    which electric fuel pump do I need?

    I would like to install an electric fuel pump in my 68 camaro with a 350 that puts out 325 hp. I have a edelbrock 625 cfm carb. I'm not sure what I need exactly or what to buy. what size pump do I need and do I need a regulator? Any advice would be great. thanks.

    A good $ pump is the Holley blue pump.
    Any pump that is not regulated to 6psi, will need a regulator on a carb'd street car.
    I made a brkt just like Adam's that was tubbed by DSE.

    Another great pump is the new Holley gerotor pump:

    It is queter and flows more than the old blue.

    Just noticed this text in the Holley info on the Volumax pumps:

    Two very powerful “VOLUMAX” pumps are available for gasoline or alcohol fuels. They are
    P/N 12-705-1, rated at 180 GPH and P/N 12-706-1, rated at 275 GPH. These feature a gerotor pump design which is extremely efficient and quiet. Fuel pressure is pre-set at 15 PSI and both a pressure regulator and 3/8" return line to the tank are required. The high volume output of these pumps make them the natural choice for racers who will settle for nothing but the best. NOTE: Because of the design of these pumps, it is necessary to connect both fuel pump inlets to the fuel supply for proper operation.

    thanks for the help guys. I think I'll go with the holley blue and mount it infront of the gas tank. The pictures were very helpful and even though the blue pump may be a little noisy the insideof the car is completely dynomatted so i don't think it will be a problem.
    hopefully this will get rid of my problem of no fuel in the line on startup after the car has sat a few days.
    thanks

    I have had no luck with the holley pumps they are noisy and they over heat. I switched to a billet aeromotive pump and a boost reference return style regultor. One of the best purchases I made to date. Spend the money once intead of three times like I did.


    In all fairness the holley blue really only had troubles keeping up at the dragstrip where my pressure would drop to 4 lbs.

    I would forget about the electric and go with one of these new mechanical pumps and forget about the noise, pressure problems and volume. These new pumps have you covered in all aspects and are even safer.
