Fuel pressure regulator

[dboisen]

Working on a 89 xj with 4.0 and I have a fuel leak where the fuel pressure regulator connects to the fuel rail. Anybody know if that oring is the same as an injector oring?

Yes it is, same as the black injector o-ring.

Make sure the little white rings are in position also.
