I have 12' of hose between a cylinder and a weber Q, the hose makes a few loops. A few summers ago I left the cylinder valve open for a week in 110F high temps. When I went to use it, oil leaked out of the air intake downstream from the Q's regulator. I disconnected the hose and used the propane to blow out the hose. If the Q's regulator was at the cylinder I likely would never had this issue.
Response from Mr. Heater: When you connect any of our Buddy model heaters to a remote propane tank, that tank can have over 120 PSI of pressure inside it.This high pressure in the rubber hose connected to the heater can squeeze a plasticizer or an oil out of the rubber in the hose and once it gets into the heater it is trapped and will plug up the tubes and cause the heater to be an unreliable unit.We came up with a fuel filter to prevent this oily substance from getting into the heater when using a high pressure hose.The hose manufacturers came up with a hose that doesn’t have the plasticizers in it so NO filter is needed (our part number for this plasticizer hose is F273704).BUT the draw back with this hose is with no plasticizers in the rubber it causes the hose to be very stiff especially in cold weather.
