Replacing ps return hose

The return hose in question is the furthermost forward one (2 ps low pressure fittings-one is behind the other).
Snakes up and around and probably squeezes in between frame rail and headers, making top side service impossible?
I pulled the wheel liner off and still cant make out which line it is.
Is it just a barb fitting on the rack end?
Any tips on replacing this line?

Ps, noticed over the winter the line was severly dry rotted and cracked. Driving home from work today i think gee i really need to buckle down and replace that line. 15 mins later i feel the ps give out. Check it oit, yup line ruptured.
