1979 CV34 crabs

[Leslie]

My bike has an after market petcock on, i have bought a NOS from the US. can anyone tell me if the spigot at the bottom goes to fuel the CV34s and the one on the back of the tap with the black cap i would imagine it attaches to the CV34s vacuum am I correct.

Yes, small one on the back is vacuum, and your carbs are BS38s, not 34s.

I hope that downward facing fuel outlet on your new petcock allows enough clearance for the fuel line. Stock petcocks faced the fuel outlet either in .....

..... or back .....
