Fuel issue solved

Hi all.
I wanted to post the fuel issue I was having by gas not getting to the carb on the 454 motor.
After driving the motorhome for 15 minutes or so fuel stopped getting to the carb.
After checking the fuel pump, fuel filters, and pretty much all hoses and lines I decided to blow air through the fuel systems for both the main and aux tanks/lines.
I started with the vaper return line from the aux charcoal canister.
I disconnected the hose from the canister to the hard line. Blew air through the hard line and it seemed the air was free flowing so I figured that wasn't the issue.
I got a wild hair at that point and decided to test the charcoal canisters and found that both were plugged and not allowing the return vaper line to breath and causing vaper lock.
I left the vaper return line disconnected and went driving around to include one of the mountain passes up hill.
I didn't have any issue.
So.....check your canisters and lines.
Your problem may be just that simple.

Thank you.
I should have posted how I blew out the system as well.
A very contoled release of air, only enough to hear (by a second set of ears from my buddy) air in the tanks or blow out the system.
I added air gun and hose to my portable air tank.
