My adjustable fuel pressure regulator is leaking all over the place. When I tighten the bolts on the regulator, the rail leaks, when I tighten the bolts on the rail, the regulator leaks. Its an obx, so that might have something to do with it, but any installation tips would be nice because I have to drive tomorrow. How can I stop the leaks? This regulator has a guage.

 

Did you only buy the regulator or the regulator and rail?

 

did you use teflon tape on the bolt threads? Did you just buy this or have you had it a while? Have you tried replacing the O-rings?
