I am looking for any info or suggestions on a good performance mechanical fuel pump for clevelands. The only one I have found is a Holley - Up to 80 gallons per hour (free flow) 7-1/2 PSI shutoff pressure. Will this be enough to feed nearly 400hp?
How hard would it be to rig up an electric fuel pump?

Thanks,
Cody

installing the electric fuel pump is easy. i am using a ac delco(i know, i know) thats self regulated to 6.5 psi fuel pressure and is good for at least 400 hp. i highly recommend using a relay. painless wiring has free instructions to download for wiring electric fans, fuel and h2O pumps with a relay. here's the link:

on a side note, i opted to make my own fuel pump block off plate. I left the stud in the block from the factory and used the regular bottom bolt with a spacer and a nut just incase i get stranded by my electric pump and have to use the mechanical pump to get home.

Fuel pumps for 400 hp are no big thing. The holley mechanical will be just fine although 7 1/2 lbs pressure maybe a little on the high side. Then again depending on the carb it maybe fine also.

I have had good luck with the eledbrock pumps, although I didnt look to see if they list the Cleavland application.

Electric pumps are ok but I question the relialbility factor with them. mm

The Holley pump is now out of the question, they quit making them for Clevelands, and Edelbrock doesn't make one either. The only other mechanical pumps(that I can find) are made by Mr. Gasket and Mallory. The Mister Gasket pump has way more pressure than I need - 8psi. The Mallory Pump has 6-8psi, and flow 70 g.p.m.

I have an Edelbrock Carb, and I think that it's supposed to run at around 6 1/2 psi. Could I just use a pressure regulator?

If I was to use an electric pump, would I need to run a fuel return line?

Mallory pump

I've run the Mallory for years. Dead nuts copy of the Holley. I always run a regulator. The Edelbrock seems less sensitive to the pressure than the Holley did.

Yes you may use a regulator if needed. I reccomend the Holley.

No a electric pump shouldnt need a return line and you may use a regulator on it if needed also. Some have adjustable regulators built in.

Just for the record I just put a new eldebrock carb on my truck (Hurrah! No more fuel inj!!) and its running fine with 6 1/2 lbs at the carb. mm
