Year/Make/Model truck
2001 GMC EXT CAB 2500 HD

Engine code (LB7, LLY, LBZ, LMM)
LB7

Type of additional filtration added, and at what odometer reading
None Added

History of injector replacement, if any, and at what odometer reading(s)
182,000 KMS and the 2,4, and 6 injectors are still original injectors. The other 5 were done one at a time starting in 2002. The last one was changed 22 months ago. I've had no troubles since then. I use Stanadyne every tank full and I think it helps alot. The truck was built in Nov. of 2000 and went on the road Dec. 21, 2000. I am consistantly getting 21.5 mpg highway and 16 mpg towing the trailer (imperial gallons) .

Overall satisfaction with additional filtration - return on investment commentary
