Yeah, my fuel injection guy also said it may be better with bigger lines, but initially he didn't have the set up and so we just replaced the filters and the pump too (the car had sat too long). Worked great as I really don't pound on the car too hard, but now about a year later I am getting some restriction under heavier load and I only assume it is the filter again. Looks like the car has Earls filter, so I probably need this below according to George's info. How do you guys know this stuff? How does 11/16" translate to 6 AN, I don't have my decoder ring.
