I installed a fuel lab fpr a couple days ago. I set it at 43.5 psi with the vac line removed. Today I was looking at it and its at 43 psi with the line on. I then took the vac line off and the pressure did not change at all. So basically the pressure stays the same with the vac line on or off. How should I adjust it then?
