FAQ
What horsepower range does 165GPH support on the 6.6L Duramax?Generally ~600–1000 HP when the rest of the fuel system and tuning are matched.
Which filters should I run?
Use the current pair: XWS3002 (pressure side) and PF3001 (suction side). Extended-length setups use XWS-3002-XL and PF3001XL.
Do I need a sump or suction tube?
The No-Drop kits include a sump; otherwise the STK1002 Suction Tube Kit is a popular add-on.
Is this a complete replacement system?
