I love the esoteric intricacies of classic procars... There is a rubber hose that leads from the fuel filler neck to the gas tank on my 1970 Cadillac Superior. It has begun to leak. I went to NAPA today, and they don't have anything with a 90 degree bend in it that is fuel safe. They had a flex hose that was wire wound inside, but it too folded when arced to 90 degrees. Any suggestions on where to find a fuel-safe hose that has a 90 degree bend in it? Judging by how low the hose attaches to the tank, this hose must be constantly filled, so it is no surprise the old hose is starting to leak. Damn new gas formulations.
