Aux Fuel Level Switch 804A

Anyone have a source for the Aux fuel level switch on the 804A? Madison Co M3465

The plastic base on mine broke and fuel leaks everywhere when tank is filled.
GM shows backordered.

Reach out to these firms, see if they can help you directly:

https://www.gemssensors.com (part number 134230)
https://www.madisonco.com (part number M3465)
https://www.shawdev.com/index.html (part number 10455-1)

And I don't know for sure, but GMG shows a part number also of 88-21121. That relates back to an auction on the big auction site with the heading "NEW Fuel level sender sending unit M3466 134240 10455-2 88-21121 2910-01-391-636".

Its a different NSN listed, but they do include that same 88 number. I am sure you can take measurement and ask the seller questions if need be.

Could you repair it with some JB Weld?

Let me poke through the shop, I think I tossed a dead fuel level switch of an 802. Its probably got that same plastic mounting base. If I still have it, I'd be happy to send you that part.

Thanks, that would be awesome! The rest of it doesn't look it's in bad shape at all.

Thanks, that thought did run through my head, but I've not tried epoxy on plastic with diesel.

Works like a charm.

I found the part. If you still want it, send me a PM with your address and its yours.
