Q: I bought this filter but it does not connect to my Big Buddy hose model F271803. why do you state that this filter works will all Mr Heater hoses?

6 months ago
1 Answer
  • A: Thank you for your inquiry. The F271803 is a quick connect hose that doesn't require a fuel filter. The quick connect fitting on it is unique from all other Buddy hoses, and is the only one that won't connect to this filter. Have a great day!

Q: I ordered both the hose and filter but the filter won't be here for a few more days, would it be okay to run the heater without the filter a couple of days.

4 years ago
1 Answer
  • A: Thank you for your inquiry. Without the filter, oils from the hose can find their way into the fuel lines of the heater, which can cause issues. There isn't a set time for how long it will take this to happen, so we don't recommend doing so at all.

Big buddy w/20lb & 12' hose and filter is the best

8 years ago
This is an absolute must if you plan on using the large LP tank like a 20 pound cylinder or larger, the particulate matter found in the production of tanks is large enough to plug the gas orifice preventing your product from working and when you need to heat the most you don't have it because you didn't listen to me and buy the frickin filter like I told you! Also get the 12' hose to complete the best most reliable off grid heat source . I've been using a little buddy for 15 years just about or round the time when it first came out on the market accents upgraded to the big buddy green one and it's working perfect I bought the 110 adapter for the onboard Fan , are use it sparingly to extend the life of the fan as my application the radio he practically roasts me out of my log cabin

You wasted my time

4 years ago
I ordered this along with a Mr Heater space heater and the AC adaptor. You cancelled everything except the fuel filters, so my review is that I won’t be wasting my time buying anything from you again.
