I have an injector pump that the diesel service turned up for me when I bought it. I installed it when I put on my banks turbo.I ended up cracking all my main webs and had to replace the motor.I bouught a used 82na 4x4 supposedly rebuilt and swapped the motor,50,000+ later a head gasket went, replaced both gaskets with 6.5's and now my i.p. pump is slightly leaking.I want to replace it with the turned up pump but I don't know how much they turned it up and I have never adjusted one so I don't know how to turn it back down for a na.It's the weekend and they are 300+ miles from me and closed.Can anyone help me out with how to go about this?
