The high pressure injector line coming off the top of the injection pump on my 95' are leaking at idle and while driving, looks like they are leaking right where they screw into the pump. Are there seals or washers in there? How tight should the lines be?

 

same thingh happend to mine they just came loose ... all i did was tighten them snug but not too tight...and im not leakin anymore...so try that and tell ,me what happens.and the nuts on the injector pump youll need a 19 mill wrench

 

Mine did the same thing. Just take them loose, make sure its lined up correctly, and retighten. Solved my leak problem. Use common sense with tighten the line, maybe someone else knows the exact lbs of torque for the wrench.
