Fuel pressure
Hi I have just repaired my power stering pump it was leaking from the seals and I replaced them but know my fuel pressure guage it's reading at 8 psi and it was reading before at 13psi does any body know why it change I am worryed because it's geting close to 5psi .I have just replaced the vp44 with one of blue chips also I put an airdog 100 and a dpricol fuel preassure guage with an isolator wich iam thinking of takeing off and replacing it with a needle shutoff . Also I been running the truck for about 1800 miles and also the last 1000 miles I have been driveing it in Mexico and the diesel here it's very nasty it has alot of trash in it . Thanks !

Most likely it's the isolator. It can be reset by removing the gauge side fitting, pushing the diaphragm down tot he engine side with a pencil eraser and reinstalling.
I don't like the pancake style isolators. We have only had 3 failures with our type with thousands sold!
I also do not like the needle valve. I have seen a few fail and it's an impossible fix on the side of the road.
