Fairley clogging up the forum on this subject...? (-:
Item No 10 on the diag, would appear to be an oil pressure switch which logically detects oil pressure in the galleries, thus should be an ideal access point. However the whole idea of using a oil can with the ability to pump the oil, is that it can be used to create pressure in the system to the extent you feel it taking more physical effort to operate the pump action on the oil can, and with a bit of luck if you still have the oil pressure sender unit in place and electrically connected, with the ign on there is a chance that the gauge may (if operational) may just display some measure of the pressure that ideally you are introducing to the galleries via the oil can..?
From the diag it also seems that there may be a gauze filter adjacent the oil pressure release valve... Wonder if that may be playing a part... Hmm..?
I reiterate that I have never had any of this kit apart on my +8. I am using no more than logic (failed or otherwise) in this regard..
