A mahoosive thead revival but I hate to see threads peter-out with no conclusion despite the help of so many. I put a timer-relay in so that the pump relay was cut 15 odd secs after going over to gas. Works fairly well, but the pressure in the fuel rail means I really needed to vent the pressure, else the whole point is negated. So I had the timer relay cut the fuel early so that the engine burns off the pressure instead. Sorta, kinda works.
