I would say it's the non-brass one because the pulse from the crankcase has to push on the diaphram which is in the center, and seeing as thats' the only one going to the center....

I'm assuming you have dual carbs and the 90* fitting is from fuel tank and the other two go to the carbs?

but it says on the non brass piece and the brass piece and the 90* one is a arrow pointing out and the other 1 is pointing in so the 1 that is pointing in would be the fuel tank i am thinking look closly and you might be able to see the arows i was just checking if the o brass peice is the vacume hose?

but the one far away from you at the lower end and the 90* one has arows pointing out and the straight 1 pointing in for the arrow this isnt making much sense because would the ones with thebrass piece and arrows pointing out go to the carbs and the 1 pointin in from the gass tank ?

the fitting for the pulse line HAS to go to the middle, and the only one in the middle is the non brass one, opposites carbs, 90* tank.

I totally agree with 73elan because your crankase pulse hose has to be on the opposite side of the diaphram because you do not want fuel in your crankase.
If you look at the pump all the brass fittings are on the lower end of the pump and the other fitting is on the upper end (opposite side of the diaphram)
Brass fittings are always associated with fuel because this metal does not produce a spark when struck.
