My lines (the clear lines leading to and from the main fuel filter) are quite hard/brittle. i have been able to find a replacement for one, but not the other. Replacements come with the brass fittings at each end, but my question here is:
Is it not possible to retain the fittings and simply find similar tubing, sliding it on to existing fittings? If so, would anyone be able to provide me with specs/links/recommendations for sourcing this tubing?

Thanks,
Brice
