After getting the tank out, I buffed out some of the rust in the front area since I had more room to work. For nowI just did a shit-quick job of priming that area until I can get it really taken care of (i.e., sandblasted) and painted. In the mean time, I ordered a new tank from Airhead Parts. I thought about cleaning and re-sealing the old one, but it was almost as cheap (they were having a Labor Day sale) to just start over.
Here is the new tank I received, and an "after" pic once I installed it in Orville. I also put in a new fuel sender seal, filler pipe, tank sleeve, and fuel lines. The only thing I didn't replace (and maybe I should have) is the long metal fuel line that runs through the chassis. Maybe after I pull his engine and get him painted.
At the same time, I also replaced Orville's carburetor and generator pulley. I got both those parts from California Pacific JBUGS. The generator pulley also came with a nicer crankshaft pulley, but until the engine comes out of the car, the old one will suffice.
After getting the electrical re-hooked up and adding some gas, Orville fired right up. Chili and I drove him down to Caribou and he was rocking!
