2020 Teryx 4 Fuel vent Mod Question

Hey guys, I've tried researching this here and the net with no definitive results. Does anyone know if the 2020 Teryx still needs the fuel vent mod? I know guys who have the canister under the driver seat say the don't, but I do not have the California emissions model, so is it something I need to do? Or is it primarily dependent on your driving locations?

Yes, I just did it on my 2020 it’s an easy mod, I didthe rear Diff vent as well. I drilled a hole just beside my rear driver side seat belt bracket and pushed the rear diff vent hose through and put a small filter on it.

Thanks I didn't see a canister under my drivers seat either on my new 2019 and was curious about the mod myself.

Fuel tank and vent are under passenger seat. Brute performance has instructions and pictures in their site.

Thank you for the response, I did see the Brute Force Kit so I'm going to order it. Thank you again.

New to the Teryx 4 family, what is the purpose of adding the vent tubes?

There have been issues with people having sediment in their fuel tanks with out much mileage on the rig.. one culprit is the tank vent line that vents into the frame... If you get into deep water, or ride exceptionally dusty roads, there is the potential to get water/dirt in your tank, causing your primary filter to clog.. extending the vent and adding a small air filter to it just lessens the odds.. the rear Diff vent is really poor, its maybe 10 inches above the diff.. so NOT so deep water and lots of dust will easily be able to contaminate your rear diff... another easy and cheap precautionary mod that can add longevity to the life of your rear diff. I'll try and take a picture of how I ran my rear diff vent when I get home today and post it up. I drilled a small hole next to my rear driver seat belt bracket and pushed the vent through, then added the filter, only way the rear diff is gonna get water in it now is if there is water in the back seat!
Hope this helps answer your question.. Its all about preventative measures and minimal cost.

A few pics for the rear diff. would definitely help, I bought the Brute Force kit, did the gas tank already, but I was a bit hesitant to do the rear diff as the pictures they use are close ups and make routing a bit confusing. I can see the vent line, just wasn't sure best way to route it.

TIA

Agreed, I didnt find their rear diff pictures helpful at all. Its hard to see, but you can follow the vent line up and feel where it bends and turns back downward, there is a plastic clamp that holds it in place. After looking around at the underside of the rig, you can see the "Y" shape in the plastic between the seats, this is the little storage tray between the rear seats, to the left of that was just wide open space, so I went up top, picked a "good" spot for a hole and started drilling. The hose comes through the hole and then tucks in behind the seat belt bracket.

Would love to see some pics.

I also have the 2020 and am trying to decide if I need to do this.

Honestly there's going to be two questions one is what kind of environment do you drive in the second is if you know if you have a model Trex with California emissions? Cause if you do the fuel vent mod is not necessary.

I just installed the Brute Performance kit last night, and they have you route the rear diff line through the gap for the bracket under the drivers side rear seat... so, get on the floor board and look at the front of the seat pedestal, where the metal bracket goes through the plastic and you will see a small gap. From the back tire you will pull the diff line from the frame and then follow that frame rail straight up (on the side closest to you) to the plastic. This is where your extension fitting will rest and the clear hose will go through that gap under the front of the seat. The filter goes on under the front of the seat (inside the cabin) and then the clear hose actually crosses and goes inside of the round rail that holds the door latch.
I agree the pictures were a bit hard to figure out, but once i realized it was the front of the seat, not underneath it, it made sense, and it is a pretty slick way to run the line inside of the metal rail.

Does anyone know the ID of the fuel vent hose and are all the vent lines the same size? TIA

I can't help with the ID of the hoses, although I would guess that the rear diff line is bigger than the others. But if you're looking to do all of the vent mods, I would consider the kit from Brute Performance. It's like $25 and comes with everything you need to do the fuel line, both diffs and the coolant line. It has an upgraded check valve for the fuel line, plus all 5 filters. I didn't price everything out separately but it was well worth the ease of getting the kit for me.

Thanks. I was hoping to use fuel line rather than kink-prone vinyl hose but I will consider the Brute kit. Is the vinyl hose in the kit relatively thick walled and resistant to kinking? Small equipment fuel filters like those are dirt cheap.

I can't give you a spec but it is pretty thick walled tubing, I had to use a heat gun to warm it up in order to get it over the barbs. yeah, i'm sure you could source all the parts individually for cheaper than the kit, but it was definitely an easy way to do it.

Thanks again. I just bought the T2 a few weeks ago and haven't even hit 20 hours yet due to cold, wet weather. I'll take a look at things when I do the 20 hour service and go from there. I'm guessing ~5/16" hose but will measure.
