Sending unit part number help

[blackbuck350]

Hey guys I’m replacing my fuel tank-sending unit , does any one know the part number for the sending unit, all local part stores says they are unavailable. Had one delivered and the pick u tube is too short. It going into a 81 Malibu wagon. Any help would be appreciated

Wagon sending units are not repro'd and NOS ones go for stupid money.

I'd suggest buying a sedan/coupe version and modify as required for correct depth.

2 line or 3 line? Does it have vapor return line or no?
Best I can come up with for 69 Litre wagon tanks:
25000757 for 2 line, without vapor return, V8 and 3.8
25000758 for 3 line, with vapor return.- has black ground wire.
There's also a 25000760 for4.3 w/vapor line (3 line)- has blue ground wire.

NO idea what, if any, are the differences.

This could be off, so take it with a grain of salt.

If you need to get a coupe/sedan version to modify, use the applicable version below or equivalent. They're out there nearly everywhere.

25001612 for Coupe 2 line - black ground wire
25001613 for Coupe 3 line - black ground wire

if you can only find 3 port and you only need 2 you can plug the retun port

That's for an electric pump, and the Astro tanks are just shy of 1" shallower than the G wagon tank.

Would work, but again, more mods.

So do you guys think the FG18b will work or do I just need to modify the one they sent? Because I have to have at least 12 gallons of fuel before it picks up fuel
