Anybody know what this (and leaking)?

[caldreamz]

Hi All,
I went out to continue work on my M1009 and found a puddle under the right rear leaf springs. It seems to be coming from this but with the spill mixed with rain I can't quite get a smell to tell what it is (or maybe I'm just congested)

Gotta be diesel.

Yeah, that's my thinking too. Maybe some sort of breather tube but why would it have a plug init with a funky hose clamp?

Does it trace back to the gas tank?

 

[caldreamz]

I haven't tracked that far back yet. The rain sort of killed my ambition and I didn't feel like putting on a full kit until I had more coffee

Vent for the rear differential?

The vents for the diffs are just hoses. That’s just a capped off fuel line. I suppose it could be a gas tank vent, but the fill tube is so big I wouldn’t think it would need one.

I belive it is a fuel drain.

TM 9-2320-289-20 on page 3-27 shows something similar and calls it a drain pipe.

I can believe the fuel drain (although I still think its a pretty sketchy way to cap the tube). It was a big leak and if it was differential the tube is above the differential which would indicate pressure to get it up and over and a lot of fluid loss. I'm still not sure why it would suddenly leak but I did recently top off the tank. I will trace it back on Sunday and hopefully answer the question.

Seems like a simple process to figure out your problem. Stick your finger where it's leaking and stick it to your nose. You will know right away if it's diesel.
