FAQ
▔▔Q1: What does "fixed-displacement" mean for the Parker GP1 pump?
A: "Fixed-displacement" means that the pump moves a fixed, unchangeable volume of oil with every single turn of the internal gears. If you need more oil flow, you simply have to spin the pump faster by revving up the engine.
Q2: Can I use this pump if my engine turns counter-clockwise?
A: Yes, you can! The Parker GP1 pump is bi-directional (bi-rotational). This means it is designed to work perfectly whether your engine drive shaft turns clockwise or counter-clockwise. You do not need to buy a special model for different rotations.
