John as for your line size question you must remember that the line from the mixer to the "0" PRESSURE regulator is primarily a vacuum line! There was not enough vaccum at "cold start" to supply enough fuel for stareting & initial run. It is a concept that messes with mechanics mind all the time. It is what makes LPG carburation so difficult to diagnose for mechanics with carburator & injector experiance! Vaccum Vaccum

Please explain a little more.
Are you saying that
1) Line size doesn't matter, or
2) Since you want more vacuum it would seems a smaller line would pull a higher vacuum quicker (less volume in the line)? IF this is true, I would assume you wouldn't want the line's i.d. any smaller than the carb orifice (3/16" in my case)?
By the way - another question! In my initial installation, the regulator was in a vertical plane, but rotated with the outlet at about 10-11 o'clock position and the engine seemed to start better then. Now, in the present mounting position, the regulator is still in a vertical plane, but the outlet is at 9 o'clock. The PNG Technologies tech said the outlet should be at 12 o'clock/straight up, but I noticed that several pictures of installs in this thread have the regulator rotated over to 9 o'clock. Do you think this makes any effect on regulator function???

John
