Where fuel lines go?

[bouner]

I have a 1987 Johnson 100 V4 with no VRO. Where do the 4 vacum lines that are on the intake manifold go to? The engine block also has 3 small fitings 2 on one side and one in the side of the starter. What are those for, i guess for oil from the prior VRO. What do I put there. Need help. Also, carbs leaking fuel and fuel line goes dry in a matter of minutes. I put a new fuel line, din't help. Engine runs well at high RPM but dies at idle. Also the bulb(also was change) never stays hard even if you pump it alot

bouner,<br /><br />If you look really close, there are four of those fittings on the block, two each side.<br /><br />They have nothing to do with VRO, something to do with crankcase pressure. They are attached to a one way check valve at each block connection..

Thanks Djohns for the input . Still can't find the fourth fitting. i'll keep looking. By the way the other 3 had no check valves, they had fuel lines that went to the primer and to the intake manifold fittings. Is that ok?
