Re: Fuel line

3/8" line would be the best. That allows for better fuel flow and less problems at high speed.

Re: Fuel line

Would the diameter not be dependant on the couplings on tank/motor? I would imagine that despite a thicker pipe, the fuel would have to flow through these coupling openings at a rate based on the coupling's diameters?<br /><br />Have I got it wrong? I suspect that using a pipe with a smaller diameter than the couplings, would be a problem.
