Is this the correct sending unit?
I ordered a sending unit for my 1990 ZR-1 last November. I was hoping to put it in during my Christmas break. My fuel gauge is way off and I didn't want to mess with opening up the old one and trying to clean the contacts, etc, and the replacement unit was a good price.
It just arrived and I won't have a chance to look at this for a few weeks, but ... is this the correct sending unit?  I know we have two fuel pumps, but there's only one electrical connector. Since I haven't removed the old one, I don't know if this is the correct part or not. Does anyone know? Thanks

Re: Is this the correct sending unit?
I think you nailed it. One connector, one pump.

I concur with Jerry it appears to be the correct pump and sending unit

And, the photo of the unit Jerry linked to has 4 wires on the flat connector; black, red, gray, green. The one in ghlkal's photo has only 3 wires; a ground plus one for the (single) pump, and one for the sending unit? ghlkal's is a single pump unit - or so it appears t me. No? P.

Mine has two connectors total, but only one for the pump. The other connector you see there is for the wiring harness. And as Paul noted that connector only has three wires (black, gray, purple) and I assume I need 4. Darn ... Thanks for your help guys.

Re: Is this the correct sending unit?
Sorry, I should have worded my reply better. I tend to be less "wordy" when I'm on my phone.
YES, 2 connectors to the pumps, 1/pump. Other connector plugs in to harness.
