VP Monster Pump Internals
 

I see II is now claiming to have the closest to new remaned pumps , I was under the impression that 50% of vp44 failures was the rubber seals and every remaned vp44 them seals are replaced with brass seals ,

How many parts are new / upgraded for longevity on the Monster Pump?

The monster vp is the stock electronics but WAY different hardware on the inside. The only thing i know of is there is a custom cam inside the monster that Mike builds himself for each pump he makes. Coaltrain is Pretty educated on these pumps Or get a hold of the builder Himself to answer you questions better.

Unfortunately most vp failures are electronic.
