where does this hose go?
hello,
2003 suburban 2500 8.1 np 246 tcase While reinstalling the t-case noticed this hose hanging down passed the transmission. I don't remember seeing it while taking the tcase out. Its not the one that goes to the nipple on the t-case that one is on the other side and is shorter. Any idea where this connects to or is this some type of loose drain hose? pics to come |

Does that need to attach to somewhere or is it just for venting

Re: where does this hose go?
Could be a transmission vent.
The fuel tank vent is sometimes routed to a filter up near the transmission to cut down on dust ingestion. IIRC there's a TSB on this. That hose would be about the right size.
