Default What is the stock fuel pressure for a 2000 XJR?
I'm going to add a fuel pressure switch as a safety so my NOS does not inject in the event of a fuel pump failure.

Can anyone tell me what the stock fuel pressure is?

About 2.8 bar over intake manifold pressure, as I recall.

So in American,

That is approx 40.6 psi.

So if I'm running 15 psi of boost, the stock fuel system can maintain 55 psi with the stock regulator?

Pressure in psig is correct at 40.6 As to the capability of the regulator or the pumps, I would have no clue!
