    Default ZR-1 Fuel sending unit and fuel pumps needed

    Good day,
    Help needed I have a 1990 ZR1 that does not run and no fuel pressure, I discovered after taking the car apart the fuel pumps are shot and the sending unit is so corroded due to ethenol fuel deteriorating the unit. I am trying to locate replacement parts but no such luck. I was wondering if anyone else has experienced this issue and also can a standard fuel sending unit from a standard L98 base car be retrofitted to work on the ZR1. Any help would be appreciated.

    To the best of my knowledge, no.

    You may want to contact Lingenfelter. They have a direct replacement for the ZR-1 fuel pump assemblies:

    Yes I did buy the replacement pumps, in fact I bought 2 kits because I have two cars. However you do not get what the picture shows, you get two pumps, strainer filters and some hardware. I need a sending unit that is completely shot and will not function. I did some research and got a few ideas to get things working again. I am just glad my other car is still running and the fuel gauge works

    Thanks for your input and assistance.

    Okay, I'm confused, you state: "I need a sending unit that is completely shot and will not function." Is that a typo or are you looking for one that can be rebuilt or are you looking for a new replacement? If so, would this work? Corvette Gas Tank Sending Unit, With Pump, ZR1, AC Delco, 1990-1995

    I don't like making plans for the day. The word "premeditated" is not useful when it gets thrown around a courtroom.

    Thank you very much for the link. My sending unit is shot and I bought 2 new pumps to install on the current fuel pump assembly. This will help out with a direct replacement.

    I think I'd call that vendor and ask them to confirm they actually have stock of that part (ACDelco PN 19180770) before I'd place an order.

    Hello Snapper, I am a new member. I just bought a 1990 ZR-1 about 2 months ago and had the same exact problem. My sending unit was completely disintegrated into the t fuel tank. The car had been sitting for 4 or 5 years. I lucked out and found a complete sending unit on ebay from a 1994 ZR-1, I chose to clean my tank, installed new fuel pumps on the sending unit and have it installed. Maybe you could check on the Net. Registry in parts for sale, I don't think a L98 unit will work, I'm new to these cars and am learning, I paid 400 bucks for the part. Good luck, I will keep my eyes open, if I were you I would check every Corvette site regularly you never know when one will come up for sale.
