Pressure Test of Intercooler ducting for P0299

Here is a pressure testing set-up I came up with to test the intercooler ducting to find a leak for the P0299 code.
I used my radiator tester and just got a 1-1/4' PVC plumbing cap, a 2" coupling and a 1-1/2" coupling from the local hardware store.
I could pressurize it to 10 psi.
Found a leak on the steel end fitting on the connector hose from the turbo down to the crossover tube.
It was worn through at the tab for the retaining spring clip.

Did you replace the leaking connector/hose with new or used? If new, how much?

If any of my AWM-style (funky-ended, expensive) intercooler hoses/hose ends fail, I'm considering converting (reverting) the whole works to an AEB-style set up with normal hose clamps...with an Apikol SMIC (for the MAP sensor) of course.

edit: Thanks for the data. Yeah for three bills, I'll definitely make that "AEB hose retrograde".
I replaced with new. It was $300.

The ATW and AUG also use the regular clamp on hoses.
it'd be nice if all their cars just used regular clamp hoses.... nope! had to get crafty on us! :(
