I'm going to rebuild it
But wanted to know if anyone had put on an adjustable spring and fuel pressure gauge to adjust fuel pressure.

Check for vacuum leaks before spending money on the throttle body.

I have an adjustable fpr but it's hidden down on the frame, not up on tb like most.

It could just be a leaking throttle body mounting gasket, it happens a lot.

Will do
I plan on replacing ALL hoses when it warms up.
I'm itching to play!!!!
The parts are piling up!!!

Any suggestions on a good repair manual
All the ones I have found don't show ANYTHING for a V2500
