I only used this thing once, nothing wrong with it at all I just don't need it. I don't remember the part number right now, but it's adjustable btwn 4.5 and 10 psi. I also have two AN fittings that go from 3/8 NPT (fuel pump outlets) to -6.
I also have the mounting bracket for the regulator.
$40 for everything. PM me if you're interested.
