Hi Fred / Chris,

Been watching this discussion with interest=C5=A0..

For the Legacy sy= stem (and may this could work for the other types):-
-How about a separat= e adjustable pressure relief valve
-Installed between the HP side and the return line
-Say a= djustable range 1000-1500psi or thereabouts

Finding a reliable/light w= eight valve may be tricky, but would something
like this help?


Regards,

John
