Where i see it the most is in a local parade 1st gear for about 3 miles pressure had gotton up to 32 psi. Take it down the road at speed for 20 mins back down to 15psi. What does this? It will on ocassion drop down to 10 or 11 psi but normal is around 15.
Sounds like a Ball Sticking......or pressure spring......OR some restriction on the FASS return line back to the tank. Check the tank Vent? BOTH are very cheap to try to replace....might not hurt to get a fresh spring in that 3 year old unit! Our springs now are way differant than ones back in the day.....lil more robust in design. I would try a PS-1002 (Pressure spring). We also have an updated T-Block that has a pressure releif built in.....this will keep the motor happy if the filter should plug. I love hearing good news rather than "My motor quit". SEE! These old motors still run......just bad news travles faster than good! haha......
