I have a Holley Electric pump and it has done flawlessly. I had a Carter on the same car and the pump itself got insanely hot. it actually boiled the fuel in the pump. I do not have a return line. The holley is much quieter and pulsates less than the Carter. In hot weather I had to stay above 2000 rpm to keep from vapor locking with the Carter. No problems with the Holley. The Carter would also not keep a consistent pressure because the teperature issues.
My dad has a Mallory and it works much the same as the holley, maybe a little bit better than my Holley.
Bottom line, to get a good pump it's going to cost a hundred bucks or more.
