MEC EUR Fuel Tank for Vespa PX Lusso, Model Year 1984 and Later

Without separate lubrication, with mounting for fuel gauge

The MEC EUR fuel tank is designed for Vespa PX Lusso models manufactured in 1984 or later that are operated without a separate lubrication system but are equipped with a fuel gauge. Manufactured in Italy, this tank is modeled after the original factory-installed PX Lusso tank in terms of shape, connections, and mounting points.

This version features a mounting for the metal fuel level sensor used on corresponding PX Lusso models. There is no mounting for a separate oil tank. This makes the tank suitable for engines with mixture lubrication, in which oil and gasoline are mixed directly in the fuel tank.

The tank is designed to accommodate the convenient fuel cap of the PX-Lusso series. The fuel valve, fuel sender, fuel cap, gaskets, and other mounting hardware are not included and must be transferred from the existing tank or purchased separately.

The correct version for PX Lusso models without separate lubrication

There are several versions of the Vespa PX fuel tanks that look similar on the outside but have different connections and mounts. The key distinguishing factors are the separate lubrication system and the type of fuel sender.

The tank offered here is intended for vehicles that do not have a separate oil tank. In these engines, the two-stroke oil is mixed directly into the fuel. At the same time, the tank features the mounting point for the electric fuel gauge of the PX Lusso series.

Features of this tank model

No connection or installation space for a separate oil tank
Mounting point for a fuel level sensor is provided
Designed for the metal fuel level sensor of the corresponding PX-Lusso models
Mounting point for the fuel cap of the PX-Lusso series
Suitable for mixture lubrication without standard separate lubrication

Fuel gauge with metal fuel level sensor

Compared to earlier PX models, the Vespa PX Lusso was equipped with an electric fuel gauge. The fuel sender required for this is located in a separate opening in the fuel tank and transmits the fuel level to the gauge in the steering head.

This fuel tank design is intended for the metal fuel level sensor used in models without a separate lubrication system. The fuel level sensor is not included in the scope of delivery. An existing sensor may be reused, provided it is in good working order and fits the fuel tank design.

Check the fuel level sensor before ordering

This version is intended for the metal fuel level sensor
Tank sensors for models with separate lubrication may differ
Compare the mounting, connector, and sensor design with the existing component
Check the tank sensor seal during installation and replace it if necessary
Check the fuel gauge for proper function and leaks after installation

Without a separate oil tank

In this configuration, there is no additional oil tank located under or next to the fuel tank. The engine oil is added directly in the correct mixing ratio with the gasoline during refueling.

The tank is therefore suitable for both standard PX-Lusso models without separate lubrication and for vehicles that have been modified accordingly, in which the separate oil supply is not used.

Important for mixed lubrication

Vehicles without separate lubrication require a correctly premixed gasoline-oil mixture. The engine must not be operated with pure gasoline.

Follow the engine’s specified mixing ratio
Use suitable two-stroke oil
Measure the oil quantity correctly before refueling
Ensure adequate mixing after refueling
Do not confuse this with a tank designed for standard separate lubrication

PX Lusso-style fuel cap

The tank is designed to accommodate the Vespa PX Lusso fuel cap. This cap features an easy-to-use twist-lock mechanism and differs from the classic flip-top cap found on earlier Vespa large-frame models.

The Lusso closure is easy to open and close and can also be a practical solution for older conversions. However, the fuel cap is not included with this tank.

Easy-to-use twist lock
Fuel cap not included
Check the fuel cap gasket before installation
After installation, check the tank for leaks around the cap

Made in Italy and designed to closely match the original

The MEC EUR tank is manufactured in Italy and is modeled after the factory-installed tank used on the Vespa PX Lusso, EFL, Iris, and Arcobaleno. The mounting, installation position, fuel sender mount, and fuel cap connection are designed to match the corresponding PX Lusso model.

This makes the tank a suitable replacement for a damaged original tank without altering the basic fuel system or the vehicle’s operation.

When should a Vespa fuel tank be replaced?

Fuel tanks can corrode from the inside after several decades. Rust particles then travel through the fuel valve and the fuel hose to the carburetor, where they can clog screens, jets, or passages.

Leaky welds, damaged threads, deformed mounting points, or a severely deteriorated interior coating are also signs that the tank needs to be replaced.

Typical signs of a damaged fuel tank

Rust particles in the fuel filter or carburetor
Brown discoloration of the fuel
Fuel odor in the parked vehicle
Damp spots or fuel stains under the tank
Leaky fuel sender or fuel valve mount
Damaged fuel cap mount
Severe corrosion inside the tank

Conclusion

The MEC EUR tank is the ideal replacement for Vespa PX Lusso models manufactured in 1984 or later that are equipped with an electric fuel gauge but do not have a separate lubrication system.

The design, which closely resembles the original, the mounting for the metal fuel level sensor, and the connection for the convenient PX Lusso fuel cap allow for the replacement of a corroded, leaky, or damaged original fuel tank.

It is important to ensure the correct fit: This tank does not have a mounting for a separate oil tank and is therefore intended exclusively for vehicles with mixed-lubrication. The fuel valve, fuel sender, fuel cap, gaskets, and mounting hardware must be purchased separately or transferred from the existing tank.
