Might as well do some mods and make it work. Never have seen a whole lot of parts that fit right out of the box...seems I end up having to modify almost everything to make it fit the application correctly...... At least it's a brand new tank and welding on the filler neck won't risk a major explosion or anything.... On one occasion I returned parts that were obviously wrong and had the company RETURN THE SAME PARTS TO ME with their guarantee that "the computer sez it will fit". I'd sure like to see their dang computer come make it fit!!!!!
