Hi Pantera Doug, Thanks for your input. I have the pump installed correctly; input from the fuel tank line, output headed to mechanical pump. I've run the fuel tank to below 1/4 level and never a problem with engine running. I'm still perplexed on how the electric pump pulls fuel from tank line then pushes through the mechanical pump up to carb...? Max 4.5 PSI doesn't seem enough to do that when actual output is probably only couple pound. I have not put a fuel pressure gauge on the system to test.. Thanks again, Ron
