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.

Product Information

Porsche 924 Fuel Hose - Fuel Line to Fuel Filter

Critical Fuel Delivery Hose for Porsche 924

The fuel hose from the fuel line to the fuel filter is an integral component of the Porsche 924 fuel delivery system. It connects the engine’s main fuel line to the fuel filter, ensuring a clean, continuous flow of fuel to the engine.

This hose maintains sealed fuel transfer and helps protect the fuel system from premature wear, contamination and pressure loss.

Fits:

Porsche 924 2.0L 1979-85
Porsche 924 Turbo 2.0L 1979-81
Porsche 924 Turbo 2.0L 1982-84

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
Poor engine performance such as hesitation or misfire
Fuel pressure loss on acceleration or idle
Original hose has never been replaced on an older Porsche 924

Replacing this hose proactively during maintenance avoids fuel supply interruption and eliminates a common source of fuel leaks.

What This Fuel Hose Does

In the Porsche 924, the fuel pump draws fuel from the tank and sends it toward the engine. Before entering the main fuel line and accumulator, the fuel must travel through a dedicated hose that connects the pump to the accumulator.

The fuel pump to accumulator hose performs the following functions:

Transfers pressurised fuel from the pump to the accumulator
Supports stable fuel pressure throughout the system
Prevents fuel leakage at the connection point
Enables the accumulator to smooth pressure fluctuations
Ensures consistent fuel delivery under engine load

Without a properly functioning hose in this position, fuel pressure can drop, leading to engine performance issues and potential stalling.

Why Fuel Hoses Fail

Fuel hoses are exposed to constant fuel contact, heat and vibration. Over time, these stresses can cause the hose to deteriorate. Common failure causes include:

Rubber hardening and cracking from age and heat cycling
Fuel permeation that weakens internal hose structure
Swelling or softening due to prolonged fuel exposure
Vibration or chafing against surrounding components
Environmental degradation or contamination

When fuel hoses degrade, they can split, bulge or collapse internally, disrupting fuel flow and compromising fuel pressure.

When You Should Replace This Fuel Hose

You should replace the fuel pump to accumulator hose if you see any of the following symptoms:

Visible cracks, splits or deformation in the hose material
Fuel smell around the fuel pump or under the vehicle
Fuel leaks at the hose or connection points
Engine hesitation, stumbling or rough running under load
Loss of fuel pressure during acceleration or idle
Old or original hose showing age on a high-mileage Porsche 924

Replacing the hose proactively as part of routine fuel system maintenance can prevent sudden fuel pressure loss and avoid damage to other fuel system components.
