I have a volvo 5.7 gipmda. The one with two fuel pumps. One on the front of the engine directly above the fuel filter and one at the back of the manifold mounted horizontally.the one I am interested in is the one at the back the high pressure one. I took fuel pressure readings today and got 6 psi on the front pump and 18 psi on the back or high pressure pump. Do these pressures sound correct or is the high pressure low? Thanks in advance.
