Injector return line

[oklawall]

I have the passenger side injector return line that is starting to leak, if I replace one side I may as well replace both. After all with with 394k I think I would leak a little.

Question any pros or cons of staying with the plastic fittings or switching to the aluminum?

Thanks
Steve

After fighting with mine.
I’d suggest OEM o er aftermarket.
I broke a couple aftermarket reinstalling them.

I have no expertise for the aluminum.
If you stay plastic go OEM.

Went with OEM the 90 deg on the passenger side was made incorrectly. The lip would not catch the clip. Had to take the one off of the old assembly to get the truck going
