Wonder how much more you folks would pay to NOT have this problem(s)
with the fuel pumps...that is a question they should also be asking...
Lets see. $8,400 diesel option added to $40,000 base truck with no frills. Sure whats more money, by 2020 we should hit 6 figures for diesel trucks.
There comes a point where the cost gets so high that the funds dry up to develop better products.
There is no cost advantage to owning a diesel for most people. You need to do some serious hauling, or haul for a lot of miles to even justify it.

I ran jet fuel in my '02 7.3 for years without problems. The difference between my 7.3, your Navy tow tractors, and current generation trucks is simply fuel pressure. Our older equipment was more tolerant of poor fuel simply due to the relatively low fuel pressure requirements of the engines. The lubricity is not as critical for lower fuel pressure pumps.
A few more differences than fuel pressure.
The 7.3 runs on HUEI. Fuel is supplied to the injectors under low pressure (4,000psi IIRC), a high pressure oil pump is then used to fire the injector (2?,???psi IIRC).
So yes your system runs at the high pressures of the CP3 common rail setups but off of a different concept.
