Auxiliary Fuel Tank Question

Hi all,

Is an auxiliary fuel tank from a series 1, 2 compatible with the series 3?
TIA

I would think they are. Series 4 onwards? Maybe not.

Thanks Mudski,
The seller said GQ and series 1 and 2 GU.
You are correct that series 4 changed a few things.

I would have thought the GQ sub would be different to the GU.

So there are some differences that stop a direct swap.
8 - 10 week wait time for a new one so I will wait.
