I have this question buried in another thread that didn't get answered:

The Gregory's manual quotes the fuel pressure for a VS as:

Approx 280 kPa at idle
320-350 kPa at idle with vacuum hose disconnected.

My question is what does Approx 280 kPa" mean? Is 240 kPa approximately 280 kPa?

I had the mechanic test the pressure - I don't have the gear.

Results were 240 kPa at idle with a flow rate of 2L/min. He said the pressure and flow was within specifications, and I was wondering whether he was confusing it with the VR fuel pressure. It seems low to me, but the mechanic might just be realistic - Not sure.

just checked my book, haynes, and it lists the pressure at

idle = 240-260kpa
engine off = 280-320kpa

seams in range to me :)

Thanks Ephect - although I find it strange that the Haynes and Gregory's manuals list different amounts, seeing as the Gregory's manuals are published by Haynes???

One thing I did notice is that both the Ellery and Haynes manuals are for VR-VS or for VN-VS respectively. Only the Gregory's manual is VS specific.

Might have something to do with it???

EDIT: Bosch also recommend different regulators for the VR and VS
