DEF Pumps 'PIA's' Arggghhh!

Back in for my 3rd DEF pump. Second one didn't make it out of the Dealers lot before it failed however they wanted to wait for another batch. I guess they had done 5 on one truck a week earlier and all failed.

Really hurts performance as it de-tunes the engine turbo won't work etc. Emissions stuff are all of my issues so far. NOX sensors and DEF pumps. Only 48,000 miles too.

Fuel economy is still really good though if I keep my foot out of it. Still consistently 10-115% better than my 6.0 leaker. Back to what my 7.3 litres were.
