    I have a 79 camaro I just put the motor in but it’s a mid 90s 350 without a mech fuel pump boss. What electric fuel pump would you recommend and do I need to run a return line and if so how do I do that? Been out of a camaro for 7 years. The motor is only a 260 horse motor but just want to get it going so I can do the bodywork then put a new motor and trans in it.

    Assuming this is going to be a low psi carburetor setup? Both Carter and Holley make a slew of pumps that will work without a return line or regulator. I had good luck with my last Carter pump. Just remember when selecting a mounting point that electric pumps push gas and are not very efficient at drawing gas like the mechanical ones. Holley has some fairly new inline electric pumps that might work, I don't have any experience with them.

    I have a 4070 from napa. (same pump) Mounted under the outside trunk area on the passenger side. i used some tire sidewall pcs to isolate it, Works great with my 383 stroker. Need to run a power circuit thru the oil pressure switch for safety. (in case of crash) I have a momentary priming switch for initial startup. Fairly quiet and provides plenty of fuel at 50 GPH.

    I run a Mallory Comp 140 on my street car (electric) I figured the one on the race car has gone almost 30 years so that good enough for me.

    That year should already have a return line.

    Just don't buy one of those $15 dollar inline pumps. Get you about ten miles from home when they quit.

    I would go with Carter over Holley as well. The AZ heat eats pumps and the Carter seemed to outlast Holley red and blue pumps. A return line with a regulator does make them last longer than a dead-head setup.
