Fuel pump overheating, help

Fuel pump overheating, help
I installed a Holley 125 electric fuel pump behind the passenger seat. I took out the in-tank pump and installed a rubber line for a pick-up. I think it is overheating because of lack of fuel flow. Has anyone else run into this problem with their pump overheating and stopping? I am going to install a return line but I was told that it would not be necessary but I think that if I do not the pump will keep quiting on me.

Re: Fuel pump overheating, help
i am under the impression that you are required to use a return line with an electric pump.

You really need a return line, if not then the pump sits there trying to pump and nothing is moving. Especially on a carb setup. Most of the ones I've seen are mounted under the car where they can get cooled slightly by the wind blowing through. That might help as well.

I would think that it would be better to keep all of your fuel lines on the outside of the car. Maybe mounting it near where the stock fuel filter location would be, just in front of the rear tire.

You also need to keep in mind that the pump should be no more than 36 inches from the tank MAX. If its too far away it will have a hard time---its designed to push fuel not pull it. A good drop in elevation from pickup to pump will help too. As stated above a return style regulator is ALWAYS in order.
