I have a slight leak in the tube connecting the city water inlet to the T-fitting on the discharge side of my pump. I wanted to replace that 20" hose but I cannot seem to find the right one. It has 1/2" FIP fittings on both sides but the actual hose diameter looks like it is bigger than 1/2". It looks closer to 3/4" from the outside. Now I realize the outside diameter is not the actual diameter. I went to Menards and they have a household faucet line that has 1/2" FIP on both ends but the outside diameter of the hose is almost half the size of the original line in my camper. I have looked all over the internet and cannot find anything. Does any one have any suggestions or know where I can get this hose. I have a picture attached. Any help would be great!
