if FPR is original. (fuel pressure reg)
id get a new one.
they cant really cant too good if this old....
if it sticks closed or near, mPG will suffer, when cruising the PFR runs lower fuel pressure and the 02 can go closed loop easy and MPG happens. (at cruise)
the best mpg is. (only happens in 5th gear, i think)
when the speed and MAF sensor curve, crosses. (max speed and lowest air flow) max MPG happens called the sweet spot.
this can be seen easy with any MPG gauge. i think my 5sp was at 45mph, but its best to test each car for its own sweet spot,
hey nice rig, lots of work to make it near new.
way to go....
