tw200 petcock barb fitting too small for 5/16 or metric hoses

So I didn't anticipate the oem yamaha tw200 petcock would have a smaller barb fitting (1/4" equivalent in english)

Did you guys do something to step up or adapt from the 1/4" when going to your t fitting and later 5/16 or the metric hoses to carbs? Or did you replace the barb that is pressed into the tw200?

I briefly wondered about drilling the tw200 to use the 1 barb fitting from the original petcock but don't have metric bits and didn't want to ruin the new part.

I am sure there is a simple solution I am missing here and will feel dumb about

2002 vn750
AGM battery, Shinko 230 tires oversized front
Ear shaved - k&n pods, drilled clutch basket
MCCT
40/138 jetting

If I can split a case and make it work - you can too!

Your 5/16" fuel line is incorrect size.

You may have it clamped on the carb's w/o leaking........ but ? ? ?

1/4" is proper for Fuel Line.

I utilize ClearFuel Line and 3/16 “ Vacuum Line - - w/o clamps (stretches for tight connection)...
hope this helps....

Ok, didn't realize 1/4 couldfit the carbs. Knifemaker was clear 5/16" is the size to use and the oem metric hose is clearly bigger than 5/16.

Wouldn't you know I had all the rights parts to switch over prior and returned them all..

I'm a little too ocd to not put clamps on even tight fittings ha
