I looked all over the internet for a 91-92 comanche sending unit. I never was able to find one. I was buying some other stuff at Autozone and the guy asked me if I needed anything else. Just joking around I said not unless you can get me a fuel sending unit for a 91 or 92 comanche. He looked it up and had it in stock. It is a delphi pump and sending unit combo. It is a little different than original but it works great. Fuel gauge reads real accurate. It comes with a delphi pump. I would recommend throwing that away because it is noisy as hell. My jeep sounds like an s10 with that annoying fuel pump hum. No modifications needed just set it in and your gauge will be accurate for 79.99. Now the Ho swap is basically done and everything is working. I forgot to grab the part number but, i will post that up later for you.
