Fuel Line.
The Porsche Fuel Line is a genuine OEM replacement component designed for Porsche 911 (964) models from 1989–1994. This precision-engineered line ensures safe, efficient, and leak-free fuel delivery within the L-Jetronic fuel injection system.

Fits:

• Porsche 964 (911) C2 1989-93
• Porsche 964 (911) C4 1989-93
• Porsche 964 (911) RS 3.6L 1991-93
• Porsche 964 (911) RS 3.8L 1991-93

What This Product Does:

It’s a rigid or semi-rigid fuel feed line that carries fuel from the supply source (fuel pump / fuel filter) to the injector rails or part of the fuel injection system.
It must maintain fuel pressure and avoid leaks, kinks, or chafing. It’ll be routed along engine bay or firewall areas, often exposed to heat and vibration, so material durability is important.

Symptoms Of A Failing / Damaged Fuel Line:

• Fuel smell in engine bay, particularly under load or acceleration.
  
• Visible fuel leak or seepage along the line or fittings.
  
• Poor performance, hesitation, or stumbling when accelerating, because fuel supply or pressure is not consistent.
  
• Hard starting if fuel isn’t reaching injectors properly.
  
• Engine Light or fault codes related to fuel pressure, injector supply, or lean mixture.
  
• Spitting / sputtering if air is drawn into the fuel feed or fuel delivery is compromised.
  
  

Why Replacement Matters:

• Restores safe, leak-free fuel delivery — fuel leaks are a fire hazard and dangerous.
• Ensures correct fuel pressure for proper engine performance and driveability.
• Prevents damage or stress to other fuel system components (fuel pump, regulator, injectors) that might struggle if supply is inconsistent.
• Maintains reliability & prevents breakdowns — a failed fuel line could strand you or lead to more costly secondary damage.
