Perfect fit fuel lines 02 Avalanche 2500 !

I bought the complete set of fuel lines for a 02 Avalanche 2500. All high quality OEM style product. It took longer to remove old lines than to install new ones. Remember to install new fuel pumps and filters during installation. Great Canadian company where I will buy all my lines from.

Easy install and 100% satisfied. Had to make some modifications to hook up to an aftermarket cooler but that was to be expected.
