electric fuel pump vs. manual fuel pump

I have a 1971 302 that I am putting im my 1963 comet S-22 conv. What are the pros and cons of each and is there any HP gain/lose for either. I have a performance cam and an XCELorator 7515 manifold but no Carb at this point (any suggestions?) on the engine.

Thanks,

If you werent going make a lot of horsepower, I wouldn't go electrical. Mechanical pumps don't really rob much if any HP and they are a lot eaisier to install. The only reason I am running an electrical is i'm going to be making over 500 hp and needed the constant fuel flow and gph the electrical and give.

There is nothing wrong with running both. I run both on my 347. A Holley mechanical and a Holley blue at the tank. On the street I run on the mechanical only. I have to run the Electric at the track or I run out of gas at the 1000'.

Thanks for the input. I guess I will stick with the manual pump.

For a daily driver i would go with a Mechanical pump

The bad thing about manual pumps is you have to keep pumping them... with one hand on the wheel and the other on the pump lever you get tired out pretty quickly. And if you have a manual transmission, forget about the manual pump, unless you've got three arms. Oh wait, were we talking about MECHANICAL pumps?

Mechanical pumps are far more reliable for a driver. If you don't NEED an electrical pump, stick with the far more reliable and affordable mechanical pump.

Very few street/strip cars really NEED an electric pump.

Good Luck!

Man, I really feel pretty stupid. You are right I wanted to say mechanical not manual. Thanks all for the info I will go with a mechanical.

I've had good reliability out of stocker mechanical pumps. I've also had zero problems running Mallory electrics. I've had major problems with Edelbrock mechanical performance pumps. A mechnical pump is fine for a street car but so is a Mallory 70 electric. I like the electrics because I can switch them off. Hide the switch and it's a theft deterrent. Switch the pump off, run the car out of fuel and there's less likely to be a fuel spill and a lot less fuel to dump when you pull the carb.

Carter makes a great mechanical pump. Get the standard pressure unit so you don't need to use a regulator... it's around 6psi, which is perfect. They are not that expensive, and outflow stock pumps. Dead reliable. These are the ones that look sort of like a stock unit... not the huge things Edelbrock sells.

Good Luck!
