I’m not sure that it ever had in the past. At the time of install the 150% was not a required test. The pump in there now wouldn’t have a relatively flat h vs q curve that is like to see in there for a fire pump. The issue now is would it be worth sinking money into the engine to push out more juice vs getting a properly sized pump, with a lower 150% capacity, which could be met without needing more power from the older engine. I’m thinking it may be worth a diesel engine tune up and retest with minimal hose lengths, kinks, etc before replacing the pump. Thoughts?
