Needing a little help...

[unknrbl]

So, I was working on getting the roof off of my truck and the air intake came loose from the truck. After putting it back on, I notice this tube was loose and this valve by itself. Dumb question, but does this tube go back onto the valve? If so, what is this a part of and how important is it? I've checked the 280 but can't seem to find anything on this. Thank you in advance and I do apologize for the picture quality.

EDIT: This is a M998 with the 6.2L, 3l80 trans.

That valve is a ford looking fuel filter acting as an air filter. the one end connect to a line that runs down the frame rail to the fuel tank. Its the vent line for the fuel tank. If you have the shallow water fording flush intake, that filter would be the end of the vent line.

If you have the deep water fording snorkel, like i suspect you do, that tube should attach to that vent filter and go to the straw looking tube clamped to the snorkel tube. That raises the fuel tank vent to the maximum height to match the deep intake and exhaust pipes

unknrbl, what model truck are you working on? It helps us to help you if we know.

Gotcha, thank you for the heads up. I only have the deep intake as the previous owner scraped the deep exhaust in favor for a traditional pipe. I'll get it attach asap, but would the truck be affected for daily driving use in the mean time?

one side of the little canister is normally open to the environment. The deep fording kit sticks a hose on the canister and runs it higher, as mentioned above.
There is a LOT more involved with the derp fording kit than just an exhaust and tall intake.

Thank you for the insight and I understand the system a bit better.
