Start the engine and check whether air is being sucked in from the engine oil level gauge, oil filler cap, or PCV hose etc. Standard: There is no air being sucked in. Check if there is air being sucked in from the intake system parts and connections between the air cleaner and the regulator. Standard: There is no air being sucked in.
Check if there is air being sucked in from the intake system parts and connections among the air cleaner hose, the resonator, and the regulator. Standard: There is no air being sucked in. Inspection 2: Inspect for exhaust gas leakage. Start the engine and check if there is any exhaust gas leakage from the exhaust system parts and connections between the cylinder head and the catalytic muffler. Standard: There is no exhaust gas leakage. Inspection 3: Inspect for fuel leakage. Start the engine and check if there is any fuel leakage from the fuel system parts and connections between the fuel tank and the regulator. Standard: There is no fuel leakage.
Check if there is fuel leakage from the fuel system parts and connections between the regulator and the LPG adapter. Standard: There is no fuel leakage. Check if there is fuel leakage from the fuel system parts and connections between the regulator and the injector. Standard: There is no fuel leakage. Inspection 4: Inspect the regulator primary pressure. For the regulator primary pressure inspection, refer to the LPG repair manual. Section 19
