    The $20 LB7 Injector Cup Tool

    OK, so I am a little lost with the pipe size and type. When I call around for a pipe material, the 1 1/4" pipe has an outside diameter of 1.669" and an interior of 1.375".

    Understanding LB7 Injector Failure

    Also, Does anyone recommend a supplier for new/reman injectors? Are there OEM/originals out there for sale? Or newer injectors that are updated? Thanks,

    Understanding LB7 Injector Failure

    RPM, That was our thoughts exactly. If it comes to it, we could do an LBZ swap (I had an '06 that was wrecked), and I loved it. Figure, I'd let my son make a project for a swap in his Diesel Tech program and get my moneys worth out of the tuition - LOL. Even inclusive of the cost of a swap, the...

    Understanding LB7 Injector Failure

    Thanks blk_smoke_lb7 for the advice. I will do some real world checking on the mileage. I do know on my ride up from Dallas to WY, I drove for 400 miles on a half a tank. That = 400/17 =23.5 mpg +/-, and that was at 75 MPH! That was real world calculations at the fuel stop!?. Anyway...

    I have been studying replacing my injectors on an '03 Duaramax. I would like to understand what and why the injectors go bad in these. So far I have read that dirty fuel, no lift pump, water, etc are the issues. Also, I have read that the HP fuel lines corrode and are a culprit. I would like to...
