I got it, thanks again for trying.
They don't sell reducer hoses by the foot though. Not possible.
to keep this 5 year old thread relevant:
Do you have a difference between your fill neck and your tank inlet?
The pre-77 early bronco neck is 1-3/4. The early bronco tank is 1-3/4. This hose is available at NAPA under part number NBH-1035, and comes in a 3 foot stick for $31.99. The Pleasanton Napa gets hopelessly confused about pricing, and tries to charge $32 per foot. But they do have it in stock.
The Dayco number for a stick of 1-3/4 fuel hose is 80304. Summit has it. PN DAC-80304 and it's $45 for a 3 ft stick.
The Gates number is 24228, for radiator service, and 23968 for gas tank fill necks. Amazon is your friend. $32 for a 3 foot stick.
Oddly enough, I have found that Wild Horses is the most economical way to buy a 13 inch long hose. If you are doing 3 broncos, then it's worth a whole stick.
The only oddball is that 77 fill neck at 2-1/4 and its plastic tank with a 2 inch neck. But anyone running a 77 fuel door deserves whatever pain and anguish that they get. (because I'm jealous and don't have one...)
