I'm planning to refurb our fuel tank this trip. Should a fuel tank be pressure tested? If so, how the heck do I do that? This is a 914-6 carburetor car, if it matters.
It is out of the car and appears to be in very good shape. It hasn't had anything in it for many years. I would love to think there is some high tech copper coating in the bottom, but I suspect that is surface rust. I am thinking that a couple gallons of Evapo-rust for a few days will solve that. Also provide some evidence if there are major leaks. Then probably fog it with Sea Foam, since it will probably be months before it's actually attached to the engine. Anything I'm missing before it would go back in the car?  |
