I've got a Malaysian steamboat cooker that I want to use in the UK. It
consists of an LPG gas burner with a seperate cooking pot on the top.

If you're wondering what steamboat is, here's an explanation:

The gas inlet for the burner is a serrated metal pipe of about 10mm
external diameter. This appears to be for a rubber hose to be pushed on. I
think an 8mm i.d. low pressure hose will fit nicely.

There is a small lever that adjusts the air after the injector,
bunsen-burner style. I'm hoping that this will give me some leeway
regarding the gas type and pressure.

Here are some pics, which should help to explain things:

What I'm wondering is:

1. propane or butane?

I won't be using this in the winter, so I guess I could use either in
theory. I doubt that the burner will use enough gas to cool a butane
cylinder down too much either.

Does anyone know what gas is typically used for LPG in Malaysia? Everyone
there just refers to it as "LPG" which suggests that they only use one (or
maybe its a mixture).

If I can use either, which would be preferrable?

2. What pressure?

Given that the inlet looks like a simple push-fit using a rubber hose, I
guess that it's going to be low pressure.

Is 37mb for propane and 28mb for butane pretty much standard across the
world?
