How should fuel pressure be relieved and what precautions should be taken when servicing fuel hose or fittings on Mazda 3?

Before servicing any fuel lines or fittings, relieve the fuel pressure and either remove or disconnect the cable from the negative battery terminal. In a vehicle, the fuel supply line connects the fuel pump located in the fuel tank to the fuel rail on the engine. Similarly, the Evaporative Emission (EVAP) system lines connect the fuel tank to the EVAP canister and the canister to the intake manifold. When working underneath the vehicle, check all fuel and evaporative emission lines for leaks, kinks, dents, and other damage. If you find any, replace them immediately. When disassembling the unit, if you see dirt in the lines, disconnect all lines and blow them out with compressed air; also, check for damage and deterioration of the fuel strainer on the fuel pump pick-up unit. It is important to replace fuel lines with lines of equivalent type and specification. Some steel fuel lines have threaded fittings, and a mechanic holding the stationary fitting with a wrench may turn the tube nut. Only original replacement tubing should be used for any plastic tubing you replace in the fuel system. Be sure not to bend or twist the tubing too tightly as it is not heat resistant and it must not be exposed to any excess heat. When replacing any flexible hoses, use original equipment only. And do not route fuel hoses or metal lines within four inches of the exhaust system or within ten inches of the catalytic converter. Make certain that no rubber hoses are firmly fixed against the truck where vibrations might chafe the hose, causing it to leak. Wherever possible, maintain a clearance of at least 1/4-inch around rubber hoses or metal lines and ensure they do not touch the truck's underbody.

Mazda 3 Fuel Hose Parts and Q&A

Filler Hose

Q:
How should fuel pressure be relieved and what precautions should be taken when servicing fuel hose or fittings on Mazda 3?
A:
Before servicing any fuel lines or fittings, relieve the fuel pressure and either remove or disconnect the cable from the negative battery terminal. In a vehicle, the fuel supply line connects the Fuel Pump located in the Fuel Tank to the Fuel Rail on the engine. Similarly, the Evaporative Emission (EVAP) system lines connect the fuel tank to the EVAP canister and the canister to the intake manifold. When working underneath the vehicle, check all fuel and evaporative emission lines for leaks, kinks, dents, and other damage. If you find any, replace them immediately. When disassembling the unit, if you see dirt in the lines, disconnect all lines and blow them out with compressed air; also, check for damage and deterioration of the fuel strainer on the fuel pump pick-up unit. It is important to replace fuel lines with lines of equivalent type and specification. Some steel fuel lines have threaded fittings, and a mechanic holding the stationary fitting with a wrench may turn the tube nut. Only original replacement tubing should be used for any plastic tubing you replace in the fuel system. Be sure not to bend or twist the tubing too tightly as it is not heat resistant and it must not be exposed to any excess heat. When replacing any flexible hoses, use original equipment only. And do not route fuel hoses or metal lines within four inches of the exhaust system or within ten inches of the catalytic converter. Make certain that no rubber hoses are firmly fixed against the truck where vibrations might chafe the hose, causing it to leak. Wherever possible, maintain a clearance of at least 1/4-inch around rubber hoses or metal lines and ensure they do not touch the truck's underbody.
