My mechanical pump is crapping out, and I'm ready to go electric. What's the most reliable pump out there ? I'll need 6-8 psi and about 70 gpm.

70 G.P.M.???????? How big is your tank? :-)

I have been running Holley red which is 7# with out a regulater.It is about three years old now and has worked fine with no problems so far.How ever I do carry a spare just in case....Ray

I am running a blue Holley electric pump on my coupe. I have it installed near the tank, insulated it with rubber, wrapped it in pipe insulation and it still is noisy. At highway speeds you don't notice the noise but when idling it can drive you nuts.
I think it is running at 25 psi. Not sure though.

Is there another brandout there that makes less noise?

i, at one time ran an electric pump only and worked fine till one day, it died and there i sat in the middle of nowhere. caught a ride to the nearest town and was able to find another electric pump. i felt pretty lucky to have found one, it was a small town, the local parts house just happened to have one on hand. i installed that and when i got home i put a mechanical one back on it too.

Is there really that much problem with after market electric pumps, I have a mechanical one. but other [ older] rodders told me they never found one they could trust. All the new fuelinjected cars have them without much problem what gives
Dave.

a lot of the elect. pumps now are in the tanks, they are more trouble free, but not infallible. i live in a small town and the local shop here replaces 2 or 3 in-tank ones a year, not a good average. they have to order them in and don't carry any other electric pumps. the local parts house carries a fair supply of manual pumps. my personal opinion is that mechanical pumps are more reliable,if they start to act up you can still limp in, an electric usually just quits. check out re:fuel pumps, the consensus there is the same.

Thanks for the input. The reason that I get the yips about electric pumps is that I'm in the machine testing business and it's always the electronics that drags a checkout down.
By the way, I thought my mech. pump was bad because it seemed to be seeping oil (couldn't figure out how, but the only oil was always on the top of the pump and the frame near it). While cleaning it up from under the car, I happened to glance over and see that the pan rail was missing a bolt. Right next to the pump. And not a bit of oil any where on the pan! Put in a new bolt and everythings ticketyboo.

glad you found your oil leak, nothing worse to make a mess. sometimes are a real pain to find too.

I had a stock mechanical pump break on me on my way home from Louisville. It broke the spring in half! But, it was the only thing I didn't carry a spare of. I bought a new mechanical pump, and don't even worry about it now, because it was so rare. Everyone I showed the broken one to said they never saw anything like it. My feeling is that unless you are racing and need the consistant fuel pressure, stick with the mechanical pump.

I haven't run an electric pump in years because I hated the buzz of the old Carter diaphragm. I just bought a Holley to go with a mech. pump on a built 455 with 2-600's. But from this talk it's evidently no quieter. I recall a setup I liked. You can run tee off the line before and after the electric pump and run a loop around it with a check valve in it. Then set the electric pump to only activate when needed with either a low vacuum switch or a microswitch on the throttle.

Mechanical pumps can also cause problems when the diaphram leaks and dumps raw gas into the crankcase.
Ive mixed emotions on the subject and have run both. On the modern family drivers Ive never had an in the tank pump failure and my daily drivers are typically in the 150K mile range.
The one place I always go electric is on multi carb flatheads, dont know if there are any other flatty drivers on this group.
