Today I had to drain stale gas from a black 66cc gas tank. I removed the fuel line from the carb and held it over a gas can. When I turned on the brass petcock, no fuel came out. There was plenty of gas in the tank. I turned the petcock all the way open and around, trying to find a sweet spot, none was there. I tried this with the gas cap on and off with the same results. I ended up siphoning fuel with my mouth and a rubber hose. I've heard there is a screen filter on the inside of these petcocks that are tiny to begin with and probably also clogged. My plan is to remove this bottleneck entirely by removing the screen and replacing with an inline visu-filter.
How do you remove the petcock from the tank? How exactly is the petcock attached to the inside of the tank? Those little moist pink gaskets look pretty fragile, is it possible to re-attach them later on without breaking them? How do I do this?
How difficult is it to do the 1/8" NPT petcock, is this advised or should I stay with the original setup? I've never worked on these before.
