What This Product Does:
- Transfers vacuum to control the air injection valve or related components
- Supports proper operation of the secondary air injection system
- Helps reduce exhaust emissions during cold starts
- Assists in improving engine efficiency and emissions compliance
- Ensures accurate system response through proper vacuum delivery
Symptoms Of Wear Or Failure:
- Check engine light (emissions or secondary air injection fault codes)
- Rough idle or unstable engine RPM
- Hissing or whistling sound from the engine bay (vacuum leak)
- Reduced engine performance
- Poor fuel economy
- Failed emissions test
- Secondary air injection system not activating properly
- Cracked, brittle, or collapsed hose material
- Loose or disconnected vacuum line
Why Replacement Matters:
- Replacing a worn air injection vacuum line is important because it ensures proper vacuum delivery to the secondary air injection system. Over time, heat and engine bay exposure can cause the line to crack, harden, or leak.
- If a vacuum leak develops, the air injection system may not function correctly, leading to check engine lights, reduced emissions performance, rough idle, and potential failure of emissions testing.
- Installing a new vacuum line restores proper system control, prevents vacuum leaks, maintains engine efficiency, and ensures the vehicle meets emissions standards.

Inlet Manifold Breather Line for Fuel Tank
Restore the efficiency of your Porsche's evaporative
emissions system with this OE Match Inlet Manifold Fuel Tank Breather Line.Manufactured to original equipment
specifications, this high-quality replacement breather line ensures the safe
transfer of fuel vapours from the fuel tank's EVAP system to the inlet
manifold, where they are burned during normal engine operation.
Fits:
- Porsche 958 Cayenne Turbo V8 4.8L Petrol (500Hp) 2010-17

The inlet manifold breather line is a vital component of the Porsche fuel vapour recovery system. It prevents harmful fuel vapours from escaping into the atmosphere while maintaining correct engine vacuum and emissions performance. A leaking or damaged breather line can cause vacuum leaks, engine management warning lights, rough running and fuel vapour odours.
Constructed from premium fuel-resistant and heat-resistant materials, this OE Match replacement delivers factory-quality fitment, dependable sealing and long-term durability, making it an ideal solution for routine maintenance or emissions system repairs.
What Does the Inlet Manifold Fuel Tank Breather Line Do?
The breather line connects the fuel tank evaporative emissions (EVAP) system to the inlet manifold, allowing fuel vapours collected within the charcoal canister to be safely drawn into the engine and burned during combustion.
Its functions include:
- Transporting fuel vapours from the EVAP system to the engine.
- Preventing fuel vapour emissions from escaping into the atmosphere.
- Maintaining correct intake vacuum.
- Supporting efficient engine performance.
- Helping reduce exhaust emissions.
- Assisting compliance with modern emissions regulations.
A properly functioning breather line is essential for maintaining both engine efficiency and environmental performance.
Why Does the Breather Line Fail?
The breather line is constantly exposed to engine heat, vacuum pressure and fuel vapours, which can eventually cause deterioration.
Common causes of failure include:
- Heat-related ageing.
- Hardening or cracking of the hose.
- Fuel vapour degradation.
- Vacuum leaks.
- Damaged hose connectors.
- Engine movement stressing the pipework.
- Wear during servicing or engine repairs.
Replacing worn breather lines helps maintain the integrity of the EVAP system and prevents unwanted air entering the intake system.
Symptoms of a Failing Breather Line
Typical warning signs include:
- Engine management warning light.
- EVAP system fault codes.
- Fuel smell around the engine or vehicle.
- Rough or unstable idle.
- Vacuum leak or hissing noises.
- Poor fuel economy.
- Reduced engine performance.
- Visible cracking or deterioration of the hose.
Replacing the breather line promptly can often eliminate emissions-related faults and restore smooth engine operation.
When Should the Breather Line Be Replaced?
Replacement is recommended when:
- The hose becomes brittle or cracked.
- Vacuum leaks are detected.
- Fuel vapour leaks are present.
- EVAP fault codes are diagnosed.
- The inlet manifold is removed during servicing.
- Carrying out preventative maintenance on higher mileage vehicles.
Replacing ageing breather hoses helps maintain reliable emissions system performance and prevents future vacuum leaks.

What This Product Does:
- Carries vacuum pressure from the intake system to connected components
- Supports proper operation of emissions and engine control systems
- Assists in regulating airflow and system actuation
- Helps maintain smooth engine performance and efficiency
- Prevents vacuum leaks that can affect drivability
Symptoms Of Wear Or Failure:
- Check engine light (vacuum leak-related fault codes)
- Rough idle or unstable engine RPM
- Hesitation or loss of power during acceleration
- Poor fuel economy
- Engine misfires
- Whistling or hissing sound from the engine bay
- Hard starting or extended cranking
- Vacuum-controlled components not working properly
- Cracked, brittle, or collapsed hose material
- Loose or leaking hose connections
Why Replacement Matters:
- Replacing a worn vacuum hose is important because it ensures proper vacuum pressure is delivered to critical engine systems. Over time, heat and engine bay conditions can cause the hose to crack, harden, or leak.
- If a vacuum leak develops, it can lead to rough idle, poor fuel economy, reduced engine performance, and trigger check engine lights. In some cases, vacuum-controlled components may stop functioning correctly.
- Installing a new vacuum hose helps restore proper engine operation, maintain efficiency, prevent drivability issues, and support long-term system reliability.
