I tried that once before and it still threw a code, and the check engine light came on. This is the hose with two, different sized fittings.

 

Dodge had some weird ideas on hose sizes or it was a way to get you to only buy a part directly from them. I wanted to get a replacement PVC vacuum hose for my Dakota and nothing fit correct so I ended up putting the original hose back on.

What year and engine so on is you’re Dakota I will try and find the hose for you if you look hard I think an OEM inline will have the hoses?

Never lose your original PVC or vacuum hoses as SOME but not all are a very off size

 

It's a 2003, 4.7L, extended cab, 4x4. Thanks for your help, man!

 

So its the hose you need?

This is what I found # 2 in the diagram the pic is generic but always call and be sure thats it from them

When I had to replace some emissions hoses under the hood on my truck, I had the same problem, one hose had one size hole at one end and a different size hole at the other end. I went to the parts store and went over to the emissions parts area near the air filters and picked up a pack of assorted tee adapters and straight hose adapters. Then I just bought the 2 different size hoses and made up my own hose with the tee fitting, taped it all up solid and it has been working fine ever since. Much easier and cheaper than buying at the dealer.

Yea I have done the same thing grabbed a bunch of different fittings from AutoZone or it was O-Riley and came up with something that works I even used a tie wrap like a hose clamp on one that just was a little too lose on me

If you are good at that you can get a working fix/work around but the hose on that web wasn’t all too costly $10 and ad shipping so maybe $20 just order a few things and make the shipping stretch out for you.

I’m not sure what hose he needs?

You can always get a hose that fits the small fitting and just cram the other end onto the larger side fitting lube up the hose a bit and some muscle

 

Be careful what hose you buy for replacing any vacuum hoses/lines it needs to not expand with heat. Make sure its made for use as a vacuum hose/line just like you need to be sure of any automotive hose you need. Any hose in your auto needs to meet certain specs for use like will it work for gas or brake fluid what chemicals will the hose meet/withstand and not decompose/rot or swell up or maybe even shrink

A good article on this LINK

 

Yeah, see, that's part of the problem with what happened last time. The auto parts strore doesn't stock vaccum lines that large, so I had to substitute for fuel lining. It didn't work...

I've tried "rigging" this problem before and it didn't work; that's kinda why I just want to get the OEM part.
