mGood quality fuel tubing- will not significantly shrink, harden, or any other negative reaction over time or when exposed to stale or moisture-absorbed ethanol/gas fuels. (People say ethanol kills engines/rubber parts- but it is mainly caused by moisture, and the fact that ethanol strongly absorbs it into your fuel)
Can be purchased as multiple quantities, in which case I will send your total length of tubing as one continuous piece- so that you could have enough length for any/all other applications.
