1999 DODGE RAM 1500 LARGE EVAP LEAK P0443 P0455

- Just a quick video showing how I found a large evap system leak on a 1999 Dodge RAM 1500 v6 Magnum with error codes PO443 and PO455. (Not the Gas cap)
The Check Engine Light would turn on after a short drive after the owner had cleared the codes. The codes were not present when I did this repair because the battery had died right before he brought the truck to me.
The owner had also already replaced the gas cap.
I had carefully looked at each hose in the diagram shown in the video to make sure there were no splits or cracks and made sure that they were all connected.
You will see in the video where I found the leak just above the charcoal canister.
It wasn't necessary to take down the entire canister bracket/assembly, but it made it a lot easier to show/film the repair. I was unable to find the small 3-way rubber piece of that evap harness. I did find the entire harness listed, but it was shown as discontinued so I made it work with some 5/16" hoses and a plastic T fitting.

It's been a week since I fixed this, and the Check Engine Light has not come back. The owner just checked and there are no codes pending and all of the monitors and tests are complete. It is now ready for California Smog test.
Thanks for watching!

Best video I have seen it adressed exactly the problem I have and how to fix it . The dealer discontinued that part years ago so what he does is exactly what you have to do thanks😅
I recently ran into this same problem with the small rubber fitting but instead of replacing it with Tee fittings shown in the video I chose another remedy. Originally I was going to use RTV gasket sealer and recoat that fitting to reinforce it and make it stronger but didn't have any on hand so instead I chose to use some epoxy I have that was really thick with the viscosity of like wheel bearing grease. I mixed it up and then use a small paint brush to paint it around the fitting. I also glued the fitting to the canister. Overall this repair worked quite well for me. I cleaned the fitting with soap and water prior to the recoating so I had good adhesion. Just thought I would share my idea so others can chose which direction they want to fix this problem. This video was helpful.
What is it about Guys named Dan that just think sooo far “outside of the box”? I love it when people like Dan can adapt things like this that would leave so many others (like me) just crippled. Thank you for your brilliant video!!!
AWESOME VIDEO THANKS!! Im having same problem on my 98 DodgeRam 1500 5.9. I ordered same parts in your description. And added some 90 degree fittings so no possible kink in the hose.
Excellent video very well detailed and informative I’m having the same issue with my 01 Ram and it is the same part that is in the same condition causing the codes I will follow what you did to fix my issue thank you
Just unplug it by the filter
Trust me, we all appreciate this video
I just want to thank you again for this video. I just got been doing the same thing to my Ram 1500. I drove the truck about 15 MI so far and the check engine light hasn't come back on. Bro you are a lifesaver. Now on to our dashboards. My dashboard is like yours needs to be replaced. I want to wish you a Happy Thanksgiving as well.
Thank you so much! Happy Thanksgiving to you too!
Learn something new every day,thanks for this video,was a great help for my classic dodge.
Thanks for the video. I've got a 1999 Ram Van 1500...V-6 engine....I'm fighting the same issues for the calif SMOG test...that goofy angle rubber thing is rotten to the core...everything else on the whole system seems fine...only 2 electrical 'sensors/ components' in the whole SMOG system...Vapor 'Pump' and purge valve...I replaced both to no avail...the 'Canister is about the same as this one...under the drivers side...
I'm getting the 0455 code...I bought a smoke machine...connected it at the purge valve line...smoke comes out the larger line from the cannister at the larger 'Pump' line... so I guess it's working...pretty wimpy amount of smoke/pressure...no smoke seen at the purge canister despite the poor condition of that right angle rubber fitting.
Nothing going to the gas tank except one of those 1/4-5/16" hard plastic lines, goes to the right angle rubber thing....no pressure sensor ..just 4 wires for gas pump and gauge...
I'm a DIY'er...only got the crappy Haynes manual...little to no info on anything later than 1988...even though the Cover says...up to 2005...
Oh by the way. I did it your way. I didn't use Flex Seal. It only took about a half an hour to do
Awesome! Thank you very much
Great video
Thanks that was a wealth of knowledge. I have the same thing going on with my truck right now but I didn't know where to look. If that's the problem with my truck I'm going to get a can of Flex Seal and Flex Seal the crap out of it.
Mine has to have the same problem..... Advantage I have is my 2 parts trucks never had check engine lights for this problem..... Maybe that one piece is still useable on one of the other trucks I have. Still a better idea to put brand new hoses on it even if it's gotta be diy these days since they keep discontinuing parts.
Great video! hoping this will fix my truck. I have the same jar and sock contraption now I know where to hook it up. Love the tools you’re using too. What kind of flashlight are you using ?
Thank you,
That light is a Braun 390 Lumen LED Rechargeable Magnetic Slim Bar Work Light. I got it from Harbor Freight.
Hope this will fix your truck!
Take care,

Hello, watched video it was great, what's the name to that fitting that was falling apart? the one that connected the two into one. thanks
Thank you for watching! Unfortunately, I never found a name of the rubber piece that failed…
I think I found the same problem on my truck mine is a 1996 and it's on the driver side does that sound right?
evap purge solenoid circuit P0443. Replaced the solenoid. Preformed function test while plugged in it clicks/works. Checked evap connector has power. Solenoid works during test both oem and new aftermarket during function test. Preformed leak test can only see smoke coming out of the breather hose cap coming from canister. Is that normal for it to come out of the breather cap. 99 dodge 1500 5.9. Any suggestions would help me out a ton. Appreciate your time
I am not sure on that, but I would continue with the smoke testing and see if you have any other leaks down underneath near the canister. It was very hard to find the one that I had down there…
Best of luck to you. I hope you get it figured out. Please keep us posted.

I don't have my canisters on that brand. I got 97 second edition 1500 but I got a 5.9 mower I put in it can you bypass all that EVP stuff?
Your gas milage will get worse if you do.
I have a 01 Dakota with a P0442 and P0445 engine code. Investigation showed that there is a small tube going from the evap can to somewhere around the gas tank. At some point something hit the outlet on the evap can and broke it off. I've ordered a new evap can and the tube. Any insight on how to replace the tube to the gas tank? Thanks for your video.
I am not sure on the Dakota, but you might have to drop the tank down or put a camera up there to see where it connects and/or if it also had a nipple that broke off. There might be a video or diagram you can find online...
I recently fixed an evap issue with a jeep wrangler that had a cracked evap vent tube on the rollover valve (on top of the gas tank) with some epoxy and a vacuum fitting. Worked great. Here's a link to that video: ruclips.net/video/B8QqFEJeQG8/видео.html
Thanks for watching.
Thanks Dan, I appreciate it.@@DantheFixitMan
I had the same problem with my truck, but I used at end of a spark plug wire connector and a three way 1/4 plastic tee. my engine light has been off!
That sounds like a great solution as well!
Please please please send me information on the smoke machine that you built
Yes, please video how to for smoke machine
The link to the video on how to make it is in the description.

1998-2002 Mopar 53031130AC but I am not 100% sure on that. Best of luck to you!
Thanks for watching!

@@DantheFixitMan thanks for the fast response 💖
The hose was cut off I was getting no codes
What's that part called? I been trying to find it .... I just did a lil mickey mouse meanwhile
I never found the name of the small rubber part. I think it comes as a part of the larger hose assembly, but I believe it has been discontinued.
@@DantheFixitMan yes I've been told it's discontinued.
Was your truck running like shit? lack power? Load fluttering sound when trying to maintain a speed by chance??
No, this truck still ran ok, just had the check engine light on and those codes.
