Yes on top there is a allen screw, originally covered with a alloy/tin plug, this can be prised out and the screw turned to adjust pressure if needed, I use this on my own 2wd running greys.

Does it need adjusting from standard pressure? Am assuming you'd need a fuel pressure gauge if you started messing with the screw on top?
