I would try to contact these guys. He will sell you the gas tank separately or at least he was going to last year when I wanted one, then found out I did not need one.

This was already answered but reminded me.
When I did the first fuel pump replacement on mine in 99
I cut a slit up the filler tube to within an inch of the top of the tank.
Mine now takes 21gal to fill

I'm not sure if Corvette Recycling is the same tank as Corvette Central, but some type of new design without the darn bladder that collapses:

John,

I thought I had a problem with #17 below and my gauge was always off, but I discovered it was just the float on the sending unit that was deteriorated and not really floating. I could not replace just the float so I had to replace the entire assembly.

If I had to replace my tank I would want to get one of the new designs from Corvette Central without the bladder.

7. TITLE - 18 gallon fuel tanks


YEAR(S) - '93-'95



PROBLEM - Near the end of 1993 GM found themselves with a weight problem on the 1993 ZR-1. To meet the same EPA class GM had to come up with a way to cut some weight off the '93 ZR-1. They did this by installing a rubber extension on the fuel filler pipe to limit the fuel capacity to 18 gallons. The fuel level float arm was also adjusted to reflect the 18 gallon capacity. All 1994 and 1995 ZR-1's were suppose to once again have 20 gallon fuel tanks. But some owners may find that their reserve light comes on before other '94 and '95 owners but take the same amount of fuel. The problem seems to be that the fuel level float arm that was adjusted for the '93 may not of been re-adjusted for the '94's and '95's



CORRECTION - The tank sender and fuel pumps can be removed and recalibrated (90 Ohms produces a full gauge reading and 0 Ohms reads empty). A new gasket will be needed to complete the repair.

SERVICE BULLETIN/RECALL - No


17. TITLE - Fuel tank doesn't hold 20 gallons.


YEAR(S) - All



PROBLEM - When you go and fill up your fuel tank even though the gas gage reads empty, your tank takes less than 20 gallons.



CORRECTION - There is what is called a "bladder" inside the fuel tank. This bladder is not pliable but a rigid black plastic. What can and does happen is this plastic liner pulls away from the fuel tank walls causing bulges or bubbles. These bulges can shrink the size of the liner and therefore reduce the capacity of the fuel tank. The only correction is to replace the fuel tank. Thanks to the ZR-1 Registry, Dennis Gratton and Jim Ingle for this information.



SERVICE BULLETIN/RECALL - No
