30 inches, is wrong. so is 45inches. 45 inches of Hg mercury column vacuum is impossible on( the Vac gauge is RELAtiVe VACUUM,NOT ABSOLUTE)
Please post PSI fuel pressure , and vacuum in the Plenum in inches of Hg. together.
your injectors are super over injecting so the engine floods, and fouls spark plugs but we know why, the fuel pressure is dead wrong.
and too high.
vacuum is never 30, ever.why do you tell this? is your gague wrong or is the gauge only in KPA (metric)
yes the return line flows full time running engine at speed and any hill on earth.
if the return line is blocked the fuel pressure goes sky high (wrong) .
that carquest fpr should be Ok
Got the new FPR on last night, 40 psi key on 40 psi idle, 40 at idle is dead wrong. 18PSI too high
38 psi during acceleration but still bogs and runs worse than it did before.
all this is wrong,dead wrong.
the reason i can answer is the lack of vacuum at each PSI fuel pressure stated. (use a 50cent vacuum TREE fiittng)
or remove the vacuum hose on the pleanum tank, front brass nipple, going to evap VSV electric valve.
this must suck air if running, if not clean this nipple first.
now with vacuum gauge Inches of Hg,mercury gage (usa use Mercury Hg vacuum) the rest of the world uses BAR, do not post BAR readings or KPA,here.
now with that fitted, to evap nipple
the vacuum readings can be done easy and fuel pressure at the same time.
can you post a photo of your vacuum gauge and PSI fuel gauge.
as you can see there is no 45inches of vacuum possible on earth.
when the engine going fast down hill, and you lift right foot, in lower gears the engine is huge vacauum pump and can hit 26 " or more\
but 45 is not possible.
