Need to order some fuel lines for a couple of small engines I have. What is the inside diameter of the fuel line from the fuel pump to the carb?

Go to shop.evinrude.com and look up the part numbers for your different motors.

Cut a short length off and take it to a small engine repair place. They'll sell it by the foot for not much.

The actual BRP size is 5/32", however that is hard to find. I use 3/16" on all my motors. Much more common.

+1 on the fuel line size. Ethanol resistant marine lines are best if you can find them and the budget allows. However, standard lines will work and should still last several years. Here's a handy link or two.

I found some clear fuel lines for motorcycles it comes in various sizes. less bulky and clear like common tubing
but fuel resistant.

local bike shops (honda - kawa...) should have some.
