Abstract: my '63 AFB carb's automatic choke heater pipe is clogged. Gas tank has interior rust. Best path to clean/replace? My '63's R-1 engine had recently been having a dickens of a time lighting up and staying lit. The vacuum seemed ok, so I took the car to a carb shop that advertises in the local SDC chapter's newsletter. They noticed a couple of things: 1) rust coming in through the fuel system, and 2) the heater tube for the automatic choke was blocked. The choke thermostatic spring was apparently incorrect, and replaced. Issue #1 rust in fuel: I'm going to address it with a replacement tank, and a new fuel sender while I'm at it, the gas gauge never having read more than half full on my watch. I'll test the gauge too. Studebaker Intl's replacement tank is apparently aluminum, which even if not coated inside I'm thinking will do better with current fuel than steel. Based on my experience cleaning rust from surfaces I have full access to, I don't see any value in attempting to clean and re-seal the current steel tank. Issue #2 clogged choke heater: The '63 parts catalog (page 29) shows p/n 1557420 Pipe, Automatic choke heater. As you'll likely know, the bugger is a metal loop plugged into the intake manifold. The part isn't in stock with either Studebaker International or Stephen Allen's (mystudebaker dot com). Unless I can run a pipe cleaning brush through both the rubbish in the pipe and the sharp bend in the loop (not likely), I'm going to have to remove the manifold and tap the thing out from behind to remove and deal with. I pray the crap in the pipe isn't due to a hole. Questions: How have you cleaned or obtained a replacement choke heater pipe? Or, do most people ditch the original automatic choke for an electric? Should I bother sealing the aluminum gas tank? I was considering Caswell's gas tank sealer.
