Fuel Filler neck and vent hose for dual tanks

[datmony]

Does anyone know where to get these at? This is the hose that runs from the into the tank from where you would fill the tank at the gas pump. I thought Napa or someone would at least have some straight hose that I would be able to use but the smallest size they have is 1-1/2" ID where as the hose that came off has an ID of only 1-3/8". I have been looking all over the web as well and I have not been able to find anything that small. I would prefer one with a bend but could likely live with a straight one if that is all there is. Thanks in advance.
