I have one in my fg xr6t sedan,I have the 1000hp in tank,1000cc kpm injectors,kpm modded reg and there e85 fuel filter.I think they work well,its whisper quiet.And came as part of a comprehensive kit with basically a plug and play wiring harness and detailed install instructions.Dave from KPM has always been very helpful when ive emailed or rang to ask questions.The KPM stuff is expensive,but it all fits like oem gear.Im at 441rwks on e85 at 18psi,and is doing it easy fuel wise.Joe from CMS recommended the pump setup.
