Petter A1 question

Hi all.
Could I ask, I've seen A1 with two tanks on, back one for fuel what’s the other for?
Also where can I get a fuel line and sediment bowl from.
Cheers
Tim

Ones with 2 tanks are the paraffin engine, smaller tank is for petrol and is a smaller half round tank holds about half a pint.
Fuel line spares can be found here:

You need 1/4 pipe, the fitting in the carb isn't a BSP thread I don't think and can't remember for sure what it is.
Not all A1 engines had the sediment bowl,
