electric fuel pump

65notch · Aug 24, 2005

those of you who have electric fuel pumps: ive got a mechanical edelbrock one right now and id liek to go to electric. i have a mild 289, stree driven. any suggestions?

A holley red doesnt require a regulator and will put out about 7 psi,a holley blue will need a regulaotr and puts out 14 psi.

I just got a rebuilt Holley red for about $60 on ebay. I hear they flow around 65-70GPH/250LPH @ 7psi, so it ought to be more than enough for my 320hp 302.

I'd go with a Holley red, they are also a lot quieter than the blue. I have a blue and am on my second one. Electric pumps are supposed to be gravity fed, which can be difficult to get it low enough sometimes. I'm going mechanical next time I have a choice. I run mine off of a relay from a strong power source so it gets constant voltage.

Holley Red here too.
and if you want to get rid of allot of that buzz, you can mount it using vibration mounts. They're basically a piece of rubber about 3/4" thick with studs coming out of each side. like the ones MSD sells but on a bigger scale.

I would not do it unless you are starving now. It is a pain, they are loud in general, and won't do anything for performance.

i started hearing a clicking noise comming from my mechanical the other day. it only did it for a little while. so i thought maybe it was starting to go out.

how do you tell when an engine is starvin for fuel.

it will probably surge in the upper rpm's

Nascar engines make around 800hp all day long with mechanical pumps. There is nothing wrong with them. If my A1000 goes out, I'll look real hard at one of these http://racepumps.com/ . They should have the SBF model out soon. Mild street driven 289 should be OK with a stock fuel system.

Was kinda pissed when I saw that pump.

Where have you all mounted your Holley pumps?

rbohm · Aug 26, 2005

i have used a carter electric pump on my grand marquis. it works just fine with no noise, and no regulator. best place to mount an electric pump is as close to the tank as possible. on the merc i put it in front of the rear tire.

67bluegt · Aug 26, 2005

Best place to mount a Holley pump is as close to the tank outlet you can get and stay low without getting in the way of anything.

short answer = stay mechanical
long answer = stay away from the electric pumps unless you are planning on making massive horsepower. with a supercharger or turbo. i had two holley blue pumps, one cracked and leaks the other is just crap. i am using a mallory 110FI and it is working good so far. had i remembered to install an eccentric i would have used a mechanical pump since they are good to about 550hp with boost. should you feel compelled to change to electric choose carefully for you don't want to be rebuying parts a couple months down the road. figure out if you have plans to add boost because that will directly affect what pump and line sizes you need, it also works better with a return line setup vs a dead head regulator like the cheapo holleys. the mallory pumps are pretty quiet and appear to be built better than the holley pumps only time will tell so i can't say for sure. there regulators are also constructed better.

I wouldn't change to an electric pump either. I've had firsthand experience with the Holley Blue Pump and was not impressed. It was way too loud, especially at stop lights and burned up twice in less than a year. Reliability becomes a big issue with electric parts unless you're using factory components that are engineered to last 100,000+ miles. Many times the aftermarket companies don't engineer their products to last that long. Their warranties are usually 90 days or so.

On my latest buildup, I used a Carter mechanical fuel pump to feed my 306 that's equipped with two four barrel carburetors. It produces 7 psi of pressure and feeds both of them just fine even while at the Dyno where I made 307 peak rear wheel horsepower at 6,400 rpms (A/F was @ 12:5.) At the track it'll run strong thoughout every gear all the way through the traps.

I don't think you'll be disappointed if you stay with the mechanical unit.

My blue Holley pumps work fine and I drive the **** out of my car. I also track it frequently and drag race. It has a 427 stroked Windsor and 250hp NOS. Never any problems for almost two years now. Reliability mostly depends on if its done right or not.

My blue lasted about 8 years.I wired it with a 10GA and switch.The only problem was it leaked at about 7 years wich cost 25 bucks for a seal kit.It was mounted over the axle,I now have a Summit Billet pump(18 psi) and Paxton 4 port regulator

Check out this link to Century Performance. I know others have pissed on this link in the past, but this brings some tech versus their WAG.

As far as electric pumps being too loud, use a gerotor style pump and you'll barely be able to hear it over your engine. The other thing to consider, you should install some kind of inertia switch in case you ever get into an accident and become incapacitated and can't shut the ignition off yourself.
