Anyone know offhand what static psi the 87 GN ran with the stock fpr?

i am sort of new to the GN game too, but i believe it was 37-38psi.

I think it was closer to 33 with the stock regulator (-233) and 37 with the TTA or Somerset FP regulator (-237 Bosch part number). Anyone agree?

When in doubt- whip it out- the shop manual, that is. Per Chart A-7, Fuel System Pressure Test, pressure should be 34 to 40 psi (234-276 kPa) That's with engine not running, so the hose doesn't matter.
