8mm Clear Yellow Tygon Hose F-4040A

8 mm is the outboard and generator fuel feed size, and TYGON5/16 is the busiest code in the F-4040A range for that reason. Maximum pressure at this bore is 25 psi, so it belongs on a gravity or primer-bulb feed rather than downstream of a pump. The tubing runs from 0 to 74°C and handles fuels, lubricants and some chemicals; the clear yellow wall lets you watch the line prime and spot water or debris before it reaches the carburettor.

Is 8 mm the same as 5/16?

It is the same item. The bore is listed as 8 mm and the stock code TYGON5/16 carries the imperial designation the tubing has always been sold under. Order by the millimetre bore and you will get the right one.
