If there was a real reason to install a separate vacuum port just for a MAP sensor, surely they would have said why , but they didn't. Basically it should be close to a throttle body, where the factory port usually is. Also the shorter the lines the better. Smaller diameter, also better, i use 3.2mm silicone hoses. Basically vacuum should read ~0.3 engine idling, ~0.9 engine off meaning atmospheric pressure.
Yeah, I don't really understand why teeing in is a problem but the stag guide says to add a new takeoff so I guess there must be a reason. When I spoke with the inspector he said they always add a new point on their conversions but he didn't explain why. This was filmed a few months ago but I note your point on the silicone hoses, I would definitely use those in the future, I just hadn't thought to before. I suspect this will be my last LPG conversion though.
Nice job, surrounded by gaz and gasoline in a tin can with wheels, I thought I was brave doing 90mph in mine but you are next level...
