New Priming Fuel Pump

I am taking care of the last few items on the SuperComp car to get it ready to race. The car has a mechanical belt driven fuel pump on it that requires the engine to be running in order to pump gas to the carburetor. This makes it very difficult to start the car if the carburetor bowls evaporate all of the fuel out of them or you run the car completely out of fuel. You have to roll the car on the starter until the pump picks up fuel (Very hard on the starter) or squirt gasoline into the carburetor to get the engine started. This is a dangerous way to start an engine because it could backfire and burn your arm.

I re-plumbed the fuel system and added an electric pump to prime the carburetor so that the engine will start until the belt driven fuel pump starts pulling fuel from the gas tank. It is all plumbed now and only needs the electrical wires hooked up.

I also added a nice inline fuel filter (there was no fuel filter on the car) to make sure small jets in the carburetor don't get debris in them.

This is a much better arrangement!
