I had dead headed my last pump and I always thought that it added load (amps) and shortened the pump life with added heat. This time I got a 3 port Mallory regulator and added a short return back to the suction side. I can regulate psi down to almost nothing and the electric load is less than half of what it was. Plus it is a bit quieter too. Overkill ?? Perhaps. Effective?? I think so. Besides what else do I have to keep me busy besides body work and more sanding!!

Jerry,

Thanks from me too as I have my filter after the pump. See attachment. Will have to rearrangement for filter and pump. Must be a good thing my build is going so slow.

Jack.

That is what I experienced back in the early eighties, using a holley pump, it got hot and quit, but it took a while to fiqure it out, that is why this time I decided to run a return line.

Yes but, I just return into the inlet side, not the tank!

Are you running the line back behind the pump...?

Yes. The relief port from the 3 port regulator, I reconnected back into the inlet of the pump. I've got 4 PSI going to the carb.

Thanks, that just made my life easier...

And that's why I did that! 'ccause we're known as the helpful website!......... Nah, I couldn't see any reason why it would make any difference. Dump it into the tank or into the supply line. I love how it primes the pump after sitting a few weeks too!
