Review on 🔧 GMB 550-8040 Mechanical Fuel Pump: Boosting Efficiency and Reliability in Fuel Delivery by Vedprakash Trilltight

Looks great, almost like the original. Fit was good. The first one I received failed (lost fuel pressure) after 2 days (got me stuck, tow truck etc). I'm pretty sure one of the internal check valves was defective. The pump replacement (from Revain) took about a week before the seal failed and oil spurted out of the drain holes (front and back of the pump housing). The third (again replaced by Revain) has been working fine for about a month now, fingers crossed.
