I understand your concern about your 2-burner Coleman stove slipping. Here's an article with a very simple and cheap DIY on how to prevent your Coleman camping stove from sliding. Coleman 2 Burner Camping Stove DIY Non Slip Bottom Traipsing Around

My searches of the internet indicate that this appliance is a multi-fuel appliance.
It is supplied with a gas bottle - for use with butane fuel
(see http://www.dx.com/p/campsor-9-split-type-camping-oil-gas-fuel-stove-silver-red-126914#.U0we9nlOVjo )
Read the reviews on that webpage for reviwers experiences with different types of fuel. Diesel doesn't work, it seems, but kerosenr and unleaded gasoline (petrol) work ok. You may need different connector for gaseous fuel and liquid fuels.
Coleman Naptha fuel apparently works well.
I hope this information is some use.

Is there a reason or a need? I cannot imagine why you would want to, except as a point of interest for your camp kitchen. A new propane stove would work better and not cost all that much, relative to the work and cost of putting fittings, pipes and burners into the old stove box.

Multifuel stoves can accommodate various fuels including white gas, unleaded auto gasoline, kerosene, jet fuel and diesel. They tend to cost more than any other camping stove.

It is an old one, Propane? or gasoline/camp stove fuel?

If propane and will not remain lit- replace the thremocouple- that thing beside the pilot flame that does not seem to do anything- it holds the gas valve open when flame is present.

If gasoline/camp stove fuel and will not light or does not stay lit- clean the "generator" which is under the asbestos shell. It is not even acknowledged by Coleman anymore.

The old Coleman Camp Stoves used White Gasoline or petrol. However, that is no longer approved and has been banned as a safety issue for some years now. With that said, you have a real antique and if it's in decent condition, is worth some money to collectors of old camping equipment. You may want to rethink giving it away (because, it can't be used as a camp stove any longer) and sell it to an antique dealer or collector.

I hope this helped you and thanks for choosing FixYa.

Ozark Trail GCT1705W Portable 2-Burner Double Propane Gas Stove replacement parts ARE NOT AVALABLE ANYWHERE !the only thing you can do is get a coleman regulator part number 5430 regulator .cut you tube and hose clamp it to the new one ! use a 5/16 fuel line
use 4 clamps on each sides ! these stoves are junk and we are bot stuck with them :( this way beats throwing the piece of junk out ,then you will have a usable stove with a coleman regulator

There is water in your fuel. Drain the tank and flush it out with denatured alcohol. Refill with fresh fuel.
