I was curious if any one knows what all four breathers are for on the back of my 07 800 I'm throwing it into a Frankenstein and need to know how to hook up the fuel pump and such

The very middle one that's 90 degrees goes to the top portion of the oil tank. The straight one closest to the middle runs the fuel pump. The other two are for the rave valve pressure and vacuum feeds to the solenoids.

OK so that's the one they were using for the fuel pump impulse on the rev. I was thinking of an XP. It really doesn't matter, they're all crankcase pulse fittings.

You would have to do an "oil pump delete". Search on here or Google.
