My next door nieghbor ame home with a real "Barn Find" He semi inherited it or swapped for an RV, or whatever. Anyway its a 1952 MG TD, been covered for 35 years with 35,000 miles on it. Not for me but a neat find non the less. It cranks over, fuel pump disconnected. My question, the gas tank was drained at some point however it does appear to have rust in it. So my question, we have to start here, do I pull tank, flush and coat with the Eastwood, Creme stuff? Replace it or just rinse it with some kind of solvent. I hate to get this running and have ongoing fuel issues. What would you do?
