Fuel Pump For Weber Conversion
I have a '73 that has been converted to Webers by a previous owner. The engine is the stock 2.4L bumped up to 2.7L. The current fuel pump is a Facet electric that is mounted inside the engine compartment. What I'm wondering is:
Is this the best fuel pump for this conversion? Does it have the capacity to feed those thirsty carbs at high RPM? What is the best place to locate the fuel pump? Right now it is mounted at the rear of the engine compartment. I'm worried that I could have problems because the pump is higher than the tank. Also I'm concerned about having a electric fuel pump in the engine compartment. Is there enough room to mount the proper pump by the fuel pickup on the tank? |

If it is the small, 3"x2"x2" rectangular unit, no! But, if it is the long 3"x6" round model, maybe ... I suppose 1 rectangular unit per carb. could handle the flow, but a larger pump seems in order, to me! And, a pressure regulator adjusted to 3.5 psi.

I am currently using the square facet fuel pump on my 1971s 911. I havent had any problems with starvation of any kind but it is a little noisy. The important thing is pressure not volume. Dont go above 4.0 psi like Early-s-man stated or carbs will start having problems. The borg/warner cylindrical unit is what I will eventually convert to because it will sit fairly well on the saddle of the original pump.

As Louis suggests, the original fuel pump location -- on the left side of the transaxle where the fuel line comes out of the pan seems logical. A stone shield to protect pump, wiring, and hoses from damage might not be a bad idea, either--expanded aluminum seems appropriate, similar to the stone shield on the oil tank!
