Electric Fuel Pump

[flagcraig]

As mentioned I am rebuilding (rotisserie restoration) my fathers 72 Challenger.  Just found in his basement a Holley electric fuel pump in the box brand new.  He must have bought it in the 1990's.  It has the same manufacturer # from todays model 12-801 and they call it the "red pump".  It will have the Holley Street Avenger 670 on it.  Is the electric fuel pump more of a headache then the mechanical Holley performance fuel pump?  Is it a bonus to have the electric fuel pump.  Obviously I'm trying to learn as I go.

I appreciate all the help.

If you want to use an electric pump I recommend the Edelbrock 1791. I just converted a 5.7 Hemi from EFI to dual quads using this pump, very quiet.

I heard the red and blue Holley pumps were load, so I install a Mallory 4110 after some good recommendations.  It is very quiet, in fact I have to get really close to it to hear if its running.  Many places have them, here's summit:

I would use mechanical , if you have to go electric I would use the Mallory 110

X3 find a Chevy owner to sell that Holley pump to!    The noise will drive you nuts!  I'm using the Mallory 110 pump, nice and quiet!
If you go electric plan on a pressure regulator too and a return line

I installed one and love it. Quiet too.

A decent mechanical pump is simple, and will do the job easily.
Certainly has done the job for my 496.

what would be the benefit of going to an electrical?
carb only needs 6 to 7 psi fuel

[CudamanTom]

carb only needs 6 to 7 psi fuel

And that's all that an electrical fuel pump should put out. It's not the PSI or pressure. It's what you prefer as your fuel delivery system.

Or if you have to use one.  With the hemi engine with AC we can't use the mechanical pump with the Bouchillon setup.

Electric does supply a consistent flow of fuel and is one less thing to cause drag on the engine. Its free so what do you have to lose, you can always go back.  The holleys are a little noisy make sure you install an isolator on the mount.

I have the Mallory 110 and it's very nice, I also have a blue pump on my Cuda because someone thought they needed ungodly amounts of fuel pressure 14psi. Funny thing is the car also came with the red pump which is not as loud.

If you really want to complain sit in a car with a blue pump going, forget about listening to the radio or talking to a passenger.

Yes it's coming out as soon as I get a chance.

ok, sounds more like personal preference, except in certain circumstances.
the regulator and return line seem like kinda a pain,
not to mention perhaps the cost.
I have heard of folks in the past using them to deal with a vapor lock issue.
