A rodent chewed through a hard-to-reach vacuum line. As the picture shows it is a red plastic line that I am unfamiliar with and don't know exactly what I would call it for a replacement part. It is also broken right next to a joint/connector that I don't know if needs replacing as well.
Any help would be appreciated. First time post.


Red vacuum line chewed through by a mouse or rat.

 

Welcome to the forum

Just use rubber vacuum lines of correct size to repair it

Take that one rubber connector off and use it to get correct size for red plastic line, a rubber hose that slides over it snugly doesn't have to be super tight, its vacuum hose not a pressure hose, then use a small to larger splice connector to match the size of other hose, IF the red size won't stretch out enough to fit it, it might
Auto parts stores will have vacuum hoses of different sizes, by the Foot, and a box full of splices and "T"s of different sizes, this is a common repair issue
So you wouldn't use the current rubber piece except for sizing

Car makers use hard plastic hoses because they are maybe 1 tenth the cost of rubber hoses, and they can also be pre-bent and color coded for easier assembly at the factory, they are not "better" just cheaper and easier, lol

 

RonD,

Your response is greatly appreciated and should get me going. The hard plastic lines were confusing me especially since I don't know what their specs are and if there are readily available adapters to go between them and rubber, etc.

Anyhow, I will take your advice and do whatever it takes to make the repair.

My truck is about 3 hours from where I live so it may take a few weeks before I try something.

Thanks again for your thoughtful reply.

 

They make rubber vacuum lines just for these repairs, I mean small inside diameter so they can slide over the hard plastic and get a good seal, again this is Vacuum line, so a low negative pressure that PULLS connections together, which is why they don't need clamps, except for the larger one like power brakes and PCV, and thats more "safety" than "required"

If there is a wrecking yard between you and the truck then stop by and see if you can find similar vacuum ends, all car makers use the same type now, so not a Ford thing
Just cut the hard plastic line farther up, so you can put the "splice" inside the wire loom

The wire loom is a split loom, so remove the tape on the end of it and you can just pull it off far enough to work on that line
Looks like this: https://www.cabletiesandmore.com/ima...-wire-loom.jpg

When done you put tape just on the end so it doesn't split on its own

 

Good ideas thanks. I am familiar with wire looms so understand what you are saying there. FYI, this red line may be connected to power brakes as I know one of the two lines coming out of the loom goes there (different color) and bad brakes is a symptom I am having with the truck. I also think it originates from the vacuum reservoir. The spliced area is between firewall and engine unfortunately so that's going to be fun. Ha!

At this point I don't know what the vacuum end look like so that is another complicating factor. I wish I could find one of these vacuum repair lines you are talking about. I found a Dorman 1/8" connector but I don't know if it is small enough. I'll keep searching.

Very grateful, thanks!

 

You also have some wiring to repair, in your picture just left and up of your damaged vacuum line, I see a couple chewed up wires.

 

It won't be connected to Power brakes, for sure, that's just one larger rubber hose

Good eye, thanks for that. May have to take my USB borescope with me...
