Gear type pump pressure relief valve
#7
Thanks chaps. Very useful.

About 10 years ago I made a remote PRV that mounts on the bulkhead. It uses A7 workings with a round ball in a simple aluminium block, with the bypass going straight back into an extended oil filler (mag engine). The original is blocked up solid so can't bypass.
It's worked perfectly for all these years but recently I've had odd fluctuations in pressure, suggesting something has worn or been damaged, hence the "back to basics" approach. 
I'll investigate the problem and come up with a solution.
