changed my fuel filter yesterday took about 5 mins and then about 45 mins to get her started again!!! i did not like the situation i was put in there!! next time ill get some diesel fuel and screen it myself and fill the canister and reinstal hopefully that will help alot! well i maid a few post a month or so ago about poor fuel milage in my truck so i was kind of learly to change it since guys were saying my lift pump might b bad but it worked just fine so i dont think that is a prob dont know thought? i have changed fuel filter and IAT sensor hopefully this will help it some more 10 mpg is very bad! but i did notice it feels like i have alot more power in changing the fuel filter i might b crazy but i could feel myself sinking into the seat abit more after a test drive or 3 ;D

 

If the fuel filter was restricting fuel flow, then yes you will have a bit more power. That is normal.<br>John<br>

 

How much did the 275s really add by the seat of the pants meter or a gain in speed up a long grade or hill in your 24 valve? Your sig doesnt say you have a box??? I am looking at doing the injectors.

 

Which truck did you change the fuel filter on? If it was the 99' then at least you LP is still working or you wouldn't have been able to start it at all.

 

well the 275 injectors helped some i could tell more at top end about 55 to 60 got some more go juice! nope no box yet if u r going to run a box i would get bigger injectors than 275! trust me on that one the 275 r fine but its not enough!!! soon as u do something u will want more after about a week so might as well spend a few extra bucks and be happy! ya it was on the 99 ya LP is workin good thing! like u said it wouldnt have started without it! hopefully this will improve milage a bit! i dont know what else to do.

 

It should help.
