Re: Help with hooking up an electric pump.

You should bear in mind if you have an electric fuel pump running thru a stock fuel pump, you may be pushing enough pressure into the carb to cause a chronic flooding condition.

If the stock pump puts out 4 pounds and the electric puts out 6 pounds you will be feeding 10 pounds pressure to the carb.

A needle valve that is only meant for 4 pounds will not hold 10 pounds. In fact it would be lot happier at 2 pounds.

Best solution: forget the electric pump and fix your car so it runs properly.

Next best: Add an electric fuel pump, wired so it is only on when the key is on. Put a switch on the dash so you can switch it on only when starting from cold or in emergencies. Also, add a fuel pressure regulator set to 2 pounds to the carb.

Worst solution: Pile on the fuel pumps and let her rip.
