I just took the two hoses off the fuel valve on my KZ650 and thought both were fuel lines. So, I poured carb cleaner into both tubes. Now, I think "that was dumb." I think one was a vacum line. Have I got a problem and can I fix it?
Thanks for any real help.

 

Is the vacuum line dried out, or cracked? if not then it should be fine. If it is then vacuum line is like 25 cents a foot. Fuel hose is generally made from solvent resistant hose, so it should be OK. I would go cut some extra line from one of the vac lines on my Jeep, and use that.

 

Welcome philip to KF.
The vacuum line clear now?

 

If the engine is running well, then you don't have a problem.
