Back when these trucks were new and carrying big, heavy overhead hard side campers or anything heavy breaks like this were more common. I don’t think you see it as much any more because not many folks are as nutty as we are to take Squarebody trucks loaded with campers out on the trail.Holy cr@p, Larry! I've never seen this happen to one of these trucks before! Yours is one of my favorite threads on here and this is the last thing I would've expected on your rig! Looking forward to the repair process!

If you're still running a 6.2L diesel there isn't much you can do. If I recall correctly, the old non-computer controlled diesels just vented to the atmosphere. The EVAP I added operates exactly as it would on a 1996+ GM production vehicle where the ECM controls the engine mounted EVAP purge solenoid as well as the Vent Valve that is mounted on the rear passenger side of the frame. Those modules work together to burn off fumes when cruising while storing fumes in the canister when not running. EVAP is an emissions device manufacturers added for EPA compliance in the late 60s/ early 70s to capture the fumes/hydrocarbons and its one emissions device I actually love.Great job on this build and the repair.
Question about the evap setup. What is the plumbing diagram for setting that up? Looking to do something similar.
Thanks! There are always room for improvement when they're in surgery center ??Very nice work! I knew this would end up even cleaner and better than it already was.
Did all of the holes need to be welded shut and redrillled on the inner plate because of the resectioning?
Do you feel that your new evap set-up is superior to the TBI era canister?
Would a TBI eco run the later model can if needed?

EVAP definitely got better over the years as technology improved where the ECM took control. The EVAP operation of older carburated vehicles was pretty sucktastic at best that's why I removed mine years ago but adding the modern take on EVAP is totally worth it if you have a computer controlled engine. The down side is I will need to clean the throttle body much more often just like modern vehicles as the hydrocarbons coke up throttle bodies pretty bad over time
The issue with the aftermarket TBI would be if it controls the EVAP purge and vent solenoids. The factory setup will wait to purge fumes until you are at a part throttle cruise type scenario. I haven't researched the aftermarket systems enough to know if they can facilitate the EVAP functions or not.Swapping the 6.2 out for a Gen VI 7.4L BBC. Going to put an aftermarket TBI (stock type setup) sinceci didn't get any of the original EFI with the engine. Deal with gas fumes on my classic cars but would like to not deal with that on my camp rig.
