i have 17 just behind the pcv valve on ± 650 rpm, it is the highest steady vacuum possible, reached wihile adjusting timing and no pinging during acceleration. i have average fuel use 14-15 liter for 100 km = 3.7 usgallon for 62 miles
maybe this info can help _________________ 1942 GPW 71336 my son's jeep restored now

you must adapt the vacuum gauge direct at the intake manifold without with no influence of the vacuumpump on the fuelpump
if you have 15 lbs and the needle is steady everything is OK
eventualy advance the timing a little more to get a bit more vacuum
if the jeep drives fine without hesitating leave it that way _________________ 1942 GPW 71336 my son's jeep restored now
