John,
I think the easiest thing to do would be= to incrementally shorten the spring in the thermal relief valve and then c= heck the cracking pressure.
No extra parts required.  While we = haven't had any cylinders blow up (that I know of), this might be worthwhil= e investigating.  I see 1,800-1,900 psi on a regular basis.  I wo= rry a bit when the reading goes off-scale.

<= BR>Hi Fred / Chris,

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

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

Finding a reliable/lig= ht weight valve may be tricky, but would something
like this help?
