Sinister Diesel - Pressure Regulators

It’s critical that your diesel engine gets the right amount of fuel to produce the power you need. If pressure is too low, your injectors can outpace the fuel available and you’ll end up with nothing to burn in the cylinder.

Better Pressure, Better Performance

If you’re chasing a hard start issue on your Powerstroke, Cummins, or Duramax diesel truck, the cause could be a faulty IPR valve or fuel pressure regulator. Typically, the problems start when the engine is warm. Parts expand and cause pressure leaks which allows the diesel fuel pressure to drop while you end up with reduced power and poor running.
