Put my old Coleman on the front porch and cooked on it when we had no power. I was having trouble with the Coleman fuel system, but I had a propane converter I bought at least 10 years ago that was still in it's package. It worked great, but man that stove goes through a 1 lb can quick! Used my downtime to order a hose so I can connect a larger tank and a new pump. After I ordered, I recalled that I had a pump behind the work bench. Sure enough, I had 2 I bought at some closeout for $1 each. Swapped it out, cleaned the fuel pipe out, and it's back working like new.
I've always said that if you can go camping, you can survive just about anything.
How did you clean the pipe out?
