Just returned from AK where I spent Easter week tearing up the back deck on my gillnetter to replace the leaky ply/glass tanks with aluminum. The shop and I mis communicated regarding the dip tube install and it didn't get done. I have 1" threaded coupler welded to the top of the tank and now need to build a dip tube. Any thoughts on what to use for material and how to construct it? I'm thinking of an alum or stainless bushing purchased from McMaster Carr, necking the 1" down to 1/2" but what do I want to use for the actual tube material? Alum? Rubber hose? Help!
