Thread: Need help selecting a new fuel pump

Tweet

My holley pump that my dad had put on my monza before i was even born finally bit the dust, I need some recommedations as far as brands and max psi i would need a pump to run.

*Has to be electric
*Cannot have a regulator (dad said i dont want one , can someone explain what it does exactly?)

Im looking to get the max bang for my buck here as im kinda short for cash at the moment but need the pump in order for the car to stay running more than 100 yards lol,

Thanks in advanced,

Slade

You havent said what motor you have in this car.Regulators do exactly that, regulate fuel pressure. Electric pumps put out way more pressure than what a caburetor needs, so the regulator will tone down the pressure. Most regulators are adjustable ,which also means you will need a fuel pressure gauge to see what pressure you need. There may be an electric pump that does not need a regulator but I dont know of one. Most all electric pumps should have a regulator because you need to run 4-7 lbs of pressure for a carb, no higher. To be exact, running 4-5 is all you need for street driving.
There are tons of companies that make electric pumps and I would only go with the name brands, Holley, Magnafuel, Carter...........best thing is to check out Jegs or Summits websites.
I don't know why you just dont use a regular diaphram pump that attaches to the motor. You dont need a regulator for one of them.

You might want to try one of these, mount back by the tank, no regulator required. They have gone up in price a bit (used to be about $35), but they are a good dependable unit.

Another thing is to make sure you use a relay when wiring up any electric fuel pump.

I guess I would save my pennies and just get another Holley pump, though there is a $39 Chinese (I assume) clone advertised here:KMJ Performance*::*Fuel Pumps*::*ELECTRIC FUEL PUMPS

This company has mixed reviews of their products, but in today's performance parts world, not unusual.

And a regulator - some of these electric pumps output really need to be cut back to the required 4-6 psig that Holleys and Edelbrocks can use

Use a Mallory. Guys on the Team Chevelle forum recommended them, and after my Holley puked out on me, I got a Mallory 4070M that puts out a maximum of 6 psi. With that kind of pressure you could get away without a regulator. It is not nearly loud as the Holley pump and it does not get as hot.

yea my old pump put out 7 psi and it didnt require a regulator, Its a chevy small block 350 btw, Oversized cam idk if that matters, so 7 psi is too much ? could my cutting out problem be from too much fuel then ? link to the post i asked about it is here Cutting out Problem .. PLEASE HELP

Why not just a quality manual pump??? They work fine and usually outlast a couple of electrics!!!! What's the deal with not wanting a mechanical pump???? They work great on a mild street engine.

No room for one unfortunately id rather have a manual one but that 350 is an extremely tight squeeze.

Thought the Monza's had a v-8 option??? Maybe not all years or something? What's in the way, anything that can be tweaked a bit? Also, there's a bottom cover option on some pumps that have the lines going straight down rather then to the side.....

Dave the Monzas did have the V8 option but the Vegas and Monzas ran an in tnak pump (yes even on the 4 Cyls). As I recall from back when I had mine it was either frame interference or interference with the Hurst elephant ear motor mounts.

Didn't know that Mike... Guess I've never looked close under the hood of one, too bad a bit of trimming or grinding wouldn't make room for a mechanical pump--they're still the most trouble free pump on the street....

" --they're still the most trouble free pump on the street...."

Totally agree with you Dave,,,,and as I recall I sure would have put one on if I could have gotten it to fit.

The Facet won't keep up with a mild small block at WOT, Carter is a good quiet pump or Red top holley, red top doesn't need a reg.

“......The Facet won't keep up with a mild small block at WOT......”

That I would have t with o disagree with you on that....it keeps up with this running thru the all 4 gears and sustained WOT.



And I ran one on the Tri-Power 383 stroker in my 58 Chevy for over 10 years also with no fuel starvation issues.
