I’m with you, diesel is an oil, gas is a solvent. Diesel in itself should be lubricating the fuel pump, if it’s a lack of lubrication that is killing the pump then it’s a lack of fuel.How do additives reduce cavitation?
Per the previously posted diesel magazine article, cavitation is what is killing these pumps. I assume some were not being primed properly from the factory, and others were not primed properly after filter changes. I'm not confident additives address any of this.
Pump failures based on tremendous reading and research are caused by a mixture of the below.The OE calibrations for the EcoDiesel 2014 thru the present (both Gen2 and Gen3) all use this CPC mode as part of their calibration strategy. If you rev the engine while parked with the hood open, as the engine speed comes back to idle is very common to hear a prominent noise akin to gravel in a rock crusher or to an engine with solid lifter camshaft that has an incorrect valve lash. This noise happens as the metering unit flow is varied (via CPC algorithm) thru the pump and generally lasts for a number of seconds, sometimes going away and other times persisting indefinitely.
We surmise that during this transition period of flow rate that the noise is generated by a clearance that forms between the roller wheel and the pump’s camshaft. During normal operation (with the factory calibration), the pump operates in MPROP mode generally when under load but constant makes the transition to the CPC mode in light load and coasting situations. During that transition the MPROP has to make a large change in delivery almost instantaneously, leading to a loss of motion control within the valvetrain of the pump.
SorryIt’s inconceivable to think additives will extend the pumps life, no tune or snake oil will effect the longevity of the Bosch fuel pump.sorry for all the typo's above, I think I have fixed them all... :-P

Bunch of babies crying about nothing.
Yes additives are proven to reduce wear. There is zero argument to be made that that’s not true….
There is an argument to be made that wear isn’t the driving cause of this issue and thus additives will not reduce the likelihood of this failure mode.
Based on the failures I’ve seen, it’s possible the plunger is getting sticky in the cylinder and not returning to the lobe after lift. Then the piston turns, and the pump then self destructs
But saying additives do nothing is simply untrue.
I recommend looking for wear scar analysis with additives and without, lots of good reading to do there.
Yeah, either the piston sticks or it bounces off the lobe............and boom!Please send me and everyone the link for the comprehensive analysis you speak of.
You have no backing to your claims that additives reduce wear.
