Purchased a small engine
oil cooler (300 x 150) and
oil pump take off with AN10 lines from VPW.
I wasnt happy with the take off pattern on their engine fitting so I grabbed the one as per the pic included that enabled better pipe routing.
There is a statement in the item description advising that the fitting must be installed with 'inline restriction'.
Not clear why you'd have AN10 fittings and lines too and and from the cooler then add inline restriction or how this would be installed. (AN10 - AN6 adaptors to form a choke point..?)
Look forward to some advice before creating any expensive engine issues..
