IO-540 oil drain
I've just discovered I have the same oil drain problem on my BPE narrow deck engine. Allen confirmed the Saf-Air Products P5000 oil drain valve won't fit the Tee. I don't fancy the idea of going back to wrestling a B nut off a hot Tee fitting and covering my hands in hot oil.
Has anyone found a better solution that keeps a Tee for the for the hose to provide the oil pickup but takes a different quick drain valve? Is there a quick drain fitting to simply swap out the B nut?
