Fuel Pressure Regulator

[kcoyner]

I have a fuel leak at the fuel pressure regulator. While I'm at it, I decided to go ahead and do the spring upgrade. Anyone know the torque spec for the 4 screws that hold the cover on?

Thanks!

The service manual does not list a torque specification for the fuel pressure regulator cover bolts. Do not over-tighten or you may crack the housing. Just lightly snug them up and use blue locktite.

I checked AllData, the only torque spec it has is for the fuel return tube. That is 43Nm(32lb.ft.). I just snugged mine up.

As a good guide and based on the size of the screws, 2 ft lbs (24 in lbs) would be more than enough for the screws.
