Fuel Injector Leakage Test

Install Fuel Injector Tester/Cleaner (113-00001). Clean injectors according to tester/cleaner manufacturer's instructions. After injectors are cleaned, check for fuel system pressure loss. If pressure loss is observed, remove injectors and individually check injector's leakage rate. Maximum injector leakage rate is one drop per minute. Replace injector if maximum leakage rate is exceeded.
