Sinister Diesel - Pressure Regulators for Duramax

It’s critical that your Duramax diesel 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 fueling issue on your Chevy or GMC Duramax, Sinister has the parts you need. Typically when fueling components fail, you’ll notice hard starting and poor running when the engine is warm. The pressure leaks that result allow the diesel fuel pressure to drop while you end up with reduced power or misfires which can even damage your engine.
