Bought a running 62 dynamic. The fuel tank was removed and left in the back seat with the fuel sending unit missing. I'm also having trouble with it flooding out.

 

Would Fusick have it?

 

No. Their site does show sending units for various model years and makes, including a fair number of '40s and '50s cars, but nothing for early '60s full-size Oldsmobiles. The only choices are finding a used one from another car or having the non-working one rebuilt, which is apparently not an option for the OP as he doesn't have one at all.
