Barn Find…sort of… non-Mopar

Working on getting the ‘54 Chevy running. The Rochester carb was totally gummed up from alcohol gas that had evaporated. Rebuilt the carb and learned that rebuilding an old Carter B&B carb (Mopar) is much easier.

The old gas in the tank stunk like turpentine and was the color and viscosity of varnish. Berryman B-12 has really helped clean that mess.

The fuel pump was totally seized, got a new one. The fuel tank to fuel pump was plugged.

Disconnected the line from the tank. Could not blow air through it. Got Berryman B-12 in the line for a couple of days, then it blew through.

However, the pick up tube in the tank is plugged. Ran a wire down it, no luck. If the B-12 doesn’t open it up soon, I will be pulling the tank - not what I want to do.

Does anyone know if this intake line is just a tube, or does it have a filter on the end? If I pull the tank, I will pull the sending unit and probably replace it. This will give me a 3” opening to really slosh cleaner inside and try the pressure washer.
Do they not make new fuel tanks for it?
