Preston,
I don't think you should be that concerned about the fuel injection supply line. The line you have there appears to be the factory updated line with the double crimp cups and NO swivels. The line you should double check is a shorty piece that connects the bottom of the fuel pressure regulator to the fuel tank return line. It's number 11 in this picture

$175 is REALLY steep for this tiny piece. You can rebuild that section with a short piece of SAE 30R3 hose yourself or take it to a hose shop to have a new length of hose crimped on there. The price of the OEM replacement part would lead you to believe it's a preformed 90 degree piece of hose, but it's not. It's a straight length of hose that is turned upward to attach to the regulator.
