Weber DCOE Idle Jet 45F8

The Weber DCOE Idle Jet 45F8 is a precision-engineered component designed for Weber DCOE and 45 MCHH carburettors. This idle jet features a 0.45mm fuel hole combined with an F8 air bleed specification, providing optimal fuel metering for idle and low-speed operation.

Key Features

Precision Engineering: Manufactured to exact Weber specifications for consistent performance
F8 Air Bleed: Features a 1.2mm air bleed hole that creates a leaner mixture compared to F9 jets but richer than F11 jets
Optimal for Oxygenated Fuel: Recommended when using oxygenated gasoline
Universal Fit: Compatible with all Weber DCOE and 45 MCHH carburettors

Technical Specifications

Fuel Hole Size: 0.45mm (indicated by "45" in part number)
Air Bleed Type: F8 with 1.2mm air hole
Thread: Standard Weber idle jet threading
Material: Precision-machined brass construction

Performance Characteristics

The F8 air bleed specification makes this jet leaner than F9 variants but richer than F11 variants, making it an excellent choice for modern fuel formulations. The 45 fuel size provides moderate fuel flow, suitable for a wide range of engine configurations and operating conditions.

Compatibility

Weber DCOE carburettors (all sizes: 40, 45, 48, 50 DCOE)
Weber 45 MCHH carburettors
Weber DCO/SP variants
