I use Turbonetics parts exclusively with impeccable results. Turbonetics also supplies the US military, and that fact was huge when deciding to use thier units in my Porsches.
The Deltagate Mark II is discontinued, but I kept notes on the spring colours, and corresponding PSI values:
3 PSI spring: green
5 PSI spring: blue
7 PSI spring: silver
9 PSI spring: black
Based upon your photo, you have a 7 psi unit. I hope that helps.
