we have a d3 gxl...
we have a d3 gxl 2003 cat dozer, we changed fuel filters then started getting low power, we experienced similar issue on skidder, the vaunted deisel problem of slime was its cause, however dozer acts differrently, we changed filter twice to get work done dozer will run approx. four hours but missing occasionally, then completely quits, i assumed it was fuel system needing cleaned but cant shake the feeling it is something else like a screen i keep hearing about in forums, located somewhere near the transfer pump, last time we changed filter it only was half full, do i have to go through whole system and where can i get detailed diagrams to help me in my endeavor, i was an aviation eletrician in USMC, i can do anything with right diagrams and tools, thanks in advance

well not yet, but we took all the lines loose and cleaned them plus screen by transfer pump, tank was horrible with sediment on bottom of tank, appeared to be plugging the pick up line, , put it all back together and it still does smae thing, so either we have a line collapsing or we missed something somewhere, i have never seen that much rust floating in tank and lines were horrible until after main filter they seemed fine, the one thing im having trouble is when looking at certain parts i also need to be able to disassemble them to clean, for example the water seperating filter housing , i need better diagrams and just nothing good yet, thanks

if it was that bad, I suspect you may have junk in the inj pump itself

Yes it will get past the filter
