I have heard, I think it was Andrew, talk of moving the pump bracket to adjust belt tracking??
I cannot for the life of me remember what thread it was in, or what section.. I ask because my belt is slightly tracking towards the passenger side and very slightly rubbing on the outer edge of the tensioner lip and the lip on the reversed spinning pulley. Little annoying squeak, squeak, squeak at idle before it warms up

how do i remedy this?
I've had all kinds of trouble with tracking before, it can be very frustrating!
Yours doesn't sound too bad, but one thing that has worked for me is a thin washer under the pump mount bracket that bolts to the block. I put it between the bracket and the block of the bolt nearer the belt. This twisted the bracket just enough to keep the belt tracking in the middle of the injection pump sheave on my engine.
