Thankfully, the gas tank should be serviceable; not so much for the fuel sending unit. The fuel gauge had been working somewhat, but never quite made it to full position. I found two problems: the float had some liquid in it and the contact arm was worn-through.
Prior to disassebly, full position read 44 ohms, and empty (at the stop) 233. The book specs 16-22 ohms at full and around 250 at empty (from memory). I tried to cut off and bend the contact arm and then it was totally ruined. Shopping for a replacement!
I will use the mounting flange from this one, to hold the rebar / insulator to the tank during cleaning.

Normal wear, I guess |
