        If you are getting Gas' @ the TestPort when the Pump is running then
I would try Clamping the

ReturnHose from PressureReg' to Tank & see if that gives you the
Pressure needed ~ But if that hose is

Old & Rigid BeCareful not to CrackIt ~ If that test works, swap in the
other PressureReg' ~ also make

sure the VacHose to the PressureReg' is in good shape ~

                                                                                        ORR ~ DeanB
