Do you use a water overflow bottle Andy? If so will it work as a scavenge as well?
I will see if auo barn or bursons has the radiator cap.
My car is still not finished so it hasn't been driven on the road.
The VZ radiator cap will not fit a radiator that takes a HQ style radiator cap.
A 16 psi radiator cap should be close enough to do the job.

I am considering running Evan Waterless lifetime coolant which does not expand when it gets hot so there is no need for an overflow recovery system.

There is a similar product made in Australia by Liquid Intelligence.
