AP fuel line size

1981 KZ650-H1 CSR.  Would 3/16" i.d. fuel line be appropriate for the accelerator pump fuel lines between the carburetor bowls?
Stock size in the diagrams is 3.5mm i.d. (3/16 converts to 4.76mm. not sure if the extra volume of fuel would matter to the diaphragm).

I think the problem would be leakage from the larger hose not sealing properly.

No eBay APP ID and/or Cert ID defined in Kunena configurationI have never purchased from these folks, but they seem to have a lot of positive reviews.



Oops, try this.

Thanks. the AP nipples are 4.1mm od at the shaft and the barbs are 5.5mm, so the 3/16 fits snug on the barb. with moose clamps was thinking it'll be fine. since the tubing is short and fixed in place between the carburetors.

A frickin' Porsche candy store for KZ fuel line???!!?

Motion Pro

Motion Pro lists some clear 1/8" X 3' fuel line (which is a bit smaller than 3.5mm) for $15.99. Considerably more expensive than the line I linked to above.
