300A Gas Mixer Hat Adaptor - Nissan Patrol Y60 GQ TB42s Carburettor

This gas mixer hat adaptor is designed to fit directly on top of the factory carburettor of a TB42s petrol engine. It provides a secure, sealed mounting point for a 300A-style LPG gas mixer. For any 4x4 owner performing a dual-fuel conversion on their carburettor-equipped GQ Patrol, this part is essential for a professional and reliable installation, ensuring the LPG system integrates perfectly with the original engine intake.

Ignoring the need for a purpose-built adaptor can lead to significant problems. A poorly sealed or fabricated solution will create vacuum leaks, resulting in a lean air/fuel mixture. This causes poor engine performance, hesitation, difficulty tuning, and can potentially lead to long-term engine damage. A proper adaptor ensures a stable, reliable fuel system on both petrol and LPG.
