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.

What This Fuel Hose Does

In the Porsche 924, fuel flows from the tank through the main fuel line and then to the fuel filter. The fuel filter removes debris and contaminants before the fuel continues on to the fuel pump and injectors.

This hose serves to:

• Connect the fuel line to the fuel filter securely
• Maintain sealed fuel transmission under pressure
• Support consistent fuel flow to the filter
• Prevent fuel leaks that can cause performance issues and safety hazards

Without a properly sealing hose between the fuel line and fuel filter, fuel delivery can be disrupted, leading to poor engine performance and potential system failure.

Why Fuel Hoses Fail

Fuel hoses are constantly exposed to harsh operating conditions, including fuel contact, heat, vibration and movement. Common reasons this fuel hose fails include:

• Rubber hardening and cracking due to age and heat cycling
• Fuel permeation that weakens hose integrity
• Swelling or softening from prolonged contact with fuel
• Abrasion or chafing against nearby components
• Environmental exposure and chemical degradation

Over time, these factors can cause the hose to crack, split or collapse internally, reducing fuel flow and increasing the risk of fuel leaks.

When You Should Replace This Fuel Hose

You should consider replacing this fuel line to fuel filter hose if you notice any of the following:

• Visible cracks, splits or deformation in the hose
• Fuel smell around the engine or along the fuel line
• Fuel leaks near the hose, filter or fuel line connections
