Build your own adjustable fuel pressure regulator ;)

after a quick search I found this how-to and wondered if one would cut the 4A-GE regulator just flush between the flatish surface and vacuum nipple (without cutting too deep to not harm the spring), if this would make the need for the modification redundant - not sure if there is a 1.5-2mm gain to be had from that but maybe worth a shot. Only concern I'd have that way is if the top surface where the B&M is resting on collapses/folds...

The problem is the FPR would be too wide @ the seam. I cut through the edge of the top, and remove it. It is only after the top is removed that its outer diameter matches the inner diameter of the B&M case
