View Full Version : Fluctuation Supply Pressure

12-02-2009, 02:18 PM
A few months ago I installed an AD150 with Vulcan Draw StrawI. Ever since then my fuel supply pressure fluctuates from about 15psi and then it will jump up to sometimes 17psi and then maybe jump back down to say 14psi. It never goes lower then 14psi, even at WOT, and it doesn't fluctuate continuously. Some times it will sit at 15-16psi for a while then jump. What could be going on here? I know there is some air in the line for my fuel pressure gauge.
