Two weeks ago I installed my brand new FASS 150/150. No problems at all, and I only had to start it twice to get the air bled out, sweet. I left work late last night and my fuel pressure gage was fluctuating between 5-15 psi. It seemed to get lower when i tromped on it. My truck does have a larger siphon tube, I have verified 12V present, filters are new as of two weeks, and my tank is clean. No water in my fuel, and it wasn't cold enough to gel last night. How is the pressure regulated in the FASS is there something easy to check?
If you have the suction tube kit, how low was your tank? If you were about 1/4, the fuel can slosh away from the tube and suck air. I suggest that if you are going to do any daily stop-and-go driving, try to keep fuel levels about 2/5's or more. This will keep this from happening. Now on road trips on the hwy, you can run the tank down lower since you are not sloshing the fuel as much.

Let me know what you find.
