Coming home tonight I go on to the skinny pedal pretty heavy. Watched the Fuel pressure drop from 13 psi down to about 7psi. Stayed in it a little longer and looked at the guage again and it had dropped down to 3 psi. Backed out of it and pressure only cam back up to 5 psi. Then I started nursing a little. after a few minutes the guage started bouncing back up to 13 psi and after a couple of miles it was holding steady at 13 psi.
Do you think it is possible to cause enough vacumn in the fuel line to drain the pressure guage line?

LP is on its way out. Some of the same symptoms I recently have dealt with...
