I completed the same pan work as you.
My new non-high pressure pump runs at those same levels and only in high temps at idle show a lower 45 psi or so.
Was my timing cover leaking before the pump replacement? No. Was the higher pressure a result of a now new leak? I don’t know.
Try Mountain Man Fuel System out of Hackett, AR on EBay.
I just installed their salvaged cruise control linkage stud on my Scottsdale. Good place to start looking.
Jawzjeep,
Could you post a pic of your truck’s cruise control linkage connection that is under the air filter, attached to the carb’s throttle body linkage?
That’s my last piece of the puzzle for my cruise control.
