A month ago I changed engine oil, oil filter and both fuel filters. All replacement filters are Motorcraft and my mileage is off a solid 2 mpg after the fuel filter replacement.
View 14 RepliesHow many miles should I go before changing fuel filters and air filter?
View 14 Replies2013 6.7 F350 13,500 miles... Changed the fuel filters and got them bled out and truck runs OK but have a whining noise from the engine compartment fuel filter area.
View 14 RepliesIve had my 2011 for 20 months. I have 7,300 miles. I know the manual states changing around 22k but do you think time is a factor as well? I wont hit 22k for two years. Truck will be 3.5 yrs old. Should I just change them at 10k and see how they look? Don't want to waste the money either if its unnecessary. I use it 50/50 towing/unloaded.
View 8 RepliesChanged the fuel filters. No issues in replacing.
Primed them by the book - key on 30 seconds 6 times
Now I have low pressure warning and reduced power.
All parts were FOMOCO...
I changed both fuel filters on my 2015 F350 6.7 I turn the key online for 30 seconds then turned it off for total of 6 times when to start the truck this morning after driving it yesterday and it took a little bit longer to turn over before it finally did, did I miss something up that I do something wrong. So I let my truck warm up this morning after going to start it at took a little bit longer for it to turn over I turned it off wait a few seconds then turned it back on and she started up how she used to perfectly fine does it just need to go through a drive cycle. This is the second fuel filter replacement nothing was wrong with the other ones I'm at 40000 miles now ... also it seems like the fuel filter on the frame rail is louder if you put the filter in upside down on that will it fit stupid question I'm sure I did it right but thought I'd ask before I tear it apart....
View 14 Replies2011 F250 6.7 Had the fuel filters changed by the dealer today. No noticeable sounds when I left the dealership, & no fuel stops on the way home (120 miles one way). When I got home, before shutting off the truck, I heard a loud groaning/singing from inside the truck. With the truck still running, I get out, & the groaning/singing is very pronounced....never heard this before & appears to be emanating from the fuel filter underneath the truck.
I turned the truck off, then turned the key back to the position that the fuel pump turns on, and wow, the pump is very loud. Definitely something going on because when I turn the key for the pump to turn on but not start the truck, I can feel the vibrations of the pump working from inside the truck and when listening from underneath the truck, it is very loud. Before today, the truck never made this noise and never heard the pump before.
I just bought my first diesel truck back in November. It's a 2005 F-250 with the 6.0L and the 5 spd torq-shift automatic tranny. Last weekend I drove the truck to South Carolina, about a 600 mile round trip from where I live. On the trip the truck only got 13 mpg! I wasn't towing a trailer and the truck was empty except for me and my suitcase. It's not loaded up with mods or anything, it's completely stock power wise.
I'm extremely disappointing, especially since a friend of mine has a 2006 F-250 identical to mine and he gets up to 21 mpg on his. What can be done to improve my mileage? I'm not a lead-footed driver, and the trip was done with almost all interstate and highway driving, very little driving on back roads or stop and go. If this is the best the truck will get, I'm going to sell it and buy a F-150!
Couple weeks ago fuel tank started coming apart clogged all filters. Replaced tank filters and fuel pump and blew out all of lines. Started and ran fine. Stays plugged in over night but now it'll crank but wont start. No codes showing up or anything...
View 1 Repliesjust picked up a 2012 F-250 6.7 XLT. I won't be driving the truck too often, probably no more than 5000 miles a year, and was wondering how long can oil last time wise. I would wait for the change oil indicator to come on, but was wondering if it's takes a year or so or what. Was probably thinking changing it out once a year regardless of low mileage. I have the service plan from my dealer for 3 years which they threw in but it's for 7500 mile intervals so maybe I can work something out with them. Def love the truck and now I hate having to drive my other vehicle as dailys.
View 9 RepliesOwn a 2011 6.7 diesel, 59K mileage, short bed 4 WD. Was driving at 70 mph and noticed my instant mileage display read 0. Usually I see a instant mileage reading of at least 16. No regen was in progress. Steady gas throttle. Display could be changed to other screens. After a few minutes it came back. But it jumped to 16 and did not ramp up.
View 3 RepliesI have read many different threads regarding the TPS sensor on the pedal and EBPV deletes on the E99 7.3L Powerstrokes. I am trying to troubleshoot some issues with my E99 7.3L. Usually on cool mornings and after not being started for awhile the truck will seem to be stuck in an Idle. This is an intermittent problem that doesn't always happen.
I cleaned the connections to the Tps and the IVS sensor and put them back in. No luck. On another note I am also seeing a reduction in fuel mileage and power like the truck is being restricted. I don't know if these symptoms are related or possibly their own issues. I am troubleshooting and possibly thinking it is the EBPV system that isn't working correctly. Considering doing an EBPV delete with a NON-EBPV Pedestal and Flange.
My7.3 is idling rough till I pull the fuse for the fuel pump them it will smoothen out I ran a by pass switch to us my truck but the fuel mileage is bad why
View 13 RepliesI've been told that manually unlocking the front hubs on my '15 F350 dually, might just improve milage. Any concerns about the axle lubrication from being unlocked for extended periods of time? I rarely need the 4WD.
View 9 RepliesSo, 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?
I have a 2005 Prius that I bought about 1 year ago that has about 75k miles. According to the display, I have been getting about 5.5l/100km (~43mpg) up until I did some maintenance in July.
A friend changed the oil, oil filter, and cabin air filter. Also, right around this time I bought a new set of tires. For some stupid reason, I had the idea that it had run flat tires, so that's what I bought & by the time I realized my mistake, it was too late.
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????
View 14 RepliesI have a 2006 F250 c/c LB and I am curious, how much fuel is left in the tank when the low fuel light comes on?
View 8 RepliesFor the last four months my 04 F350 has been having the same problem every now and then. Cruising down the highway at a decent speed and the fuel pedal/fuel shuts off. Only lasts seconds then re-engages. Two lights come on. Low fuel and water in fuel. I changed the internal fuel pump last week and it did it again tonight. The truck runs great otherwise except for an occasional death shake while stopped at a light. No codes came up and FICM is at 54.
View 14 RepliesChanged fuel filters today. Now my water in fuel light is coming on. But the truck is not running any different no sputtering or anything. ????? Could this be human error
View 14 RepliesI 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.
