can ask me the right questions as far as what I saw, maybe I can lick the issue in the driveway myself.

We have been having near zero temps for several days and it occurred to me that there may be some amount of water in the water separator in the rail mounted fuel filter (not enough to send a message, but maybe some amount). I only have 3,000 miles on the truck. So, just wondering if a small amount of water is going to hurt anything in the filter or filter housing if it freezes? Should I drain the filter in freezing weather even though enough water hasn't collected enough to activate a message?

Changing tranny fluid/filter today, all has been going great until I went to take the filter o-ring out that didn't come with the filter. It will not come out! made a hook tool out of an old tooth brush like someone on here did, o-ring wont budge. Tried a hook pick, it wont dudge (actually bent the tip on the pick and started to tear the o-ring). Everything is ready to go back together and get filled, but this stupid o-ring will not come out!

I have a 2000 f250 V10 CC 4x4 long bed. The rubber fuel line that has a quick disconnect to attach to the fuel filter along frame is leaking. This is on the filter side going to engine. Ford tells me fuel line not available. Dorman products tech assist can't tell me which connector of there's will fit my truck.

I'm gonna change plugs , hoses, belts and fuel filter on my 08V10. Hoping it works with the mpg.
Anything else I should look for or do? Is there anything I need to know about changing the fuel filter?

My truck gave me low fuel pressure and reduced pressure limp mode at 21,000 miles. The fuel and air filters were changed at 16,000. The dealer said all they found was the fuel filters (at 21,000) were what needed to be changed. Also, why does my truck hum??

On my 05 Super Duty, the gauge light for the fuel and oil pressure are out. The needles are still illuminated red but the backlight for the gauges are dark. Are these replaceable bulbs or are they a circuit board diode or something that can't be easily replaced?

1999 F250 7.3 240k miles .... This is the second truck to act like this on me after I cleaned the in tank filters.
I had to cut the fpr spring to 30lbs for the truck to start fine cold and idle ok but has no power. When hot it wants to die and or dies at idle and has next to no power. ( I'm guessing from lack of fuel) but it's the only way for me to use it. With a new spring and 60ish lbs of fuel pressure, they won't even start.
I cleaned the in tank filters. New fuel filter. new oil. rebuilt the ipr. unplugged the ipc. no loss of boost. checked my uvch, wiggled all harnesses with no difference. I also tried dropping the tank again in case I pinched the return line but that made no difference.
I'm guessing that I need new injectors. I'm not close to anyone with a computer nor can I afford to throw away any more money at the moment.
Totally stumped and cannot seem to find a definitive answer online so far. Both trucks ran somewhat ok before and got worst once I dropped the tank and cleaned the filters which increased the fuel pressure. This is my second truck to act this way.

2003 F250SD 5.4 4x4... When I recently heard a growling coming from my front end. I read some great posts on here about the whole front end tear down. Replaced all my ball joints, universals, wheel bearing hub units, locking hubs.....
So yesterday i came home from work, about 30 minutes later i hit the key on the truck and it wouldn't start. Kinda sounded like it wanted to but was starving for fuel. SO i grabbed the fuel pressure gauge and did a quick check......and No fuel pressure at all. Checked the fuse, Couldn't find a Relay in the fuse panel (Is there one for the fuel pump??). Anyway 4 hrs later the trucks starts right up like nothing is wrong.
Go figure, I'm 2 days away from my last payment ...now everything has to be going wrong.... Do these fuel pumps act up like that ??

I just picked up a 2012 F350 lariat with about 65 000 miles on it, and while driving home, it popped up with reduced engine power on my screen. Tried adding DEF fluid, seems to right up to the top already, no actual change in engine performance either. Also, no check engine light or service light on (wrench light)....never run across this before and am totally thrown off. Haven't taken to dealer yet...
