ok, drivers side of engine, front, beind the acc bracket yet in front of how low the exh. manifold goes, is a tap point for the electric L-N O R M A L-H gauge, which most F series XL and above had (in fact I think it was std)
rip it out, put in a 1-1.5" 1/8th npt nipple and a 1/8x3 T, and in 1 end a 1/8 npt street elbow. put the ford thing back in and plumb in a sunpro (or whatever) mechanical gauge.
On the dash, if you do not have the dash mounted 4x4 switch, is a removable 4x6" panel that will take a 2" hole saw for the bezel.
route any wires or lines away from the exhaust mainfold.
I dont have any manuals in front of me, but I seem to recall the requirement is 35+psi at 2K rpm (my original 1990 ran 52 when I cut her up and the 'new' 1990 does 49-50 but I dont know how it was taken care of for its PO's 140K miles) - any chilton book will have the spec, mebbe someone reading has one handy
the 10psi/1Krpm is 'yunnicks rule of thumb' and works for SBC but its also based on a racing motor that is gonna STAY up there, if my chevy cars were cruising in OD at 15psi at 1500rpm on the highway, Id be adding parts....
