Any A&Ps here have experience digging for leaks in the fuel shroud under the pax cabin floor on the CRJ-200? I had to track down a fuel leak for the APU feed line today. All I can say is I hate Mr. Wiggens and his damned clamps
Yes. That set up with the APU fuel shroud is a lousy set up. I see you have had fun taking everything up in the cargo bay and disconnecting clamps to find where the leak is. The best is when you have the shroud open and have some one power up the APU fuel pump and SPRAY every where !! I am NOT a fan of the CRJ 200.
Result: Fixed leak. Ours was @ where the fuel line went into the APU itself. It then leaked fuel in the shroud all the way down. As for the spray, we got it cleaned up so the family didn't complain about the smell on the bags.
