That's a sound and positive fix.

- - However it requires changing the dump valve, running a return = line and=20 pump modification (replace the reservoir).

- - - - Later models of the OilDyne pump have a port between = the two=20 pressure ports that dumps directly to the reservoir.

- - - - - - no reservoir changing needed.

- - and the pilot has to recognize the problem and intervene.

Obviously, I prefer a fix that does not = require pilot=20 intervention - - fully automatic.
