Manufactured to match the original equipment specifications, this oil level sender fits inside the engine's external oil tank and communicates the oil level to the dashboard-mounted oil level gauge.
The classic Porsche 911 uses a dry-sump lubrication system, in which engine oil is stored in a separate tank rather than solely in the engine sump. The oil level sender plays an important role in providing the driver with a visual indication of the quantity of oil present in this external reservoir.
The sender uses a float-operated mechanism to detect changes in the oil level. As the oil rises or falls, the float moves and changes the electrical resistance within the sender, allowing the dashboard gauge to display the corresponding oil level.
Over time, the original sender can deteriorate due to prolonged exposure to hot engine oil, temperature fluctuations, vibration and ageing electrical components. A worn or faulty sender may produce inaccurate, intermittent or completely unresponsive oil level readings.
Replacing a defective sender with an OE MATCH component helps restore reliable dashboard oil level indication, making it easier to monitor the lubrication system and maintain the correct engine oil quantity.
Ideal for classic Porsche servicing, oil tank refurbishment, dashboard instrument repairs and restoration projects, this oil level sender provides a practical original equipment-style replacement.

Porsche 911 1970-98
Manufactured to match the original equipment fitting arrangement, this cap provides a secure closure for the external engine oil tank's filler opening, helping protect the lubrication system from dirt, dust, moisture and other environmental contaminants.
Unlike conventional engines that store most of their lubricating oil in a sump beneath the crankshaft, the air-cooled Porsche 911 uses a dry-sump lubrication system with a separate oil reservoir.
This external oil tank stores the engine oil and forms an important part of the circulation system that supplies lubrication to the engine's moving components.
The oil tank filler cap allows access to the reservoir when topping up engine oil or carrying out routine servicing.
Its bayonet-style fastening mechanism is designed to engage with the corresponding oil tank filler neck, providing a secure and convenient closure.
The correct fitting and condition of the oil tank cap are important for maintaining a clean, properly enclosed oil reservoir.
Over time, an original oil tank cap may deteriorate due to repeated removal, exposure to heat, oil residue, vibration and natural ageing. The sealing surface may become damaged, while the locking tabs or bayonet mechanism may become worn or distorted.
A loose, damaged or incorrectly fitting oil tank cap may allow oil mist or residue to escape around the filler neck and permit contaminants to enter the tank.
Replacing a deteriorated cap with the OE MATCH Oil Tank Cap 91110707204/1 helps restore secure closure of the oil filler opening, maintain the cleanliness of the lubrication system and preserve the original Porsche oil tank arrangement.
Ideal for routine servicing, oil tank refurbishment, engine bay restoration and classic Porsche maintenance.

Understanding OEMatch Oil Tank & Parts
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original oil tank & parts.
OE (Original Equipment) refers to parts matching original specifications for the oil tank & parts and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM oil tank & parts engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
The oil tank acts as the reservoir in a dry-sump lubrication system, keeping oil separate from the crankcase to prevent aeration and to ensure steady pressure during heavy cornering, braking or acceleration. Supporting components such as caps, breathers, hoses and fittings route oil correctly, maintain seals and allow the system to vent and return oil without foaming. Materials are chosen for heat resistance and corrosion protection to withstand the operating environment.
Benefits Include
- Restores stable oil pressure and consistent circulation
- Reduces risk of aeration and oil starvation under high G-loads
- Improves oil cooling and helps protect engine components
Why Oil Tank & Parts Wear and Fail
- Corrosion or internal contamination from moisture and sludge
- Cracks, punctures or impact damage from vibration or debris
- Worn seals, damaged caps or degraded hoses causing leaks
- Blocked breathers or feed lines restricting oil flow
The Importance of Replacing with OEMatch Oil Tank & Parts
Worn or leaking oil tanks and associated parts compromise lubrication and can lead to fluctuating oil pressure, overheating and increased wear. Replacing degraded tanks, seals and hoses restores proper oil management, prevents contamination and helps maintain engine longevity and reliability for road and motorsport use. Choosing correctly sized, well-sealed components reduces the chance of leaks and avoids secondary damage.
