Motorcycle Repair: fuel line hook up, suzuki gs 500, vacuum line

Question
have a  90 suzuki gs 500 and they hooked fuel lines up worng wounndering if u might be able to help

Answer

Fuel GS500 How did 'they' hook the fuel lines up wrong?  I think on the GS500 there is a vacuum activator and a fuel line.  The fuel line goes from the petcock to the feed pipe on the carburettors.  The vacuum line normally goes to a small line in front of the carburettors.  Do you have a manual for the bike?  Good luck,  Jan
