diesel, if my d e f pressure is fine and it's showing low nox conversion that goes away, after a regen, could it be that my d e f inlet filter as shown here is needing replacement because I'm getting poor d e f quality signal 3364 fmi 2?
In the video, I don't show a lot of it, but I'm installing an "RS Supply Kit". It also consists of a DEF Filter, DEF Pump inlet fitting/screen and DEF Pump Pressure relief valve/Plug. I believe the part number for it is A0001408678. If you just want what you need to change the Doser inlet screen, the part number should be A0001401494. As always though, I'd recommend contacting a Detroit parts dealer with your VIN/ESN to make sure you're getting exactly what you need.
You did not show the mounting gasket proper installation orientation. The new gasket has 4 small protrusions sticking out on the same side as the gold lettering which is shown facing up in your video. The old gasket e help!either one, so I'm not sure how to install the gasket properly. Please help!
+Bad Guy A DEF quantity test is most often used to see how well a Dosing unit is performing. During the test it needs to inject a specific measured amount of DEF or it fails.
Yall may call me a liar but I once saw a (mechanic) take the doser off to install a new one that is not the issue what he did next surprise me...he took a funnel and started putting hot water trough the doser hole on the one box then ran the engine after he finish I ask what was the water for....he said to clean and devolve the def build up....I don't believe it
The lines are basically siphoning DEF out of the tank. New DEF lines come with plastic plugs installed in them to keep debris out. I usually keep a few different sizes on hand to plug lines while I have components removed. You can also disconnect the suction line from the DEF tank to stop the siphon.
TheDieseler it isn’t obvious to someone who is just learning the names and part locations of the system. Some don’t know the difference between EPA07/10 or GHG14. How would a new Owen operator, like me, know that GHG14 is airless if he owns a 13 cascadia? So he’d be watching this video and would be looking at unfamiliar parts. Now if you titled DEF injector first GHG14 or put the year in the title, it would bring clarity to someone who don’t know as much as you do.

What is the part number for the kit? My inlet screen has a hole in it
where can i get the gasket kit
I thought my truck had this but it has a metering unit. Do you have any tips for cleaning a metering unit on a later model truck?
+letsgo243 I don't work on metering units much anymore but I'm trying to get something together.
Thank you
Do you have part numbers for the service kit?

And approximate cost?
How would you know that dosing unit bad and needs repair?

Were can I get the kit

How the hell do you stop the flow of Def after you disconnect those lines?
The lines are basically siphoning DEF out of the tank. New DEF lines come with plastic plugs installed in them to keep debris out. I usually keep a few different sizes on hand to plug lines while I have components removed. You can also disconnect the suction line from the DEF tank to stop the siphon.
@TheDieseler I was thinking about that, but haven't disconnected from the tank yet. Thanks
Please say what year and engine in your videos for clarity. Thank you. Not all are the same.
This video is on the airless dosing unit so it obviously began with GHG14 engines. It has not seen any real changes since then.

I do not find my dosing unit in the one box.
