Fuel (??) lines inside the cab B-pillars?

[XXL]

On the new cab I'm working on there are hard lines poking out of either side of the cab, just behind the door jam and just below the rear glass... I've taken many a seat tank out in my days and never ran across these before. I ASSume they are some kind of fuel lines. So, on to the question...

How on earth do you get them out? They seem to be permanently affixed between the inner and outer sheet metal of the cab.

Any ideas?

71 was first year of emissions including fuiel tank vent fumes recovery system, those lines are not for raw fuel they are for the vapors and a line runs up to to the charcoal canister in front corner opf truck under hood to capture them to be sucked into carb base upon fire up of engine,
caps on 71-up are different from earlier caps

Thanks for the additional info... actually I realized they were _vapor_ lines and not liquid fuel... but my question is how to get them out so I can throw them in the trash. Any suggestions on that?

Thanks,
