I have run up to 3 filters on a stock pump for the same reasons

just did not replace anything

rusty tank and fuel line

2 filters before the pump and one after the pump worked fine,till I got more rust holes in the line

then it would blow air bubbles in the filter after the pump and had supply trouble

I added a little cheap in line banger pump to help keep fuel to the stock pump and it worked fine for a while

I changed the line and removed the extra pump,left the 3 filters

ran fine with it like that for a long time
