Genuine Nissan Fuel Pump / Fuel Sender O-Ring Seal – Skyline GT-R Silvia – 17342-79900
Ensure your Nissan's fuel tank remains properly sealed with the Genuine OEM Nissan Fuel Pump / Fuel Sender O-Ring Seal – 17342-79900, a factory replacement sealing component designed for compatible Nissan fuel pump and fuel sender assemblies.
This genuine Nissan O-ring forms a seal between the fuel tank and the applicable fuel pump or fuel sender assembly, helping prevent fuel leaks and fuel vapour from escaping around the tank opening.
Over time, original fuel tank seals can become compressed, hardened, brittle or damaged due to age, fuel exposure and repeated removal of the pump or sender assembly. Reusing an old seal during fuel system servicing may increase the risk of an improper seal or subsequent fuel leakage.
Manufactured to Nissan's original equipment specifications, this genuine replacement provides factory-style fitment and sealing performance for compatible applications.
Whether you're upgrading the fuel pump in your Skyline GT-R, replacing a faulty fuel sender in your Silvia or carrying out fuel tank maintenance, fitting a new genuine Nissan O-ring is an important part of completing the job correctly.

Why Replace Your Fuel Pump O-Ring?
The fuel pump and sender assembly seal is an important component of the fuel tank system.
Its purpose is to create a seal between the fuel tank opening and the applicable pump or sender assembly, reducing the risk of fuel leakage and vapour escaping.
Over time, the original O-ring may lose elasticity or become permanently compressed, preventing it from sealing correctly when reinstalled.
Common reasons for replacement include:
- Removing or replacing the factory fuel pump assembly
- Installing an upgraded fuel pump
- Replacing or servicing the fuel level sender
- Repairing fuel leaks around the tank opening
- Replacing a hardened, flattened or damaged original seal
- Restoring the factory fuel system during a vehicle rebuild
Using a fresh genuine Nissan seal during compatible fuel system servicing helps reduce the risk of leaks caused by reusing an aged or damaged O-ring.
Recommended During Fuel Pump Upgrades
Fuel pump upgrades are common on modified Nissan performance vehicles, particularly turbocharged Skyline GT-R and Silvia models.
Whenever the fuel pump or sender assembly is removed from the tank, it's a good opportunity to inspect the original seal and replace it where required.
This genuine Nissan O-ring is a useful addition to:
- Factory fuel pump replacements
- Aftermarket fuel pump upgrades using compatible factory assemblies
- Fuel sender replacements
- Fuel tank cleaning and servicing
- Fuel system restorations
- Repairs involving fuel leaks around the pump or sender opening
Important Installation Information
Fuel system servicing must be carried out carefully due to the presence of flammable fuel and fuel vapours.
Before installation, ensure the vehicle is in a well-ventilated area away from ignition sources and follow the applicable Nissan factory workshop procedures for fuel system servicing.
Inspect the fuel tank sealing surface, pump or sender flange and retaining components for damage or contamination.
Ensure the replacement O-ring is correctly positioned and is not twisted, pinched or damaged during assembly.
After installation, check the assembly for correct seating and verify that no fuel leaks are present before returning the vehicle to service.
Professional installation is recommended.
