Fuel pressure

[equate975]

I need to check my fuel pressure but we all know its a complete bitch to get the fuel line off the fuel rail.

Would it matter if I disconnected the hose after the secondary pump and tested there?

Also what should the pressure be?

Thanks

3.0 bar I would say.

3.5 bar is stock on the s50/s52. I think it is the same on m50/m52s although not pos. Equals roughly 51 psi.
