Could anyone help please.As we go away in our van all year round I have bought an all in one diesel heater to supplement our gas fire in the van.As the all in ones are designed to be used outside I need a quick and easy solution for the fitting of the hose between the heater and the van. All the hose I have seen is 75mm black type.I am sure i read somewhere that you can get a quick connect type end cap to make the job of connecting and reconnecting a lot easier.Could anyone point me in the right direction please?If the heater is a success I will probably look at fitting a permanent one next year.Thank you for any help.
