I picked up a fuel pressure gauge today at the local harbor freight and connected to the fuel rail. Wow! over 60 psi. Luckily, I haven't driven much since I have recently put the engine back in after replacing fuel lines, seals etc. This is a 1.7L d-jet system. I loosened the adjustment screw and nut, which took quite a bit of force. I made some adjustment and tightened the lock nut. Then turned the key to run the fuel pump and the adjustment screw now leaks. I haven't actually started the car because of the obvious problem. Now I've taken the regulator out to have a closer look. It looks like the cone end of the screw seats against a diaphragm inside the unit. Is that right? Why would it now be leaking?
