Advice at 1 Million Miles

Just adding a final note:

Add "2885894: Cummins Decomposition Reactor" to the parts I've replaced. I think that's a first. They couldn't replace my leaking DEF doser without also replacing this.

Hit a big puddle of standing water near Detroit about a year ago. It tore a hose off the DEF doser and that's where that began.

Good news is that I'm out of the shop.

Thx again.
