Low Fuel Light Always On

[GRSHOPR]

Ok, so I'm in the middle of converting all my lighting to LED, and I used one of the prefab 34 socket red bulb replacements from Super Bright LEDs, and I KNOW my gas gauge is accurately reading low, but the light isn't coming on. So I flip it around, because of course, diodes are unidirectional, but now it stays on all the time, and I just filled up my gas tank. Anyone got any insight into what the heck is going on?

Mine is on all the time too... but I have a dual pump setup. Still, curious what will be recommended.

Bump, I'm lost

You're probably going to end up needing to add a resistor. This is probably something like "hyperflash" that is experienced with turn signals.

If you have regular stock gauge cluster bulbs, then it's the wire that wraps around the rod for the reserve sensor. It has insulation worn off and is grounding on the rod. Super easy to screw up when installing the pump assembly into the tank. It happens fairly often.

I've done exactly that. Easy fix, just annoying.

Actually, it has a resistor wired in already. Hence my confusion.

UPDATE: Brian, you rock. With that info, I was able to get further answers. Thank you! I've ordered a load resistor that I hope will work, and go from there. Thanks!

I had that problem and it is exactly as Hans said. The wire that wraps around the metal rod that hold the low fuel sensor on the fuel hat got stripped and shorted to the rod. I re-insulated the wire and all was good again.

That's for future, I suspect. I haven't even looked at the fuel pump, let alone touch it, so I'm going to try Brian's suggestion. Future, did that fix your issue?
