Just eliminate the problem by installing rigid metal lines, not flex hoses. Since the oil filter mounts on the intake manifold on most stovebolt engines, there's no need for flex hoses. Just use the same copper/nickel tubing that's used for fuel and brake lines, 1/4" outside diameter, with 1/8" pipe to 1/4" inverted flare adapter fittings on both ends. Some people like to put a 360 degree "vibration loop" in each line by wrapping them around a big socket or a piece of pipe, but that's probably not really necessary.
The only reason for using flex lines was for quicker installation, as most of the bypass filters were dealer-installed add-ons after the car or truck was sold.
