What was found
DURING ANNUAL INSPECTION, FUEL LINE WAS FOUND CHAFED NEARLY THROUGH AT HALF-WAY POINT. CHAFING CAUSED BY CARBURETOR HEAT CONTROL CABLE WHICH PASSES CLOSE TO THIS LINE WHERE IT GOES THROUGH THE FIREWALL. AREA IS VERY DIFFICULT TO INSPECT REQUIRING A MIRROR AND FLASHLIGHT. CHAFING HAD BEEN OCCURRING FOR SOME TIME. FUEL LINE WAS REMOVED, REPLACED, AND ANTI-CHAFE MATERIAL APPLIED TO CARBURETOR HEAT CONTROL CABLE.
