Fuel Pressure Line to Fuel Accumulator. Porsche 911 T-K / 911 / 911S 1972-74  ❭  9113560740Y

Fuel Pressure Line – To Fuel Accumulator

High-quality replacement fuel pressure line designed for Porsche 911 T-K, 911, and 911S models equipped with Bosch CIS (K-Jetronic) fuel injection systems.

This line connects the fuel system to the fuel accumulator, a critical component responsible for stabilising fuel pressure and ensuring smooth engine operation—particularly during starting and transient load conditions.

Fits:

• Porsche 911 T-K 2.4L - 1972-73
• Porsche 911 2.7L - 1974
• Porsche 911 S 2.7L - 1974

As part of the high-pressure CIS fuel network, this line plays a vital role in maintaining consistent fuel delivery across the entire system.

Manufactured to OEM specifications, it provides precise fitment and durability, making it ideal for maintenance, repair, or full fuel system restoration.

Key Features

• Direct replacement fuel pressure line to accumulator
• Suitable for Porsche 911 T / 911 / 911S (CIS systems)
• Designed for high-pressure fuel delivery
• OEM-correct routing and fitment
• Resistant to fuel, heat, and pressure
• Ideal for single replacement or full system rebuild

Part of a Complete CIS Fuel System

This fuel pressure line operates within a fully integrated CIS fuel delivery system, including:

• Fuel pump
• Fuel accumulator
• Fuel metering head
• Injector lines (to each cylinder)
• Fuel return lines
• Fuel injectors

Each component is interconnected—meaning performance issues are often linked across multiple parts.

Why Replace Fuel Pressure Lines as a System

Due to age and operating conditions, CIS fuel lines often degrade together.

Common reasons to replace include:

• Pressure loss or inconsistent fuel delivery
• Hard starting or poor warm running
• Fuel leaks under pressure
• Age-related cracking or internal restriction

For best results, inspect or replace multiple lines together to restore full system performance.
