2 fuels filters on my truck?

85 s-10 1.9 2bbl carb. i have 1 filter after the tank and before the mechanical pump. i also have 1 after the pump abd before the carb. the truck runs fine regaurdless. im wondering as to why there would be 2 fuel filters on the engine.

Anal previous owner?

If it runs fine right now, don't worry about it. In the future, one is all that's needed. Any more is just a restriction to fuel flow.

i dont think it was an anal previous owner. i biught it from a mexican from the u of a. i think thats also y it is a bit sluggish in acceleration.

every car has a general screen to keep out large material before going into the pump...after the pump they will put it through a finer filter before it gets injected into the engine..

some vehicles use a primary and secondary filter to ensure that there is no debris and dirt going into the system...diesel trucks do that guaranteed cuz of the pressures and whatnot that is delt with..
