Think i'll try a mallory 110.
Almost went with a aeromotive but buy the time i'm done with the pump,regulator and a new filter, it's over $500 bucks.

I have a mallory 140 with brand new reg for sale if interested. Pump has 1 season on it, I didn't use the reg it came with, it's new.

Aeromotive? the guys runnig a stock 502 .....a little over kill I think.....I've had good luck with the Mallory 140 on a roller 502 making 525hp at 5200rpm.

I was thinking the mallory 110. but it seems most of you use the 140.

Dave F, what'ch you want for the 140 and reg you have?
which regulator is it? #4307 (2 port) or #4309 (3 port)

Dave F

I have both, the 4 port/return and the one that comes with the pump. I used the 4 port, that's why the other is new. I still have that as well. You would only need the one it comes with if you're only feeding a natural asp carb. The pump has an internal bypass that you would have to reset. I closed off the internal bypass so the other reg could return back to my tank. I used it for a small Pro Charger. (It's just a "set screw" and nut on the base of the pump)

I haven't given it any thought about a price. Let me take a look at it. It's still in the box. Let me make sure everything is still there (it comes with barbed hose connections that I never used either) and I'll contact you by this weekend and we can talk about it.

Go with the Mallory Comp 140 marine, it comes with the regulator.
You will need a oil pressure switch & fuel pressure gage.
I have had great luck with this setup!

I was told by Paul Pfaff racing engines red seems to burn out before blue although blue is 15 psi you will need a pressure regulator to bring it down to 7.5psi.

price: $110 w/ regulator

I've got a new in the box Mercury Quicksilver electric fuel pump #805656-2 if interested. I bought it for my 454 mag late last fall.
Retail was $149.00 I'd take $70.00 if interested.

Can someone explain how the oil pressure switch works with the electric fuel pump? Is there enough oil pressure created when cranking the engine over when starting, to energize the fuel pump? If you lose oil pressure, does the pump shut down? Wouldn't this create a lean condition?

Hello, RLW,
The oil pressure switch is a switch that will disable the pump if the oil perssure drops blow the switch cut off point. You also need a relay. The engine will eventually make enough oil pressure to run the oil pump when starting. We usually run a circuit to the starter. If you loose oil pressure, you don't care if you get fuel or not, in fact, the idea is if you loose oil pressure and have a leak or fire, the pump will stop pumping more fuel on the fire. If you need more, pm. The options are too numerous and I don't know how to post the wiring diagram, but I will happily fax one to you!
One more thing, if you have a VI block, you could run a mechanical pump and save a ton of work and money and be safe and sure of fuel supply!!!
