The original "Fuel Filter screen on the end of the pump ;
that is shaped like a tiny sock ;
It can be replaced with a later model in tank fuel pump sock for a 1986 - 1992 V6 chevy truck;
with throtle body injection TBI ,,,that looks like a small pillow !and works just fine !
>It will press on snug !
Just add a larger easy to relace after- market filter in the engine bay away from heat !
and if the carburetor has a interior filter ,,,,use it as well !
I hope this helps !
