Vacuum vs Fuel pressure

[Salan95VS]

Hi everyone
I’m chasing the readings for what a standard series 1 VS 5ltr would have in terms of vaccum vs fuel pressure, if anyone has measured this before or has knowledge on it to share would be greatly appreciated.
Cheers

just find out max pressure (key on engine not running) then minus manifold vacuum at 1:1 ratio

Should be 43.5 psi/3 bar with the manifold reference disconnect. With manifold reference connected it will read a few psi less.
