This was more than enough length and worked perfect for replacing fuel lines that were rusted out after 26 years of abuse due to winter snow and salt.

It fit. If 5/16 is what your looking for then 5/16 is what you will get

Good line for repairs.... works well with compression couplings...

The parts store wanted to change me a few dollars per foot for this nylon line so this was a much lower cost solution. It arrived in a couple of days so I didn't have to wait too long either. It is the same name brand Dorman fuel line as at the parts store as well. I used this to replace my corroded, rusted steel fuel lines. It was very easy to cut and work with and will never corrode or rust through. Unlike the steel lines, it won't tolerate being routed at more than 45 degree bend as it will kink if bent more than about 45 degrees. My gas tank had nylon lines being routed out of the fuel pump and when I connected these to my new nylon lines I could get a 90 degree bend there only. This was enough for me to successfully route the rest of the lines with only 45 degree bends of less. I did have to purchase and put a heat shield sheath around these fuel lines where they where routed near the exhaust pipes. The original steel fuel lines had no heat shield.

OK product.
