Got the EOC Stage 1 tune installed. Need to drain the DEF, but no idea how. A siphon tube down the filler hole does not work. Anyone know the best way to drain the DEF?.

Is the DEF tank behind the gas tank? Everything is covered in skid plates, so I can't see it.

Any advice appreciated.
thanks

If you follow the DEF filler hose down to the DEF tank, then you should be able to disconnect the hose where it connects to the tank. From there, it's easy to siphon the DEF out.

If you find a drain plug let me know. Waiting on my down pipe from them and then I’m going stage 2

Have you done this? I can't follow it down with the skids on. Is the DEF tank behind the fuel tank?

I removed the fill hose on my 2015 EcoDiesel and siphoned the DEF out. You will need to remove the skid plate to gain access. I have not done it on the Gladiator, though.

Remove skid plate from def tank. Then remove the 3 screws holding the pump in. Remove pump and let drain. will take about an hour to drain completely. Easy peasy.
AWESOME! That's what I was looking for. Thank you for the reply!! :clap:

Are you going to do the pipe that goes from the down pipe then reconnects to the existing exhaust flange just in front of the rear axle? Does the one you ordered have a resonator? I want to get a new exhaust that sounds good but I don’t want it to be so loud I get unwanted attention. Its tough to choose without ever hearing one.

Yeah I won’t have a resonator but I’m still using the stock exhaust. Once it’s all done I can make a video, I agree I wouldn’t want to do a straight pipe but I want a bit of noise

Nice! Are you gonna do the multi map or the one tune. I can’t decide on that either

I have adaptive cruise so I can only do the single tune. I think I’m going to go with the street tune. The race tune just seems like it’s going to burn up the transmission
