A new >pressure regulator is $70 and i would like not to just throw $ at the >potential problem. The regulator is supposed to supply 2.5 bar (36 psi) over manifold pressure. If it supplies 10% more than this, the injectors will supply 10% more fuel than expected. The ECU will attempt to compensate by reading the O2 sensor, but if its compensation ability is exceeded the motor will run rich.

But for a start, stick your gauge in an evacuated bell jar with the gauge inlet vented to outside air -- you should read about 14.5 psig with pressure of 1 torr or so. I presume that you have access to that sort of thing...

No. Normal (in small quantities) AFAIK. david David Beierl - Providence, RI http://pws.prserv.net/synergy/Vanagon/ '84 Westy "Dutiful Passage" '85 GL "Poor Relation" |
