Thanks for all the suggestions. Here is what I am dealing with. The fuel water seperator is a very obsolete one designed for the genny and the 8V92TA. It is mid coach nest to the fuel tanks. The engine bay has a primary and secondary fuel filter. Earlier today we applied posittive air pressure to the puel taks with a rag and reversed shop vac, Got little white and then a puff of black smoke, but no fire. Only did it for 30 second intervals. Then waited 10 minutes between tries. Didn't want to overheat the starter.
