C-1 fuel vent hose

[Terry R.]

The 61-62 JG states that the fuel vent hose is smooth,the parts suppiers sale ribbed hose as correct. I've got to believe the JG,(or should I?) will vacumn hose work with the gas vapors? Thanks Terry

My 2 cents

I cannot speak for others who may have also offered this part as a repro. However, when I first made that part nearly 2 decades ago, I used my old 1959 as the authority. That was a hose with one raised ribs. I then extrapolated to other GM model years that used the same assigned GM part number (57-62) as I cheerfully parted out many an old car. Probably not that scientific as this was not the nitpicking group that has emerged via these tomes. We used the GM SAE spec for a fuel resistant rubber.

Can you use vacuum hose for fuel hose? You can do anything you want, however there are different SAE specs for each of these different hosers. Rubber that is not the right spec swells and breaks down when exposed to gasoline. However, if you are building one by the book, then follow the book.

PS I really think half of the info in these tomes is based upon as limited experience as mine and I probably have not seen one percent of production.
