Question about avoiding rust with metal tank sump I've been searching everywhere on how I want to put my fuel system together and decided to sump my 96 Z tank. Seems simple enough but while reading theres two things I noticed,
1. People are saying to wash the tank out a few times to get the fumes out so it wont go boom. Will washing it out create rust? The last thing I want is to have to replace fuel filters like crazy from rust getting in them.
2. People are also saying after welding you have to find a way to stop the welds and sump from creating rust. Because the welds are on the outside, I'd assume you could just spray some primer and paint on the new sump. But it seems like they are talking about rust on the inside of the sump and welded area. Anyone know if this is true?

Best thing to do is to use some kind of fuel tank sealer. Eastwood makes a kit for that, and I'm pretty sure some aircraft supply places sell some kind of tank sealer. It WILL rust if not treated.
