1/4 NPT sounds right Stewart for the outlets.
It should be the same size as the brass inlet fitting on the carbies.

3/4 inlet is HUGE :shock:

I just run a 1/4 fuel line to all of mine, tee'd into the first carb,
tee'd into the second, elbow into the last.

You could fit a 3/4 to 1/4 reducing bush into the inlet side of your fuel block,
Then run a 1/4 hose/pipe from the fuel pump to the fuel block.

You wont need a fuel line any bigger than that :wink:
