Here is my guess from previous situations I have dealth with. This looks like a repair made by a previous owner,(as you can see from the 2 different screw collars used, one of them obviously not stainless) and there is no reason to have a splice at this location. Standard water fill lines for these units comes in two sizes, 1-3/8" and 1-1/4". If the fill hose is a 1-3/8" and you try to make a splice using a barbed plastic fittings union from your local hardware store you will end up using a 1-1/4" standard hose fitting and it will be impossible to seal and the gap will always remain. Check with your local rv or marine parts supplier and get the right 1-3/8" I.D. fitting, use 2 full stainless collar of proper diameter and your problem should be solved, assuming you have a 1-3/8 line. Hope this is your case
