Maybe his lift pump was tits up and the dirtier filter from the cleansing of the bio was enough to kill the injector pump?
It really could have been some combination as such... but I personally lost alot of faith in Dodge engineering after the incident...
1. Lift pump failures are a joke to begin with... can they not figure out a better design after all this time. And if not, can they at least figure out a simple sensor to let you know your trashing your injector pump?
2. I've got a 10 year old Eureka vacuum that has better filter technology and engineering than OE Dodge filters. I can fully understand the crud from 3 years of reg. diesel lining the fuel system like cholesterol, but why is the Dodge filter not doing an adequate job. According to the dealer the injectors were plugged full of debris, how does it sneak past the filter?? Does it solidify AFTER the filter where its warmer? Doesn't make sense, crappy engineering IMHO.
Oh, and his OE filter wasn't that old at the time... it had been serviced at the dealership just a few weeks before his load of bio. I think bio is awesome... and overall it seems to work for most. Though a quick google search will pull up alot of less than satisfied customers. Does it sell more than the loud mouth of one truck that it trashes?? Likely?
