check fuel filter light..full davco fuel/water separator

What filter are you using the smaller micron ones will fill faster buying fuel at some t/stops, Where are you fueling up?

 

Considering that the davco filter is about $10 at the dealer. I would change it and see what happens

 

If it's filling up, that indicates it's used up.

 

change both

 

$10 filter and a 5 minute job, why wouldn't you switch the filter? I have had filters plug up in as little as 1,000 milies after being relpaced due to dirty fuel. It should be changed every oil change at the very least.

 

And an injector problem wont throw a fuel filter code...not saying that it doesn't have an injector issue, but the fuel filter code wouldn't be a precursor for it.

 

What does your filter look like when its removed from filter housing? Are you getting water when you drain housing?
It sounds like dirty fuel and your rep is overlooking the obvious by assuming its your injectors.

 

my davco has filled with less than 200 miles plenty of times. other times will last 10,000 miles. I keep 4-5 spare filters at all times & I am home everyday. change your filter, keep changing until no longer needing to change. you have a fuel contaminate problem.

 

I had similiar problem,truck was losing power and shaking while accelerating.
Check fuel filter msg came on.
Dealer replaced injectors and cups under warranty.
Truck was ok for few days then problem came back plus truck has hard time starting.
Fuel filter filled up very fast,i had to change it after 5000 miles.
Took it to my mechanic and he replaced fuel filter housing.
Truck felt stronger ang fuel economy improved.
I went to speedco for oil change and now fuel filter is filling faster and truck seems to be losing power again.
Will take it to my mechanic again next weekend for check up.
