anyone know for certain what goes where? weber alpha regulator
cant find the info on the web, and have misplaced the bit of paper....
99% certain that the top connection is left open

thats backwards to what i have been told by someone else......
a is manifold/ open
but other sources tell me that b is from the fuel rail, and c is return to tank...
someone else must be using one?

Not the same regulator as yours - but I should think they all work in the same way ??
see here -- (the bottom outlet is the return on this example)

Looking at that diagram, it looks like it could work either way.

To me that diagram suggests if you got it the wrong way round you'd get a massive spike in pressure on start-up due to the smaller area of
diaphragm visible to that port. I doubt that your fuel pump could overcome the force exerted by the control spring without 'seeing' the
whole diaphragm. If it did actually open then it might continue to regulate as normal, but I think it would still struggle to hold itself open in
reality.

in at the side, out at the bottom on all of the regs I've fitted. I've made this mistake before. If you put it in the bottom the pressure
doesn't open the reg and you just stall the pump and blow hoses off.

I have the same regulator and
A. Manifold Vacuum or open to air
B. From fuel rail
C. Return to swirl pot (or tank return depending on how you are doing it)
