89 GM Fuel Level Sendin Unit

My brother has an 89 GM with 100,000 Miles. It is in excellent condition, looks and drives beautifully. The one problem is that his gas guage doesn't work, and his low fuel light is always on. I haven't been able to find any info on it, and everywhere I look says there is no fuel level sending unit. I am a Chevy guy for the most part, so I am unfamiliar with mercury. I looked for Crown vic and lincoln parts, but nothing has come up. I appreciate any input.

Thsnks a lot

The sending unit is attached to the fuel pump module. It comes as one unit.

ok, thanks a lot

If you search around more, you may be able to find the unit seperately. We swap them from wrecks a lot.
