#1 Fuse Overheating 700 1985

Main fuel pump fuse getting hot. I do have the whirling noise with less than a quarter tank. I have read the FAQs ref this and plan on pulling the intank pump and checking the short hose. Would this hose leaking put undue stress on the main pump causing it to draw a lot of current?

#1 Fuse Overheating 700 1985

Aleecat,
open fuel path will not cause the pump to have increased current draw requirement, actually, just the opposite. ALL motors have start up resistance that must be overcome. All motors draw higher current at start up than while running.

More than likely the contacts to the fuse or relay have become corroded or oxidised. a poor connection will cause heat as a byproduct. The best way to keep cool is keep the contacts clean. Use electrical contact cleaner. It comes in a spray or a liquid that you have to apply.

It may also be that your fuel pump relay itself is causing added current draw through the fuse, as the relays are always a prime candidate for the owl solder gun technique so many rave about.

You didn't say anything about your secondary fuel pump making excessive noise, wich would rule out a grounded main fuel pump.

Good luck, hope this helps

Thanks, the in tank pump works, testing via pulling the fuse.. Resoldered the relay. Replaced the #1 Fuse line with an inline. Next step will be the short hose and fuel sock. See if that helps. I have no running problems, just the extra noise.
