[DMCForum] Re: Rich A's continuing potential CPR problem

["cruznmd" <racuti1@xxxxxxxxxxxx>]

All that's in the CPR is a bi-metal piece attached to a spring. Like
the thermostat in your house for your HVAC.

That thing will curl up whether it's heated by the little element in
the housing, or by the heat from the engine. You yourself said the PRV
runs hot and you burn yourself hours after it cools down.

Even so it'll just be better to trouble shoot with a fuel pressure
test rig.

BUT, before we get to that, read my next post....
