How much pressure does a fuel injection pump have?

Pressure-Packed Fuel Injection. Today’s diesel fuel injection pumps are under pressure – even more pressure than what was once considered “normal.” Around 15-20 years ago, it was common for fuel injector pumps to process fuel in a system at around 10,000 to 15,000 psi (pounds per square inch).

What causes fuel injection pump to back up?

The spray tip (where the fuel leaves the injector and enters the combustion chamber) is particularly prone to “backing up,” so to speak. If your engine has ever sputtered or hesitated during acceleration, a clogged fuel spray tip might be the glitch. And it all starts with subpar diesel fuel.

Can a diesel fuel pump injector be clogged?

Diesel fuel pump injectors are high-precision components. They also deal with a tremendous amount of motion and other stresses. One small visitor inside (a piece of dust, debris, etc.) can clog the injector. Worse yet, a microscopic object can leave the injector open all the time. If the injector can’t close, cylinder performance is compromised.
