Vacuum Leak Finally Located??????

I did some work to my vacuum and EVAP system today. I need the two black elbows in the photo below, but cannot find these in any illustrations in my 2003 Parts List for some reason. (Probably because I am not looking hard enough, duh...)

The front one seems to have a burnt or melted off bit at the end where (I am hoping) leak was probably happening. It was not fully on the nipple either, so I think the melted off part was allowing fumes to escape or air to enter the system. (Not sure what these lines do. Sorry for my craptacular descriptions.)

I replaced the rubber grommets and the two elbow valves in the valve cover since the rear one had a lot of old oil gunk buildup all over. I figured It must be leaking, so I would swap both out. I also replaced both those lines (to the intake tube and to the manifold) as well as the large line from the manifold to the brake booster. I then replaced the Vapor Canister Purge Solenoid. When I got it off its mount I discovered the screwed up, dry rotted rubber elbow connectors on the manifold behind the Purge Solenoid.

Hope someone (like Jerry Bransford) can tell me exactly what the front two of these lines on the side of the intake manifold do and the part numbers for the elbows. Looking for actual Mopar part numbers and names.

The brown one (closest to firewall) is already on order. (It is the HVAC vacuum line and valve that runs from he driver side manifold across the firewall, into the HVAC unit in the dash, and down to the EVAP canister living in the passenger side fender. I will have it in a few days. That just leaves these two dry rotted bits of nastiness for this round of my leak search.

I want OEM Mopar, despite the stupid-high prices. I know I can just use rubber vacuum line, but would prefer to use that as a fallback if I strike out with the Mopar bits.

Thanks.

Bump.

Anyone?

Any recommendations for replacement elbow? I am guessing these both will need to be fuel-safe and not just generic rubber. Is this correct? I have heard that Dorman's Help brand should be avoided because they will rot really fast. Will AutoZone or O'Reilly carry this sort of thing from some place like Goodyear?
