I'm pretty sure the regina FPR is 2.5 bar.

I know this is an ANCIENT post I'm replying to ... but I just wanted to update it for those who find this via a search engine.

Fuel pressure is roughly 45 PSI for both Bosch and Regina. Actual spec is 43.5 PSI for Bosch and 43-45 PSI for Regina if I remember correctly. Essentially the same for both.
