Technical Details

• Brand: Porsche.
• Supplied reference: 477919133 / 113919133 / PCG919133A
• Component: fuel level sender gasket.

Symptoms of Fault

• Petrol odour near the sender mounting area.
• Dampness or staining around the sender joint.
• Visible deterioration or damage to the existing gasket.

Why Replacement Matters

Fuel level sender gaskets can deteriorate over time due to age, exposure to petrol and repeated temperature changes.

An old gasket may become hard, flattened, brittle or cracked, reducing its ability to seal effectively.

A damaged fuel sender gasket can allow petrol or fuel vapours to escape from the top of the fuel tank, potentially causing a noticeable petrol smell in the front luggage compartment. Replacing the gasket helps restore a secure seal and reduces the risk of fuel leakage.

FAQs

Will this correct an erratic fuel gauge?
The gasket provides sealing only. Inaccurate readings require checks of the sender, wiring, earth connections and gauge.

Should the seal be checked during sender work?
Yes. Inspect the gasket whenever the sender is disturbed, as an aged or damaged seal can allow fumes or fuel to escape.
