Hi,
Can I ask does anyone know where I could find a replacement for a brass union (mine has snapped), it is the part that connects the 2 stroke pipe from the bottom of the 2 reservoir, into the oil pump.
Kind regards

It looks like that part isn't available separately. You will have to find a 2nd hand pump and rob it of the part you want.

As above.

What you could try is a bit of liquid metal to "stick it back together) and a nail so it doesn't clog up the inside of the Union (keep the inside as open/clean as possible)

No easy way round this one
