Which P pump is the best?
The general consensus is the 180 hp pump is the best of the P-Pumps for high hp goals. The 160 and 175hp pumps can not move as much fuel as easily as the 180 or 215 pumps. When you start looking at school bus and other applications of injection pumps knowledge goes downhill on what to do with them for upgrades.
What is a 12 valve P pump?
Driven by the engine’s cam gear, the P-Pump is an injection pump that gets fed fuel from the lift pump (which takes fuel from the tank). The injection pump’s six plungers—which ride on a camshaft in the pump housing—move up and down in barrels.
Do P Pumps go bad?
Premium Member. Everything mechanical eventually wears out but the P pump goes a long way. They usually start out by missing when they get old. About the same price to trade your core in for a pump that’s already rebuilt as it is to have your own rebuilt.
Whats better VE pump or P pump?
The P-pump would be the best choice for an all out performance build. The VE pump is a single piston pump and is limited on what you can get out of it. Basically, every cylinder is fired from one source. The P7100 has a piston for every cylinder with a cam setup basically like the valve train on most engines.
What is a 13mm P-pump?
These pumps are typically build to order. 13mm pumps are competition pumps and are prone to stalling, over fueling and must be fed by a large lift pump like Fass or Airdog 200GPH. Lack of fuel supply to the pump can seize the plunger.
What year Cummins has the P-pump?
Believe it or not, the P-pump was introduced so the 5.9L could meet 1994 emission standards set to take effect on January 1, 1994. The higher injection pressures produced by the P7100 were used to cut down on particulate matter produced in-cylinder (and exiting out the tailpipe).
How does P-pump work?
The function of a P-pump is relatively simple, although it may take a few readings to understand. The pump basically acts like a small engine, but instead of compressing air, the rotating plungers compress fuel to thousands of pounds per square inch needed for diesel injection.
What year did Cummins have the P-pump?

Is a VE pump reliable?
