fuel line size. TRX 300 | Honda ATV Forum
28/8/2013· If it doesn''t fit tight, step down a size to 1/4". The right fuel line will seal without leaking, but clamp it anyways. Oem or hose type will work fine, whatever holds it on. EDIT: This applies to the 300 fourtrax. The 300ex sport quad gas tank has a wired angle and your better off to buy the preformed oem fuel line.
