Carb fuel tubes

Its the tubes between the to carbs have middle one and two for both pairs of carbs I was wonder what orings will work for them cause I sprung a little leak one 1980 kz750 h1 four

Did you mean the overflow tubes ?

From Kawasaki.com the o-rings are listed as Active. At Partzilla they are $1.79 each. ouch.
Kawasaki does not provide any measurements for them. Searching the part # at Z1Enterprises.com didn't yield any results, but they do carry a good selection of o-rings. A HF metric nitrile or viton o-ring kit may have the needed size --- it wouldn't have to be identical. Auto parts stores sell individual o-rings out of a similar kit.

ah

Got cha now

For future knowledge advance auto mm oring kit fit them perfect thanks again
