The question is what size are the threads where the LPR goes into. I'm not sure if they're 2k spec.
Take a look at wevo's site:
Stock Class and Pump Paintball Headquarters - Wevo Paintball
Scroll down a bit and you'll see WGP pump kits for both 2k+ and Trilogy autocockers. Notice the pump guide rods are a bit different. Different length threads and o-ring placement.
I'd have to say that unless it's a Trilogy specific pump kit, it won't work.
