Adding an elec fuel priming pump

[dave5237]

If mine has been sitting, I spray a little starting fluid, or take off the air cleaner lid and pour a few drops of small engine fuel into the carburetor, and it fires right up.

I did that for years. You are right.,but wait till you drive it in hot weather and park it for a while and the gas boils off. You will look silly like I did when you always got to squirt it when trying to restart it or you have to crank and crank to get gas up to the bowls. I finally took the electric fuel pump route with no problems now.

Since my OP, I am now considering mounting the priming pump on the frame rail in engine compartment, instead of by the fuel tank.

With this in mind, would it not make most sense to plumb the priming pump in parallel with the mechanical pump?

i.e. -

If you do that, wouldn't you need two one way valves as well..

Hey 62 Dart - I would suggest you find out how much restriction that Holley has when it's not energized. If none (or very little), would plumb the simple way. If not, then... I have a similar problem, but drive the car every few days so it doesn't come up.

Frank; Here are the instructions for mounting Holley's low pressure (red) pump:

PUMP MOUNTING AND INSTALLATION:
The best location for mounting any electric fuel pump is the rear of the vehicle. The inlet and outlet of the pump must be mounted below the lowest point of the tank. This is necessary to allow for an adequate fuel supply. The pump is designed to push fuel and not designed to suck fuel out of the tank. It needs to be gravity-fed or if it’s pulling from the top of the tank, it needs to develop a siphon feed to the pump. The pump should be mounted on the chassis, in a vertical position with the pump

Hi Ron

I really don't want the noisy electric pump running all the time in my cruise car....

If you can hear your fuel pump in the car then you don't have enough motor. :eusa_whistle:

I don't think so, as each pump has non-return valves inside them.

I've read that before, thanks Dave. More important if the electric was your one and only pump. I'm only using it to prime dry carbs.

I'll PM you my address to send me a nice Hemi!
