Okay, so last week the car starting running crappy. checked the fuel pressure, was jumping around then dropped to 0(I have carbs running at 3lbs). So yesterday I installed my brand new back up pump. I was tunning the carbs, everything was going great. After 20mins the car start running crappy again, look at the fuel pressure it was doing the same thing again. Car died, fuel pump wasn't making any noise, checked and it was flaming hot! I have a primary and secondary fuel filter both are clean. Called Mallory they said it must be a bad pump, send it back. Fine, so overnight a new pump install it, this time checking it often. It starts getting hot, what the flip! I can hear the pump changing in pitch, so I think must be elec. I'm getting 13.5v at the pump. My volt reg is rather hot so I put in a new one, now I'm getting 14.2v at the pump. Still getting hot, change the relay( it was hot also) still getting hot!
some pics of the set up. Any suggestions? Attached image(s) ![]() ![]() |

Heat means more work than expected, more DC power supplied than expected, too small of a power line, or a failing motor.
Gotta load of crap gas? I had a Vanagon take on about 3/4 of an inch of crud in the bottom of the gas tank in one fillup. Pump motor heated up and whined due to excess work pulling through the filter. Took over 45 mins at the car wash to finally blow out all of the crap. That was when our ever faithful oil companies knew they had screwed up the gas mix so it would ruin the fuel tank sensors and shipped it anyway. Can you rig up a bypass and pump the the gas right back into the tank filler without heating up the pump? If you can, the problem is between the pump and the carbs. Ken |
