Leafield A3 pressure relief valve parts

I've have an Avon FRB380 with Leafield pressure relief valves on the tubes. I got the boat used from a local fire department. One of these relief valves has always leaked. The solution used by the FD, and continued by me, has been to stopper off the valve opening, which has worked fine.

Feeling the need to tinker, I finally took it apart, hoping the leak was caused by some debris that could be cleaned out, but found a hole in the rubber diaphragm (photo attached).

Is there a US based source for these parts? I'd like to get it back to normal working condition to protect against over-inflation.

The spring in the valve is painted red. I need to research to find out what this signifies, but I assume this indicates the blow off pressure.

With the valve removed I was able to get the cell phone in the tube and take a picture of the adjacent baffle. Thought it might be of interest to see what divides the tubes. The adjacent tube was at 0.3 psi.
