I would suggest screw your HP in not out most HP regs out increases pressure.
LPR is in to increase opposite.
Leak there is most likely an o-ring is dry rotted or just needs lube.
Unscrew lpr till screw is loose so no pressure on reg springs(not out)
Screw HP in slow till it stops open 2 maybe 3 full turns see if lpr leaks. If it does o-ring is dry rotted or just needs lube.
if not slowly screw lpr in till it gun cocks with no problem.
What type gun do you have?
