Vacuum Hose Identification

[Wsp1992]

My mother's 2005 explorer, with the 4.0 V6, started running rough and throwing codes for both banks running rich. I just found out the culprit is a ruptured hose causing a massive vacuum leak, but the problem is i cannot identify the hose to find a replacement part. attached is images of the hose both with distance to show location and close up to show the rupture. Any ideas for identifying the hose would be greatly appreciated.

Welcome to the forum!

If it's just a piece of standard, round hose, not needing to be molded into a special shape to fit, then just get a bulk piece of hose at an auto parts store. They usually sell hose by the foot, though you could call ahead to see if they have the right inner diameter size. Maybe that's on their website, I don't know. I am not suggesting with the example link below that yours is 1/2". I can't measure it from here. I'd cut the original hose to get an inner diameter measurement where it hasn't been stretched from being installed.

I like to use hose clamps too, but I don't see one on your hose.... your call. I'd try warming the hose a bit, maybe some silicone grease to help it slide on, since any plastic nipples it slides onto might be brittle after years of being in an engine bay, but especially if you use grease, then I'd want a hose clamp.

EDIT: Best practice would be to not use any radiator, heater, or vac hose including the one I linked, because fuel (vapor in this case) hose is typically a nitrile rubber aka NBR with good fuel resistance while radiator and other EDPM rubber hoses do not have good fuel resistance. IDK how long it would take for that difference to matter since this is just vapors rather than direct liquid contact, but I doubt that the original hose used the same kind of rubber as radiator hose, more likely NBR. You might still be able to get NBR hose by the foot at some auto parts stores.

here is an image of where the other end of the hose attaches, it ends at the top attachment point:

That looks like your vapor canister purge valve.

This "might" be it... but see all related parts on the 2nd link too.

i just need a part number for the hose because i'd need specific fittings and it's better to use the new stuff. can't find a diagram for the life of me

The 2nd link I posted may be about as good as it gets, shows the 3 vapor system hoses, one from intake to purge valve, one from purge valve to vapor canister, and one from vapor canister to gas tank as far as I can tell from their terrible drawings... so my best guess is that's part # 1L2Z-9K318-AA

Those hoses are for fuel vapors only. Yours looks like it might have gotten liquid gas through it. Check the other hoses for liquid fuel in them.
By overfilling tank with fuel, liquid gas can get into that system and why the manufacturer says to fill tank only to the first click shut off at pump, no topping off to the brim.
