VS fuel pressure

[aceventura]

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?

lol i would say 240kpa is approximately 235-245kpa

did u test your fuel pressure and its reading 240kpa?

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???

wouldnt know who publishers what as long as its published and i can reference it im happy. it is strange, wonder if anyone has an elleries that they can post up specs from?

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
