Here is a note from the Aeromotive
web site.
. . . .This minute
leakage, which is typical of all adjustable fuel pressure regulators, does not,
in any
way, affect the performance of the regulator.
Maybe it is typical of all Aeromotive pressure regulators; but my TWM adjustable
regulator is T’d off the line to controller B, and has worked fine for
four years with no leakage.
