Do you have to use Holleys projections fuel pump or can I

[73K5Kid]

use an aftermarket one. I did a search and didn't come up with much. Cause I am thinking about buying a used pro-jection and it needs a fuel pump. I don't want to have to spend another 180 bucks on there fuel pump. If I can get one cheaper. I know it has to be an external pump with 15ps.
Thanks

Holley's electric EFI fuel pumps are legendary for their inability to function for more than a few weeks or months. I'd recommend buying anything BUT a Holley pump. A stock pump from any TBI application will provide the correct pressure.

I personally would go with a Aeromotive pump and trhow a regulator on it... /forums/images/graemlins/thumb.gif IMHO, I am with Harry...Holly pumps eat the dust a little too early and when they do work the MOFO's are LOUD....

Don't the pro-jections themselves have a horrible reputation?

Not sure of specifics, but I recall hearing things about the pro-jection setups.

Might want to check around to see how people like theirs that have been running it more than a few months.

I've been using one for eight years with no problems on the original pump, but I have heard stories of pumps not lasting also. I suspect it has to do with sucking trash through it, follow the directions and use a good filter before the pump. If the system needs a new pump, it doesn't matter what pump you use as long as it is capable of the output pressure. IIRC the voltage output to the pump varies with load and the book recommends using a relay so high output engines always receive 12v, if you use a pump other than theirs, you would probably want to do this.

I've had my Holley pump for over two years now. And you cant hear it run at all.

Consider yourself lucky! /forums/images/graemlins/wink.gif I know people that have gone through 2 or 3 Holley pumps before switching to a different brand. After that, their Projection systems ran pretty good. /forums/images/graemlins/thumb.gif

I am with Sandman on this, I had my projection using the holley pump for two years with out a problem. Drove it almost every day too. I think pump location might be some people's problems.

Could be, but when I hear the same story from 8 or 10 different people, then I have to wonder about the quality of the pumps. Perhaps Holley wised up and improved their design in the last few years, but they already tainted their reputation with me. /forums/images/graemlins/frown.gif

The Holley Pro-Jection has a regulator built into the
Throttle Body Unit. My first pump lasted about 2 years
or about 6000 miles, got Holley to replace it, never
returned it, but when I opened it up to see why it failed
the electric motor failed the Commutator and rotor windings
looked like they where sand blasted. And I used a good
filter before the pump(10-20micon's). Also stamped into
the outer case was CARTER and numbers.

Second pump is making some noise now, so I will cross my
fingers and hope to get some more use out of it. But I
too am looking for an Aftermarket pump, so far
I hear the Bosch($$$$$) is the way to go.
