Diagram ref no 25
What This Product Does
This filter element screens debris and contamination within the fuel tank before fuel circulates through the delivery system. Maintaining an unrestricted supply helps protect the fuel pump and downstream injection or carburettor components.
Functions
- Filters particles from fuel leaving the tank
- Helps protect the fuel pump from contamination
- Supports consistent fuel flow through the delivery system
- Forms part of the front fuel tank assembly
Technical Details
- Part number: 91120114100
- Component type: fuel tank filter element
- Installation location: front fuel tank assembly
Symptoms of Fault
- Hesitation or reduced power under load
- Long cranking or difficult starting
- Restricted fuel flow
- Fuel pump operating more noisily than usual
- Repeated contamination found elsewhere in the fuel system
- Visible debris or deterioration identified during tank servicing
Why Replacement Matters
An obstructed filter can restrict the supply of fuel and place additional demand on the pump. Replacement may be appropriate during scheduled fuel-system maintenance, tank refurbishment or diagnosis of contamination and flow problems. Inspect associated connections and sealing components during installation.
FAQs
- Is this the engine-bay fuel filter?
No. This part is the filter element associated with the front fuel tank assembly. - When should it be inspected?
Inspection is advisable when servicing the tank, investigating restricted fuel flow or dealing with contamination after prolonged storage. - Can a blocked element affect the fuel pump?
Restricted flow can make the pump work harder and may contribute to noisy operation or fuel-delivery problems. - Does it fit every classic 911?
No. Confirm part number 91120114100 against the vehicle model, production year and fuel-system arrangement before installation.

This OE Match fuel filter follows the original filter format for routine servicing and fuel-system maintenance.
Fits
- Porsche 911 (930) Turbo 1975-80
What This Product Does
The filter captures particles carried in the petrol supply before they reach downstream injection components. Dirt, rust and deposits can accumulate within the filter during use, making it a service item rather than a permanent fuel-system component.
Functions
- Traps fuel-borne dirt and debris.
- Helps limit contamination reaching injection components.
- Provides a renewable filtration element within the fuel supply.
Technical Details
- Brand: OE Match.
- Part reference: 93011013900.
- Identified in the rear fuel-system assembly for 911 Turbo 1978–83
- Also identified in the 911 Turbo 1975 onwards K-JETRONIC fuel-system diagram.
- Replacement following the original filter style.
Symptoms of Fault
- Hesitation when the engine is under load.
- Extended cranking before starting.
- Uneven running or surging.
- Reduced engine response at higher revs.
- Corrosion on the housing or seepage around connections.
These signs can have other causes. Check fuel delivery and ignition condition before attributing a running problem to the filter alone.
Why Replacement Matters
Accumulated contamination can restrict fuel passage through an ageing filter. Renewal is appropriate at the vehicle's specified service interval, when blockage is confirmed, or during investigation of contaminated fuel after storage. Inspect adjacent hoses, unions and seals at the same time rather than assuming that changing the filter will resolve every fuel-system fault.
FAQs
- When is replacement due?
Use the service schedule for the specific vehicle and review its maintenance history. - What if a replacement becomes blocked soon afterwards?
Investigate debris in the tank and deterioration inside the fuel lines. - Should connection seals be renewed?
Check the fitting requirements and replace sealing washers or other seals where specified.
Check fitment for your specific vehicle (model, year, engine) before ordering.

OEMatch Fuel Filters — Fit, Function, Confidence
OEMatch fuel filters for Porsche models support clean fuel delivery and consistent running across everyday use and more demanding driving. These components are part of routine maintenance and play a key role in helping protect the fuel system and engine over time.
- Inline and in-tank fuel filters for Porsche applications
- Cartridge and spin-on filter elements for different model generations
- Filters for petrol and diesel Porsche engines where applicable
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original fuel filters. OE (Original Equipment) refers to parts matching original specifications for the fuel filters and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM fuel filters engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
OEMatch fuel filters help maintain correct filtration levels by separating contaminants from the fuel before it reaches critical components. Positioned in line with the fuel system, they support smooth running by helping to keep injectors and pumps free from particles and moisture that can accumulate in the tank. Many owners search for genuine or OEM fuel filters; these are direct-fit alternatives designed to match the original form, fit and function.
- Support clean fuel delivery to the engine
- Help reduce the risk of deposits in injectors and pumps
- Contribute to smoother running when combined with regular servicing
- Made to original-spec dimensions for Porsche applications
- Available for a wide span of Porsche generations and engine types
- Age-related degradation of the filter media
- Contaminants such as rust, dirt or tank residue building up over time
- Poor fuel quality or moisture in stored fuel
- Skipped service intervals leading to restricted flow
- Previous repairs leaving contamination within the fuel system
Replacing a tired or blocked fuel filter with an OEMatch component helps maintain consistent fuel flow and supports stable engine operation in Porsche vehicles. Regular renewal as part of scheduled servicing can assist in protecting sensitive high-pressure components, especially on later injection systems. For older Porsche models, timely replacement can also help reduce the risk of debris-related issues developing in fuel lines or injectors.
- Porsche-focused coverage across multiple model generations
- Direct-fit replacements engineered to match original dimensions and tolerances
- Fits original mounting points and clearances
- Compatible with factory systems and sensors where fitted
- Supported by OEMatch’s focus on components for Porsche applications
