bignum Posted April 25, 2008 Share Posted April 25, 2008 After fitting my aeromotive fpr and finally getting the pump running i decided to test the fpr against a vacuum/ pressure source so this is what i did. Got the pump running static @ 40 psi then connected a digital tyre pump to the pressure input on the fpr to check 1;1 ratio pressure rise and hey presto i could hear a hissing and fuel pressure not building as it should, so got some fairy liquid/water mixed and put some around the fpr only to find air leaking out of the top, where you adjust the base pressure, so i sealed it with some universal blue gasket stuff and now get an exact 1;1 pressure rise, so if yours is leaking unless you have an in car pressure gauge you might only be getting 1;0.5 rise and not know.
