Fuel pump runs continuously, PO rewire Options

[rjames]

When removing the gas tank for a sway bar install I noticed that the fuel pump on my '75 had a different colored wire hooked up to it, and a stray wire not going to anything. It has always worked fine, so I ignored it.
Then I learned that the fuel pump is supposed to shut itself off after a few seconds with the key in the 'on' position.

Mine doesn't do that, it just runs continuously. While I do want undo whatever the PO did and wire it correctly, I don't have time to do anything now. My questions is will this hurt anything assuming I actually start the car and don't just leave the ignition in the position without it running?

Thanks-

I just went through this, maybe not the same situation as yours but same year.


I brought the car home and the PO had rewired the fuel pump to run contiuously while the ignition was on. He also installed nifty push button switch. The original wiring was left intact fortunately.

The BIG problem I saw was that the old lines could not handle the load , not sure if it was just the age of the lines or the pressure, but they were leaking pretty good.

Another problem that crossed my mind was the old wiring was left intact and could have possibly been live, not the best thing to have under a leaking tank.

It was fixed in a matter of an hour or two.

My vote is to fix it and forget it.

BTW
The reason the fuel pump wasn't working is because of a bad dual relay (1.8L L-jet)
