I am using one of the dreaded noisy Holley electric fuel pumps. I hate the sound of the thing since I am driving it daily. I installed it at a time when I thought it was basically going to see track duty and that was ok.

I have the Blue pump in there, which is rated at 110 gallons per hour. Will an equally rated mechanical pump be comperable? I have always found the electric to supply plenty of fuel for my engine.

Can I leave the electric pump in place, or will it present a restriction?

Thanks,

Devin

The electric pump will cause a restriction, and yes a 110 gph mechanical pump will do the job equally as well.

Carter M4889 is a nice pump and still available. For a BB if thats what you have, it supplies mine.

It is what is in my Chevelle, see signature.

I also have a new one for sale on Ebay right now... mc71454

The 110 will do the job, but will have higher than wanted pressure...I guess this is fine is all you want to do is just cruise...

I would go up to the next pump a 130 and run a regulator....

The Holley billet 170 is a killer pump and does not require a reg.

I could not stand the Holley pump noise either so I switched to the Carter GP4601HP and love it. Same specs as the Blue Holley but way quieter. It will need a regulator but I assume you have one in place for the Holley pump so it should be a very simple swap.Here is a photo of the Carter pump.

Holley 12-454-20 mechanical pump.

Brian/Blue66 uses it on his 9 second 496 for six years, no regulator.

HERE is where he stated that.

Can not argue with his success....

My MJ467 motor uses a stocker OEM mechanical pump. Just thought I'd throw it out there.

I wonder if this would supply the a 500 hp engine and a small 100 shot of ritrous? I know i have ran about the same with 140gph electric pump, if its really 170 should work?
