Uh oh...the fuel filter
 

Hi All,

My 2008HD has terrible power loss on hard acceleration. The fuel filter has 0% life left. The truck only has 1400miles on it. I am wondering if: A. the truck sat on the dealers lot for several month...accumulation of water/grime in fuel system, and/or B. the weather here has been cold, can that affect the filter? In any case, seems pretty weak to have to replace the filter only after 1400 miles. My old Ford 250 would go 15000 before I would change it. Anyone else experience this?

Thanks

gelling during cold temps will always take place in the filter first.....change er out but

Yeah define cold. Maybe the dealer put bio in it? I'd bet gelled fuel like Whit said but maybe they put some nasty fuel in it too.

I have changed the fuel filter on my trucks at first 1,000 miles just because in the past. I bet the boys above me are correct about gelling. Unless cold means 40, and in that case gelling is not a concern.

Brrr cold. In the zeros and teens. Anything to prevent gelling? How often does everyone else change out their filters? Thanks!

Blend of #1 and #2 fuel, at least 50/50 to -20, 75/25 to 100% #1 for anything colder. If your gelled up, Power Service 911 in the tank and change out the filter. Next chance you get, top off her with #1.:U:

You can grab some Power Service 911. Fill up the new fuel filter with it and pour the rest in your tank.

You're at the perfect temps to be gelling so I'd look in that direction.

You should be getting 10-15K out of your filters.

About every 10k. That's one thing you can't replace enough. Cheap insurance. :U:

I am finding that My 08 doesn't seem to like to go as long as my 05. When I hit 40-50 % I change out the filter. Both trucks had power adders. One time when on route home I believe it was -37c (40 is 40 on both scales lol) I had conditioner but it still started to gel ,It went from 50% to zero under throttle then said change filter now. It didn't go into full limp but if i hit the throttle hard it would reflash on the DIC, and RPMS would start to fall off. Lucky I only had 20 miles to get to a GM dealer, I had a filter on board but not my kinda fun changing that out on the highway lol. And some of this fuel nowadays, I always try to fuel up at a busy station, some of these hillbilly stations in the country have fuel that sits for a lot longer..

Doesn't the fuel filter life go off mileage like the older trucks? On them it has no real way of knowing when you need to change the filter.
