IO-540 oil drain
 
I have a BPE IO-540 with the AFP fuel injection system. The oil drain has a Tee that connects a hose from a little higher point on the back of the engine. The bottom of the Tee has a B nut that must be removed to drain the oil. Why is the Tee necessary and is there a better way to drain the oil?

Something is not right. The oil drain should be on the bottom left side of the sump not on the back of the engine. I've got the same engine and FI from BPE and no tee. Got a pic?

Call BPE and ask Allen.

Do you have the cold air induction?
 
there is no internal oil pickup in that sump. You need to run a 10D line from the Tee to the upper fitting. The 10D hose has a bend radius of about 5 1/2" so the hose ends up being longer than you would expect...

Yup, that's what Allen said. It seems that when you use a horizontal injection system there is no pick up for the oil so they install a Tee fitting then a B nut for the oil drain.

It's a bit of a problem holding the Tee while breaking the B nut loose. I was told that someone makes a quick drain fitting that will work with the Tee?

BTW, a shout out to Barret: They saw my post and figured I'd be calling. Good to know they follow VAF!

I didn't see anything on the Saf Air website. Everything they show has male threads.

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?

I still haven't found a quick drain
 
Hot oil isn't the problem that I have, it's that the whole Tee turns when trying to get the B nut loose. Of course I use a back-up wrench on the tee, but it's impossible to hold it perfectly still.
