Review on 🏎️ Melling High Volume Oil Pump - M99HVS: Optimized for Superior Performance by Harald Patterson

Revainrating 1 out of 5

Excellent pump for crank and bearing destruction

The first pump came without pickup and drive shaft. On my second pump, an oil pressure bypass valve was open resulting in zero oil pressure and killing the new rotating assembly. This pump is garbage

Pros
  • Best in its niche
Cons
  • Bad impression
