Well I installed a spin on fuel filter because the filter base kept leaking after I had it off twice, I think a small freeze plug was leaking. I was fighting a surge when first started and now it is fixed. I wanted to find a filter with a drain on the bottom but the napa brand filters were all too long. I have heard a lot about the racor filters. How good are they and does napa or carquest stock them? Any suggestions or comments on this change?
