When (if?) I ever get around to fixing it, I'd be glad to take some pics.  But honestly, it could be a long time before I do fix it.  If I filled the tank and drove it the average of 18 miles per year, the fuel gauge doesn't become a problem for over a decade

So don't wait on me to fix mine, or you might be calling AAA for a tow now and then ... And we wouldn't want that!

One thing you may need to consider is, that tank has a "bladder" in it. They are known to deform over time, and can/will hang the float for the gauge.
The main part of the bladder can be removed if it is damaged, but it is also the seal for the sender unit/tank. You can cut the top part of the bladder off, where it goes around the hole, and use it as the gasket for the sender.
They do not make a gasket for this tank, so you're pretty much stuck with using part of the bladder, or using a thick cork gasket material, and making your own.

Joel..... I beleive corvette central now carries the gasket for the sending unit, I'm at work and not at home but I just got a gasket from them for the sending unit or I'd give the PN for the gasket. You are right a few years ago you had to make you're own gasket.

Thanx for that info, Steve!

Mike,
With only original 450 miles, you need to either keep the tank topped off to keep the air out or drain the entire system to keep everything from getting varnished.
But remember, Vettes were built to be driven.
