I recently had my husband replace my vapor canister as that was the only thing that hadn't been replaced to fix my emission error lights. Now when my husband replaced it, he said that some of the hoses look like they are starting to split. So I need to order the hoses but I am not sure which hoses and neither does he, there are three I know of the one to the fuel, but not the others. When he replaced the canister the check engine light was still on and reading the same codes. Everything that involves the emission system has been replaced except the hoses to the vapor canister. Any idea what it could be if we replace the hoses and it stays on?

 

Welcome to DF!

2004 is actually the last year of the 2nd Gen Dakota. I will move you there.

 

Hi and Welcome!

What engine, tranny, and codes do you have?

 

You may find what you what from AutoZone or one of the others they have generic fittings elbows and so on that should work.

Just make sure they can take gas and gas fumes or they will rot ASAP

Rated for use with gas/fuel

 

And there is one fitted/formed hose that is for 2 different size fittings in a horseshoe shape, you have to get creative to replicate it...

 

This is out of the 2003 FS manual

 

I just replaced all of the junk on my ’04 and my check engine codes are all gone.

I found the hose from the Leak Detection Pump - it kind of looks like a question mark. My part number was 52102801AD.

I didn’t replace the smaller center hose - it looked OK to me.

The hose to my gas tank had a small crack, and according the parts place the hose isn’t available anymore and they suggested just buying a hose and elbows to replace it. I decided to try “fixing” the hose and if that didn’t work get new hose pieces.

For all of the connections on the new canister I rubbed the inside of the hose ends with silicon lubricant that I use on rubber parts for my pool (Magic Lube II) and installed a clamp to keep the hose sealed in place. I also put the silicon lube and clamp on the other end of the new hose that connects to the pump. On the hose to the gas tank I cut off the small crack before putting on the lube and clamp.
