I have a 98 SVT Contour. I just installed a VDO 80 PSI elec. gauge in the a pillar and 80 psi elec. sender in the head (behind the throttle plate). I am getting readings of 75-80 PSI During startup with no decrease in pressure. (I also have a small leak from around the sender)
I am using 10-40 Mobil 1 (3000 miles on oil), a Fram Extraguard filter. What should the PSI be (I am assuming it should be around 30-45)?
