Electric Pump with Performer Carb

I just got my '97 Silverado motor in the Chevelle and I'm ready to bolt on carb and accessories and go!!! Finally. Thanks for all the help up to this point.

Now, I'm going to have to run an electric pump since my block does not have a mechanical provision. I was thinking of using Carter's #P4070, which is a "street" pump rated at 72 gph with 5 psi, using 1/4" npt fittings. I would think this would work well with the 600 cfm edelbrock performer I'm using on this mild 350. A few questions, then:

1) Will this pump work well?
2) Do I need to use a regulator?
3) Can I just wire it in to a "keyed" slot on my fuse block?
4) Where is the best place to mount it and a good way to plumb the lines to the carb?

Thanks everyone! Almost there. . . .

im running a similar set-up with a small block chebby, however im using a holley street electric pump with a edelbrock 750 carb. so your pump and fittings are very similar to mine and i've had no issues!

i do NOT think you will absolutely need a regulator. Just the electric pump should be fine by itself, but maybe one of the great minds can correct me on that??

its a breeze to wire it up.It should only have 2 wires coming from the pump. one is for ground and the other is your power supply. you COULD wire it up to an IGNITION-on wire that way when your turn your key your pump goes on. I didn't do it that way. I chose to go with a toggle switch for it. Just a nice feature to be able to cut off your pump in case of an emergency at the 1/4 mile track.

As far as the lines, i just used good rubber fuel hose from the steel fuel line up to the carb. Again i assume you have steel fuel line that runs from your tank up to the front of the motor area?

Mounting is important. Remember, a fuel pump will PUSH better then it will PULL. Thats why most pumps are mounted in the tank or near the rear of the vehicle.

good luck

Mont the pump as close to the tank & low as possible. Also use a relay when wiring it up.
