I could use similar help. I have been playing with mine for sometime, and it looks like the anti-siphon was not preventing the fuel from draining back into the tank. I changed the Anit-siphon valve, but still concerned what is the line is dry. My fuel pump does not come on with the key, but does come on with the ignition. Is there something wrong with my relay or one of the diodes?
