I could not make a Carter High Volume mechanical fuel pump work for the life of me. As soon as it heated up any it would start dropping in flow.

I don't give up easy but ended up dumping the mechanical fuel pump and went electric.

Talked to a lot of people about it including the manufacturer reps and most agreed its a common problem on high volume pumps.

Is this a high volume?
