Hi Robert, the relief is a modified Norgren minature PRV, which I just happened to have, grafted onto the tank connection. It's a very simple design so I'm sure it could be copied if you've got access to a lathe. Fitted the pump and all the pipework onto the car this afternoon but need to tweek some of the springs and cure a few leaking joints but all looking good so far.
