Carb fuel hose size

Before I go running around town looking for this part, can someone tell me if I'm reading these specs right?

Diagram:
http://www.bikebandit.com/assets/sch...SU0271_014.gif

Part #4 in the diagram is listed as:
4 13684-19F20 HOSE, 5.3X10.5(

Is that ID 5.3mm x Wall thickness 10.5 or IDxOD? I can't pull the hose and bring it to a shop for matching because I need the bike to get around, so I'd like to get the specs sorted before I make some phone calls.

Also are there any standard (non-metric) sizes I can substitute, preferably a little smaller so it doesn't leak? 1/4" seems to big and 1/8" way too small for 5.3mm ID.

Re: Carb fuel hose size

Why not buy a few sizes you think would fit, then keep around the stuff that doesn't? Isn't fuel-rated hose, like, $0.80/ft, or something? McMaster-Carr... what you don't use, you can keep for other tasks. Find the funds in the couch cushions.

Re: Carb fuel hose size

If you're replacing the short 90 degree hoses that supply fuel to the carbs I think you're going to want to go with the pre-formed hoses from Suzuki. A piece of universal fuel line from the local auto parts store is going to kink if you bend it that tight and starve that carb for fuel. Not to mention the challenge of finding the right ID to prevent leaks while still making installation possible.

You are not going to want a smaller ID than stock. I really struggled to get those off my 99 last month. Those hoses are thick and they are a tight fit. After the fight I had with them the clamps seem redundant.

As a side note, I tried to buy some replacement vacuum line at the local motorcycle shop and found that the ID I needed fell in between the standard sizes (motion pro brand I believe) they had on hand.

Re: Carb fuel hose size

+1 to PartsMan. I replaced all those hoses with store bought lines. The only one that had problems with kinks is #4. #1 is a bit longer and was/is fine as far I can tell. I used auto fuel injector lines.

Re: Carb fuel hose size

@Partsman: if you have trouble getting hoses *on*, try a bit of silicone spray. It doesn't hang around very long, so no worries about it slipping off, esp with clamps. But for those few seconds, it's a must-have.

Re: Carb fuel hose size

Doh! I was afraid I'd have to go OEM. Thanks for saving me the pain of finding out about kinking the hard way.

The prices I've seen for metric fuel hose is outrageous, like $5-10 per foot, which is why I don't really want to buy a bunch of different sizes (I'm blowing this month's bike budget on tires).

so if im reading this right then the oem fuel hose is 5.3mm i plan on getting a couple of elbows to solve the kinking problem
