I had a lot of trouble with my SU's overflowing from the vents.  Several things 
contributed to the problem.

First was fuel pressure.  The replacement pump I had provided too much fuel 
pressure.  An inline regulator greatly helped this problem.

Second was my float bushings.  Until I got a correct oem SU set, I had quite a 
bit of vibration of the bowl.  It wasn't apparent until I replaced the bushings 
with the correct ones.  The difference was night and day.

Third was heat from the manifold.  This one still isn't as licked as I'd like 
it to be, as sitting in heavy traffic on a hot day still can get my fuel bowls 
percolating.  At the least, they fume strongly under these conditions.  Driving 
along things are fine.
