You won't find one, at least not new, unless you get lucky on ebay, but then you'll pay a small fortune for it. My '67 Delta 88 uses the same sender, and when I needed a replacement, I found that a sender that fits early '70s Buicks and Oldsmobiles would work.

Specifically, you want Spectra Premium part number FG-106A, $50 at Rockauto and probably available through any auto parts store at who knows what price.

 

 

You Could also send yours out to get rebuilt

 

 

Yes, it does, because the tank is not baffled as the canister acted to dampen the fuel sloshing effect on the sender's float. But is the glass half full or half empty? The replacement sending unit still indicates how much gas is in the tank, and that's a heck of a lot better than no gas gauge at all.

 

 

That is the fuel sending unit I used in my 71 98. Here's a thread on when I installed it:

The build quality of those sending units is pathetic. As I stated in the last post of the thread I linked, the fuel sending unit signal wire stud grounded against the body of the car with the tank installed. This caused my gas gauge to constantly read E. I was able to fix the problem by drilling out the stud and using a machine screw to attach the signal wire.
