need some advice, running 3/8" fuel line, how to run, what to use

You can buy it buy the foot for $3.50 or less. There's no need to buy a whole 25' roll.

Then let’s see your current source at that price, the brand of hose you’re using, and tell us how many feet you actually needed.

Might as well throw in the cost of the proper connectors and hose straps while you’re at it.
