[QUOTE="EMD_Driver, post: 87891, member: 2185"] Thanks John... Finally figured out and it wasn't the pump, or the regulator. I replaced everything from the tank to the heads, with the exception of the fuel bowl. Since the regulator had a plugged port readily available, I put a barbed fitting in it and Tee'd off the supply line from the pump. I now have 55PSI at idle and no less than 45PSI at WOT (On my 80hp tune) I haven't tried it with the stock tune yet.. I have an upgrade planned, for the supply lines to the heads.. I used 1/4" steel line originally and plan on upgrading to 5/16" and deleting the fuel bowl. Depending on how things go in the winter, I may add a 12V fuel heater. [/QUOTE]
