Reply to "Head vent mod for trapped air"

Ahhh, My unfortunate Christmas tree arrangement. I never figured out how to arrange that plumbing with fewer pieces for a more elegant execution. However, it works well. I had called Aeroquip for a custom fitting providing sizes to tie it all together and the representative told me flat out that I couldn't afford it.

To your question. The braided line on the left feeds oil to the rear of the engine from the outlet adjacent the oil filter. This mod was once more popular however became more controversial. Our testing validated its efficacy. The line off to the right feeds the rear of the motor from the Accusump. The brass fitting in the left line is a one-way check valve forcing the accusump's discharge into the rear of the engine so it isn't wasted on the oil filter. The lower copper line, of small diameter, feeds a mechanical oil pressure gauge and the sender adjacent to it signals a low oil pressure light.
