Mallory Fuel Pump Regulator

Shadylane · 05-05-2016, 09:42 AM

I bought a used Mallory 140 electric fuel pump from a friend for my 302 2bbl Ford stocker build. I know this pump is overkill for my application but my question is, do I need to buy a Mallory regulator or can I use a Holley regulator which I have several of. Just don't want to spend any more money than I have to.

Thanks, Kelly

No. It's probably something like this that I found on Summit just now. Click on the Instructions link and look at the installation diagrams. A regulator goes in the line anywhere between the pump and the carb. It just has to fit the line size you use. I have a Magnaflow regulator on a Holley Black pump feeding the 4bbl on my 302.

EDIT: Wire it to a relay to keep the high amp switching stuff out of the cabin. If you don't know how to do a relay wiring, here is a good instruction sheet at this link:

Any 30 or 40 amp 5 pin relay will do. You don't need the one in the link. May $6 not counting the wire and connectors.

Dale, have you had any volume issues with your Holley black pump.

Make sure you have a good filter between the tank and that pump. They are a gearotor design with very tight clearances. Anything in the fuel will bind it up. Great pump if you keep it very clean. The Holley regulator should work fine.

Thanks George, that is what I wanted to know. I already have a canister filter so I'll make sure it's in there before start up.

Not yet, but it's only a week old.

My Magnaflow 275 sprung a leak on Thursday and I hit Summit overnight for a new pump and it had to be one in stock. I wasn't pleased with a $400 pump springing a leak so I gave the Holley a shot. It's feeding a 600 cfm Holley 4150 on a cammed 302 with 10:1 compression. Jetting was lean and will be 67 primary and 76 secondary for this weekend. I have a data recorder on my A/F gauge, but I keep forgetting to punch the Record button when I get to the water box. Still a bit green...Fuel pressure is 7psi.

I know the filter question wasn't directed at me, but I have a filter before the pump and another before the regulator.

EDIT: The Holley Black is one loud fuel pump.

I have been using a Holley black for a few years now.
I don't think I have any issues.I don't have a fuel guage that I can see from the drivers seat(working on that).
I, as well, use a filter before my pump.No filter after.I also run 7 PSI.
And yes this pump is load.Not hard to tell if it is on or not.
