What fuel tube size to use?

[Derrick Stewart]

So which size of fuel line to use?

Is it just personal preference or is there a hard and fast rule depending on the motor size?

Derrick,

I (and many others too) use medium tubing for 21/45 engines. Use large tubing for the larger ones as they need the increased fuel volume.

When you say medium do you mean 3/32" as opposed to large 1/8" tubing

Is tis correct?

That would be correct.
