Big Problem with fat in IP!!

[arcticathlon]

This is not for my 300D, but for my friends Dodge 2500 Diesel Truck.

he got some oil from a restaurant hot, and filtered it hot through his oil filter that was inline with his pump. he then blended it and this all happening the same day added it to his tank while still hot.

it ran fine while it was hot that day, but the next day he died 3 times trying to get his truck home. replaced the filter once, and it was covered in yeloow/clear fat. the whole filter element was covered in a 1/16th inch layer of it.

SO.....

i came over and we first drained the tank. (it was yellow thick crap) then empied the fuel filter again (his 3rd) and filled it all with diesel. tank has 2 gallons in it, and the filter is full too. we then plugged the block heater in for about 4 hours until the engine was hot, and we also took heat guns and were heating the IP lines, the IP and the injector ends.

It would not start. we had to get my 300D next to it, and have it hooked up to a battery charger to keep cranking that IL6.

Still will not start. so is the IP soo full of fat that he has to take it out and clear out all the lines going to each of the cylinders? what better way to heat it. we might go and buy a pipe heater cable, and wrap it around the ip, but cranking it for over 2 hours and heating it has given not even 1 almost start situation. always just cranking over. i think it is dry, with his system i cant pump and bleed myself. it is all automatic with his system. we can hear and know that the fuel pump has diesel in it, but i dont think it is getting any of the diesel.

so i really just need more ideas of what we can do to get it started again. i know this is the wrong forum for this topic, but you are all diesel freaks.

he has learned his lesson. no filtering suggestions, he knows what he did wrong... now
