After driving awhile and engine off with key in the on position , my fuel pump (walbro) won't shut off after priming. It just continues to run even after what seems to be the relay shutting off (that satisfying click). When cold it primes and shuts off as it should. I threw on another regulator (stock) and same ----. Oh yeah its an ls. Anyone experienced this before?
