What size are my fuel hoses?

[Joe Monaco]

I’ve got CAT 3126 420 HP motors. The CAT part fuel hose on the governor is 3/8 inch. Would CABO put the same size line for the fuel hoses to the engine or would they up it to 1/2 inch? I’m adding a fuel flow sensor and trying to figure out what size barb setup to order. The hoses have numbers on them but no sizing info. Thanks for any help.

Thanks Rob!

I was hoping those numbers would mean something to someone. Obviously I didn’t even notice the one that mattered. Great catch!

Hose Dash Size

Joe,

Your picture just caught what we needed, see the -8 at the tip of my arrow, that is the code for 1/2″ ID for a hose of this type.
