Mechanical fuel pump to electric fuel pump as easy as possible.

Okay, first you need to understand that electric fuel pumps can produce a lot of pressure. A carburetor can not handle what most will supply. You need to find an electric pump that will produce around 7psi. Once you get it, locate a place on the inside of the frame rail to place it (where the present fuel line goes). You will need to cut the steel fuel line so as to fit the pump within the lines. Once that is done, you will attach the pump on both sides most likely using rubber high pressure fuel line and clamps. Those directions should come with the new pump. Once that is done, you need to provide power to the pump. The power should be switched, meaning only on when the key is in the run position. Again, once you get the power, follow the directions that come with the pump. NOW KEEP THIS IN MIND. Your vehicle doesn't have an automatic shut down in the event of an accident or roll over. This can be dangerous. The pump will not turn off automatically. If there is a fuel leak, it will continue pumping fuel. If there is a fire, it will constantly be fed fuel until power is lost.

I have to ask, why an electric pump when a mechanical is under 20 dollars?

Let me know if you have other questions.
