Information
Fuel accumulator.
Replacement fuel accumulator designed to maintain fuel pressure and system integrity on Porsche 911-series engines fitted with CIS / K-Jetronic mechanical fuel injection (e.g., 911 SC, 930 Turbo). Its function is to store pressurized fuel when the engine is running and maintain that pressure when the engine is turned off - ensuring immediate, stable fuel delivery on next start, and preventing vapor lock issues.
Fits:
Porsche 911 SC 1980 -1983
Porsche 930 Turbo 3.0L 1975 - 1976
Porsche 930 Turbo 3.3L 1978 - 1989
Porsche 964 Turbo 3.3L/3.6L 1989 - 1994
Diagram ref no 6.
• With age and repeated pressure cycles, the internal diaphragm can fail or weaken, leading to loss of fuel pressure and possible fuel leaks.
• A failed accumulator means loss of residual pressure - leading to difficult or prolonged cold/hot starts, fuel-starvation, or hesitation under throttle - especially problematic on mechanical injection or turbo models.
• Ensuring a healthy accumulator helps preserve injector life, prevents vapor locking, and ensures reliable performance and drivability - particularly important for classic cars where fuel-system integrity is fragile.
When to replace (common scenarios)
• If the original accumulator shows visible damage, leaks, or drips around the housing or fittings
• When experiencing hard or slow hot starts, hesitation, or fuel-starvation symptoms.
• If the car has been standing for long periods - to avoid internal fuel degradation or diaphragm failure.
• During a fuel-system overhaul, restoration, or maintenance of older Porsche 911 / 930 CIS injection systems
• As preventive maintenance on high-mileage engines to maintain fuel pressure stability and reliability
