My truck to me has not run good in a month. Well today I changed the fuel filter for the first time ( 8,000 miles ). It is not I tell you my imagination but the throttle responce is better today than when I bought it. Truck is awesome now, I can even here the AFE air filter sucking once again. I can't explain how much a filter improved my power. Someone tell me they seen this before!
My truck was just starved for fuel thats why I could here the injectors knocking so much.

Thanks for this board, who could I say all this to if not for you guys.

 

It's not your imagination. Your truck will run much better with a clean fuel filter than a dirty one. I change mine on a regular schedule, and always see an improvement in performance, and mileage.

 

Make sure you drain the fuel bowl when you change the filter. There are also a lot of people, including diesel mechanics, that pour additive directly into the fuel bowl when they change the filter to help clean the injectors.

 

Started engine this Sunday morn just to here engine from a cold start. I am glad to say the cold start is so quiet compared to the old fuel filter start. I am just surprised at the difference a new filter makes. I am in love again with my truck.

Change that filter NOW, DON'T WAIT .

 

Thanks for the post Ford 2002 and all who replied. With 10,000 miles, I was going to wait till the 15,000 mark to change the filter but took your advice, changed it, and can't believe the improved performance and smoother, quieter, PSD.

Great to be a student here!

 

Is there a reason to drain the fuel bowl before changing the filter other than not getting fuel everywhere ?? I changed my filter awhile ago , and didnt drain the bowl and everythign seemed to work out fine ???

 

You drain the fuel bowl until you smell diesel fuel coming out. It gets any water out of the bowl. I drain the water out at each oil change and whenever I change the fuel filter.

 

Thanks for the tip..............

 

I'm fixin to change mine tonight. I use Stanadyne and was wondering, do you fill the fuel bowl all the way up with additive or just put a little bit in?

I poured in bottle of stanadyne.

 

I use Stanadyne at every fillup, and so far haven't needed to add any while changing the fuel filter. It wouldn't hurt to do it, but it might not be necessary, especially for you guys with the newer trucks. A couple of diesel techs I've spoken to use the "fill up the fuel bowl with Stanadyne" trick when there's a definite driveability issue.

 

I take it that Stanadyne is a brand of injector cleaner?

 

It's a fuel additive that contains a cleaner. In the winter I use Standyne lubricity formula to offset the winter diesel fuel. There are other additives that they offer as well.

 

Do you run this with every tank? Or every once in awhile?

 

I run it in every tank in the winter, but didn't run it last summer. I may go ahead and run it every tank, but I'll probably run it every 4 or 5 tanks this coming summer. It does make a difference in the winter though. My truck is very flaky in the cold without using it, but it starts right up if I'm using the additive. I'm usually pretty hesitant to run additives on any vehicle I own, but Stanadyne has proved to be a good thing in my opinion. I talked to a couple of truckers at a truck stop one day and they said they used it with every tank.
