Where did you get your A1000?
So far the raptor pump($359) and the marine grade Aeromotive pump($432) are the only pumps that carry a diesel warranty.
The other options are the Bosch 044($200+) and the Walbro GSL392($100-$120). I and a few others run the Walbro and they handle my B codes injectors just fine. The walbro maintains 62psi under any condition I can throw at it.
