Craig;

...do I need some sort of therapy if I say that I think those pix are sexy?...

From memory, there have been other threads (of dissapointment) long ago about that type of reg...those FPRs are just not very reliable...unfortunately, if it lets you down, with leaks from itself or overpressure causing leakage from the carbs, the immediate results could be disastrous...I've always wondered if a proper, quality, bypass regulator like that used on the D-Jetronic could be adjusted down to the minimal pressure required for the SUs... 2PSI max is probably just too far from its intended operating range without changing its spring...

Cheers
