I meant the old in tank regulator don't worry lol I've got am adjustable regulator on the end of the fuel rail which dumps back into the tank into the jet pump thing like you were saying to scavenge fuel from the other side. The stock regulator, the top bit which presses into the pump assembly is welded up. I ran it last night quickly just to see what happened and it seems to work. Holds pressure after key off. Waiting on a sard regulator to come now so I can fit it as my permanent one. Running a super cheap spec one at the moment my friend had lying about
Do I need to put the vac line in? Or so I just set it at the standard 46psi and it's good to go? I've been told I need one to overcome manifold pressure but the altezza is tuned to overcome all that by controlling the duration in injectors or something isn't it?
