Had some issues getting the coupler on the hot side pipe fully sat.. Thought I had it on there,, but the truck had other thoughts lol.. Had to take it back apart, and once I got it fully sat (using a rubber mallet and block of wood) it was noticeably more secure. Wish I had done it the first time like that lol.. I found the hoses, coupling with the metal pipes very hard to work with, but now that they're on,,, they're badass.. Thanks!
