Thanks for the reply Dan.
Connecting to the 'B' location was my first instinct, too. That's the output going to the oil cooler currently. With this being an outlet port which is at oil pressure level from the pump,
I was unsure if it's suitable to back-feed into it in order to pressurize the engine. I'm thinking this port must be downstream from the oil pump and feeds the engine, so back-feeding it (with the engine off) would in fact feed the engine, as well as the oil cooler if I tee into it it.
However, there may be pressure loss if oil flows backwards thru the engine's oil pump since there's no check valve that I am aware of and there may be pressure loss thru the oil cooler, too.
