Fuel Lines & Breather Hoses
By OE Match
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
Fuel Line – Mixture Control to Warm-Up Regulator
High-quality replacement fuel line designed for Porsche 911 1974 models equipped with Bosch CIS (K-Jetronic) fuel injection systems.
This line connects the mixture control unit (fuel
distributor) to the warm-up regulator (WUR), playing a critical role
in regulating control pressure within the fuel system. This pressure directly
influences fuel mixture during cold starts and warm-up phases, making this line
essential for proper engine behaviour and drivability.

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.
