To echo the above, I just installed the Mason lines in my 3.2 and am very satisfied. I did it with engine in the car and without removing the intakes. I did remove the air box and afm, which made life easier. It’s a little tricky to get to the fuel pressure regulator on the back left of the engine compartment, but certainly doable.

Also, Mason has a replacement line that goes from the FPR to the hard return line and you need to remove the crimped fitting from that line before installing the new hose. It’s in an awkward spot and you need to be careful not to damage the hard line. This is addressed in Mason’s instructions. I think he suggests using a dremel, but I found that a mini belt sander worked best. You just need to go very slowly.
