While I'm upgrading things, I have to do something about my Holly electric pump. It's obnoxiously loud and I'm contemplating going w/ a mechanical. It's hooked to a 500 ci wedge in a '68 Charger that will mainly see street duty with maybe a trip to the track a year. For my purposes, would the Carter Super Strip pump be sufficient? (With that, a question: the description states in has 1/4" inlets - does that seem awfully small for a performance pump? I have 3/8" fuel line btw...)
If not this pump, is there one to recommend that would do the job?
Thanks!

Any high perf mech pump should work good.

If the buzz is to loud then try the Carter, Eddie
or any one of the mech pumps. They can pump
enough fuel for a 600 H P or better motor.

Snap your neck, mega G-force launch, is all I want!

Yes, that pump is too small for your application. Suggest a Holley HP125 or HP150. These are gerotor pumps - quiet and will deliver the fuel you will need for that 500 incher.

I replaced my loud Holley blue pump earlier this year with one of their new gerotor pumps. I measured its output to my carb and it was basically the same as the old pump. But it is a lot quieter and more of a whirrrr rather than a growl.

Master, again and still

Back when Bob Glidden ran a plymouth Arrow in pro stock (and was the champ) he used two stock Holley blue pumps. With the proper fuel line and pick up these pumps will support a LOT of horsepower for a very reasonable price. Who cares if they make noise. At least you can tell they're running

IIRC, that Carter fuel pump has 1/4 female NPT fittings on it, not tube fittings. You need to put your own tube fittings on it. Local auto parts store should stock something you can use for your 3/8" line

I have a new Mallory pump sitting in the box waiting to replace my holley blue pump when it dies. It's got 8 years of street driving and it's still going strong. They are noisey, but reliable.

That was many years ago.

His car is a street car, the noise sucks.
Almost any mech pump will do the job for most street cars.

What? Turn off the friggen fuel pump, I can't hear you!

Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.

It does seem to work OK, but I can hear it clearly over my exhaust, and I'm running headers and some fairly loud flowmasters!!! The only bonus I can see running the electric (if a mech can indeed flow enough fuel to keep my motor happy) is the ability to prime the carb after it's sat for a while.
So is the consensus that the Carter (with it's 1/4 inch bottleneck female inlets) could handle this motor or should I go w/ one of the other's recommended??
Thanks for the replies!!

The nice thing about the Holley is that when you turn it on you know when the bowls are full 'cause the tone changes.

Electric pumps are also better to fight vapor lock in hot area's. My buddies 68 Cuda 383 used to vapor lock on very hot days but never a problem when we installed an electric pump. The fuel is under pressure with the electric pump vs fuel under vacum being pulled up to the mech pump. I will take an electric pump any day over the mech pump. My sons holley red pump is 12 years old and still going strong and mine is 3 years old. Ron

I understand that, my question is I've got a 3/8" pickup and line all the way to the carb and w/ the Carter, unless I'm missing something, it chokes down to 1/4" in and out of it. Seems like a mismatch, but I do see a lot of performance cars using them... The Holly mech uses 3/8 inlets and outlets I believe, but I don't know anyone who uses it. Hmmmmm.

I went through two of those pumps ( the first one leaked ). Yes, they are 1/4" NPT in and out. Mounted mine by the gas tank and ran a 3/8" line to a single 750 Demon. At the time my small block was making about 425HP. The pump would not keep the carb full through a full 1/4 mile pass. It would run out of fuel just before the lights. Went to a Holley HP150 geroter pump and I now go through the lights with 3-4 psi ( making considerable more HP ) . Just my experience, but I will never buy another vane pump. They're for kids!

Just get a Mallory electric, swap it in place with the holley and be done with it. Keep the benefits of an elec pump but not hear it growling.

I had one on my Duster. 444ci 11.43 @ 120mph with the 110 street/strip version. You'd hear it just a little when you put the key on but thats it.

Mallory is a little pricey but worth it for the quiet street runnings!

You Run Flowmasters and you worry about a loud fuel pump???? Who cares at least you know its working as previosly stated and parts to repair are readily available. I get 7-10 years out of them and replace them keeping the old ones for spares etc.
