[QUOTE="machoheadgames, post: 429602, member: 18789"] It’s to clear the upper idler which all of them have. The AC adds a lower idler on the timing cover…at least in every single belt diagram, online catalog, etc that I’ve ever seen. You sure the ones you saw without the tube were 91+ 4.0 & 2.5? Older pumps like the 4.2 I believe had cast bulbs for the hoses to clamp to. Older CJ engines definitely did. All the MPFI engines though should have had the pipe. And yeah at the end of the day probably doesn’t make a difference. The FSM shows the flow to be a certain way and the hoses make sure that happens but I’m sure it makes no heating difference. It’s also not that huge of a step from 5/8 to 3/4 so you may have gotten the hoses correct and just stretched the 5/8 over the 3/4 locations. End of the day it doesn’t matter, I only buy the molded hoses because they are easy and $10 each which is cheap compared to all the other garbage I’ve bought lol. [/QUOTE]
