Fuel Pump Locking Ring and Seal Kit - Renault Sport Range

Why is replacing the locking ring and seal kit imperative?

Ignoring the replacement of the seal and ring when working on your fuel pump is a costly mistake. By reusing old components, you risk an immediate loss of sealing integrity. The consequences are not just unpleasant (fuel smells in the cabin); they are dangerous: fire risks, faulty tank venting, and failure during technical inspections or competition scrutineering (Group N, Cup, Rally).

This genuine kit is the only reliable solution to secure and seal your fuel sender unit within the tank. It is designed to withstand the stresses of sports chassis and significant vibrations encountered on track or during special stages. It perfectly fits the following models:

• Renault Clio 2 RS (all phases), Clio 2 Group N, and Clio 2 X65 Cup.

Genuine Renault Quality for Your Safety

Aftermarket rings often tend to seize or deform under the effect of fuel vapors. By choosing this genuine Renault product from Optimiz Access, you avoid fuel tank leaks during full fill-ups and maintain the internal pressure required for the optimal operation of your injection system.

FAQ: Frequently Asked Questions about Fuel Tank Sealing

Is a special tool required for installation?

While a specific wrench is recommended to tighten the sender unit nut to the prescribed torque, the thread quality of this original part makes installation much easier compared to lower-quality components.

When should the fuel pump seal be changed?

The seal must be systematically replaced whenever the ring is loosened. The rubber of the sender unit seal swells upon contact with fuel and never returns to its initial shape, making any reuse impossible to guarantee a perfect seal.
