Message	Mine would rise to ~40 psi and fall to about 10, then slowly 0. In order to test that it was the pump return, I put some vice-grips on the return line and primed the car. It went to 40psi and stayed. But for some reason, after I removed the vice-grips, I didnt have the issue any more. Im assuming it broke something free and it started working again ------------------------------------------------------------------ 1992 300ZX NA 5 Sp (Dead) 1990 300ZX NA Auto 2+2 (Dead) 1990 300ZX TT 5 Sp (Stock Turbos) (Est. 400 HP) 1990 300ZX TT 5 Sp (GT600R) (Est. 600 HP) 2004 G35 Sport 6MT (DD) 2008 Honda Civic (DD) 2014 Nissan Murano (DD) 1969 Chevy C10 (Toy) 1969 Chevelle (Toy)
