New Aftermarket Fuel Pump Issues Options

[turnaround89]

The old fuel pump has three inlets/outlets. I was told i could use a new aftermarket fuel pump, however the new fuel pump has and in and an out, how can i hook up the new fuel pump so that it will work with the fuel system? The engine is a 1.8L carbed. Do i have to hook up the return lines back to the fuel tank? thanks everybody.

You can just run the supply line to the carbs and block off the return line. Others have run a pressure regulator with the excess (greater than 5psi if Webers) going back into the return line.

It always seemed to me to be a good idea to keep the fuel flowing through the pump and back to keep it from heating up too much by sitting, and not having the pump feeling the different fuel loads. Probably not a real concern with these low pressures anyway.

You might also consider moving the pump to the location under the tank. Electric fuel pumps like to push fuel much more than try to suck it from far away. What type of fuel pump are you using?
