Porsche 924 Fuel Hose - Accumulator to Fuel Line

Accurate Fuel Delivery and System Reliability

The fuel hose from the accumulator to the fuel line is an essential part of the Porsche 924 fuel delivery system. It connects the fuel accumulator to the main fuel line, allowing pressurised fuel to flow consistently under varying engine demands.

Fits:

• Porsche 924 2.0L 1979-85
• Porsche 924 Turbo 2.0L 1979-81
• Porsche 924 Turbo 2.0L 1982-84
• Porsche 924 Carrera GT 2.0L 1981
• Porsche 924 Carrera GTS 2.0L 1982

This hose plays a crucial role in maintaining correct fuel pressure, stabilising fuel delivery and preventing fuel leaks.

What This Fuel Hose Does

In the Porsche 924, the fuel system includes a fuel accumulator that smooths pressure fluctuations and ensures steady fuel supply, especially at idle and under load. This hose connects the accumulator to the main fuel line and:

• Maintains sealed fuel transfer under pressure
• Allows the fuel accumulator to do its pressure-stabilising function
• Prevents fuel spray and loss under engine vibration
• Helps maintain consistent fuel pressure to injectors

Without a reliable accumulator-to-fuel-line hose, the fuel system cannot sustain proper pressure. That affects engine performance, idle quality and efficiency.

Why Fuel Hoses Fail

Fuel hoses are exposed to harsh conditions over time including constant fuel contact, heat cycling, vibration and environmental contamination. Common reasons this fuel hose fails include:

• Rubber hardening and cracking with age
• Fuel permeation that degrades inner hose layers
• Exposure to heat from the engine bay
• Swelling or softening from prolonged fuel contact
• Chafing or abrasion against surrounding components

As the hose ages, it can develop leaks, bulges or internal collapse, impairing fuel flow and pressure.

When You Should Replace This Fuel Hose

You should consider replacing the fuel hose if you observe any of the following:

• Visible cracks, splits or bulges in the hose
• Fuel smell while the engine is running or parked
• Fuel leaks under the vehicle around the fuel rail or accumulator
• Poor idle quality, hesitation or stalling
• Fuel pressure loss or drop under load 
• Regular maintenance on original or aged fuel system components

Because fuel leaks pose both performance and safety risks, replacing this hose is essential when deterioration is evident or if it has never been renewed on an older Porsche 924.
