Overflow hose for fuel filler neck.
The overflow hose provides a vent path for fuel vapours and excess pressure from the fuel filler neck to the tank vent/evaporative system, preventing pressure buildup and aiding smooth refuelling without backflow or spills.

Fits:
Porsche 911 1978 - 1989
Porsche 964 1989 - 1994
Porsche 993 1994 - 1998

Diagram ref no 24

The hose fits between the fuel filler neck and the fuel tank vent/overflow outlet, allowing controlled relief of fuel vapours and pressure during refuelling and normal operation. A compromised or deteriorated hose can lead to fuel vapour leaks, poor venting, fuel smell at the rear of the vehicle, or difficulty refuelling due to trapped pressure.

This OE Match hose offers a direct replacement solution for restoration, maintenance, or repair when the original hose shows signs of age or damage.

Function:
•  Ensures proper venting of fuel fumes and pressure from the filler neck
•  Maintains correct fuel system breather operation
•  Prevents fuel vapour leaks and associated odours
•  Durable, fuel-resistant construction for long service life

The fuel filler overflow/vent hose plays a small but important role in maintaining proper fuel system behaviour. A cracked, hardened, or leaking hose can cause fuel vapour smells, trapped pressure that makes refuelling difficult, and potential environmental or safety issues. Replacing it with an OE Match hose restores correct venting and refuelling behaviour while helping keep the fuel system sealed and odour free.

When to replace:
•  Visible cracking, swelling, or brittleness of the hose
•  Noticeable fuel vapour smell near filler area
•  Difficulty filling the tank (pressure backflow)
•  During restoration or fuel system servicing
•  If original hose shows age-related deterioration
