The EVAP system is made up of six essential components, including the charcoal canister, the fuel tank, and the EVAP system lines and hoses. These hoses connect the various parts of the EVAP system, allowing fuel vapours to travel from the fuel tank to the charcoal canister and eventually into the engine. Old hoses are prone to cracking and dry rot and should be replaced, as they are a potential source of liquid and vapour leakage.

What You'll Learn
Fuel-compatible materials are required for hoses
Fuel line hoses are typically made of rubber, metal, braided nylon, braided steel, PTFE-lined, or plastic. Metal is the most durable material, but it is also the most expensive. Rubber hoses are flexible and can be cut to length, but they will wear out over time and rub if not properly secured. PTFE-lined hoses are also an option, as they are resistant to fuel fumes.
In older models, fuel line hoses were made of copper, which is easy to install and service but bulky and expensive. Modern vehicles often use plastic, usually nylon, for fuel lines.

Hoses connect the fuel tank to the charcoal canister
The EVAP system lines and hoses connect the various parts of the EVAP system, allowing fuel vapours to travel from the fuel tank to the charcoal canister and eventually into the engine.
Old hoses are prone to cracking and dry rot and should be replaced, as they are a potential source of liquid and vapour leakage. Replacement hoses should be rated for fuel or fuel vapour; coolant hoses will not hold up to long-term fuel exposure.

Hoses are prone to cracking and dry rot
When replacing hoses, it is important to use a fuel-compatible material. Some sources recommend using a combination of fuel and tranny rubber tubing. However, it is worth noting that the overall diameter might be more than stock. For this reason, it is important to check the fitment of the new hose before installation.
One user replaced six EVAP lines in their RX300 with a combination of fuel and tranny rubber tubing. They used SAE30R6 tubing, which is specifically designed for fuel and emissions. This user also cut off the ends of the bad hose and stretched what was left into place as a temporary solution.
The EVAP system is made up of six essential components, including the charcoal canister, purge valve, vent solenoid, gas cap, fuel tank pressure sensor, and EVAP system lines and hoses. These lines and hoses connect the various parts of the EVAP system, allowing fuel vapours to travel from the fuel tank to the charcoal canister and eventually into the engine.

Hoses should be rated for fuel or fuel vapour
The EVAP system is made up of six essential components: a charcoal canister, a purge valve, an EVAP vent solenoid, a gas cap, a fuel tank pressure sensor, and EVAP system lines and hoses. The EVAP system lines and hoses connect the various parts of the EVAP system, allowing fuel vapours to travel from the fuel tank to the charcoal canister and eventually into the engine.
Old hoses are prone to cracking and dry rot and should be replaced as they are a potential source of liquid and vapour leakage. Coolant hoses will not hold up to long-term fuel exposure. Hoses with a nitrile rubber inner liner reinforced with single-ply braided cord and a neoprene rubber cover, such as SAE 30R6 and 30R7, are designed for fuel systems rated at 50 PSI or less of working pressure.
It is important to regularly inspect fuel vapour hoses for signs of wear and tear or damage due to age or extreme temperatures. If any damage is found, it should be replaced immediately.

Hoses can be replaced with fuel and tranny rubber tubing
Old hoses are prone to cracking and dry rot and should be replaced, as they are a potential source of liquid and vapour leakage. Replacement hoses should be rated for fuel or fuel vapour; coolant hoses will not hold up to long-term fuel exposure.
When replacing hoses, it is better to use fuel or emissions hose. The overall diameter might be more than stock. SAE30R6 should be suitable.
One user replaced six EVAP lines in their RX300 with a combination of fuel and tranny rubber tubing. They also mentioned that they were going to buy some 5/16" fuel hose.

Frequently asked questions
You should use a hose that is rated for fuel or fuel vapour. Coolant hoses will not hold up to long-term fuel exposure.
There are six essential components that make up the EVAP system: Charcoal Canister Purge Valve, EVAP Vent Solenoid, Gas Cap, Fuel Tank Pressure Sensor, EVAP System Lines and Hoses.
If the pressure sensor detects a significant change in pressure, it may indicate a leak or malfunction in the EVAP system.
