Fuel Lines & Breather Hoses
By OE Match
- Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
The Fuel Line for Warm Up Valve is a fuel line designed for classic air-cooled Porsche 911 models equipped with Bosch CIS / K-Jetronic mechanical fuel injection. This line connects to the warm-up valve / warm-up regulator and plays an essential role in maintaining correct fuel routing and pressure control during cold starts and engine warm-up.
Fits:
- Porsche 911 T-K 1972-1973 2.4L LWB (F)
- Porsche 911 1974-1976 2.7L / 1976 3.0 Carrera
Fits On To Diagram Ref No 28
In CIS fuel systems, the warm-up regulator helps manage control pressure so the engine can start cleanly when cold and transition smoothly to normal running conditions as temperatures rise. A properly functioning fuel line is critical to ensure stable pressure and leak-free operation. Over time, original fuel lines can degrade from age, heat exposure, and vibration, leading to cracking, seepage, or weakened fittings.
What This Product Does:
- Carries fuel to/from the warm-up valve / warm-up regulator
- Helps regulate control pressure in CIS injection systems
- Supports smooth cold start operation and warm running performance
- Ensures fuel is delivered through the correct metering path
- Maintains leak-free
Symptoms Of A Failing Fuel Line:
- Fuel smell in the engine bay
- Visible fuel seepage or dampness around fittings
- Cracked or aged line material (especially on older CIS cars)
- Hard starting or poor cold running (if pressure is affected)
- Rough idle during warm-up
- Potential fuel leaks creating a fire risk
Why Replacement Matters:
- Prevents dangerous fuel leaks in the engine bay
- Maintains correct CIS fuel pressure regulation for proper drivability
- Supports reliable cold starts and smoother warm-up operation
- Helps avoid engine running issues caused by pressure loss
- Preserves safety in classic Porsche maintenance

This metal fuel line provides reliable fuel-circuiting within the vehicle’s structure, directing fuel return or feed through the centre tunnel. It must maintain integrity under fuel pressure, vibration and heat, while resisting corrosion for long service life.
Over time, the original fuel lines in the centre tunnel can deteriorate due to vibration, fuel exposure, and age. This can lead to leaks, vapour loss, or safety risks. Replace the fuel line when:
• Corrosion or rust is visible on the metal surface.
• You notice fuel odour or damp spots near the tunnel area.
• The line shows signs of wear, cracking, or deformation.
• Performing a full restoration, engine rebuild, or fuel-system refresh.
Installing a high-quality new fuel line ensures proper routing, durable materials, and leak-free operation - restoring the safety and reliability of your Porsche’s fuel system.

Fuel Pressure Line – To Fuel Accumulator
High-quality replacement fuel pressure line designed for Porsche 911 T-K, 911, and 911S models equipped with Bosch CIS (K-Jetronic) fuel injection systems.
This line connects the fuel system to the fuel accumulator, a critical component responsible for stabilising fuel pressure and ensuring smooth engine operation—particularly during starting and transient load conditions.
Fits:
- Porsche 911 T-K 2.4L - 1972-73
- Porsche 911 2.7L - 1974
- Porsche 911 S 2.7L - 1974
Diagram ref no 18
As part of the high-pressure CIS fuel network, this
line plays a vital role in maintaining consistent fuel delivery across the
entire system.
Manufactured to OEM specifications, it provides precise fitment and durability, making it ideal for maintenance, repair, or full fuel system restoration.
Key Features
• Direct replacement fuel pressure line to accumulator
• Suitable for Porsche 911 T / 911 / 911S (CIS systems)
• Designed for high-pressure fuel delivery
• OEM-correct routing and fitment
• Resistant to fuel, heat, and pressure
• Ideal for single replacement or full system rebuild
Part of a Complete CIS Fuel System
This fuel pressure line operates within a fully integrated CIS fuel delivery system, including:
• Fuel pump
• Fuel accumulator
• Fuel metering head
• Injector lines (to each cylinder)
• Fuel return lines
• Fuel injectors
Each component is interconnected—meaning performance issues are often linked across multiple parts.
Why Replace Fuel Pressure Lines as a System
Due to age and operating conditions, CIS fuel lines often degrade together.
Common reasons to replace include:
• Pressure loss or inconsistent fuel delivery
• Hard starting or poor warm running
• Fuel leaks under pressure
• Age-related cracking or internal restriction
For best results, inspect or replace multiple lines together to restore full system performance.

OEMatch Fuel Lines & Breather Hoses — Fit, Function, Confidence
OEMatch Fuel Lines & Breather Hoses for Porsche models are selected to support application-specific needs. Fuel lines and breather hoses route petrol, manage vapour and equalise tank pressure across supply, return and evaporation systems. Correct materials and secure connections reduce the risk of leaks, fuel odour and refuelling faults while helping preserve steady engine running and emissions control.
- Fuel supply and return lines with factory-style fittings
- Vapour and breather hoses for tank and canister circuits
- Flexible tank-to-engine connectors and quick-connect adaptors
Understanding OEMatch Fuel Lines & Breather Hoses
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original fuel lines & breather hoses.
OE (Original Equipment) refers to parts matching original specifications for the fuel lines & breather hoses and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM fuel lines & breather hoses engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Fuel lines deliver pressurised fuel to injectors or carburettors and breather hoses equalise tank pressure and manage vapour routing; both are integral to safe refuelling, combustion stability and emissions control. OEMatch focuses on Porsche applications across gaskets to suspension hardware and engine parts, cataloguing thousands of part numbers and OE cross-references while continuing to develop new lines to support vehicle upkeep.
- Helps prevent fuel leaks and odour by restoring secure sealing
- Supports correct fuel delivery and consistent engine running
- Improves refuelling behaviour and reduces risk of vapour lock
- Ageing and heat exposure causing cracking, hardening or swelling
- Exposure to ethanol or contaminated fuels leading to internal damage
- External abrasion, chafing or damage from incorrect routing
- Loose or corroded fittings that allow leaks and pressure loss
The Importance of Replacing with OEMatch Fuel Lines & Breather Hoses
Replacing aged or damaged hoses reduces fire and fume hazards, avoids drivability and refuelling faults and helps maintain emissions systems. For Porsche models, renewed lines and vents contribute to reliable starting, stable idle and accurate fuel pressure, supporting safe operation and predictable engine response.
- Selected for Porsche applications and supplied with relevant fittings where specified
- Made to original-spec dimensions and tolerances to match factory routing and clearances
- Constructed from modern, fuel-resistant materials designed for heat and ethanol exposure
Support & Advice
Fitting can appear straightforward but may require procedures such as correct torque settings and careful routing of hoses. If you lack the correct tools or model-specific knowledge, we recommend professional installation. Recheck fasteners and connections after initial running and observe for any diagnostic codes or fuel odours.
