Motorsport Diesel Single Stage Relief Valve / Rail Plug Alternative New BOSCH rail pressure relief valve modified for single stage operation; not to be confused with rail plugs! This relief valve corrects common issues that plague the stock relief valve such as: rail pressure fluctuations and general drive-ability issues. The stock valve that comes from [...]

The new Motorsport Diesel Coolant Bypass kit, is efficient, compact and light weight. The flow control valve is now conveniently located into the riser. This new design will now clear virtually all turbocharger configurations. It will also work on 2nd gen and newer applications. Coolant pressures can exceed 90 psi in the rear of the [...]

Motorsport Diesel offers complete injector testing services. We use approved testing plans to determine the current state of the injector. We start with armature lift measurement, if that is within range we will then perform a baseline test. If it fails here we do not proceed further. If flow is within range we will then [...]

The 24 valve 5.9 and 6.7 engines have 11 steel press in freeze plugs beneath the valve cover. These press in plugs can be blown out due to a combustion leak from a head gasket failure. Engines equipped with a multi layer steel head gasket, can actually leak under high cylinder pressure and reseal themselves [...]

We offer common rail high pressure pump testing services. If you are replacing injectors, it is a good idea to also check the condition of the pump, after all it could possibly be the reason for injector failure. We test the pump for output at various rpm ranges, such as cranking speed, and wide open [...]

M12 x 1.5 to M14 x 1.5 threads. M12 x 1.5 end connects to the injector with a 60° inverted cone, or can be connected to a fuel rail. The other end is a M14 x 1.5 threads with a 60° inverted cone. Typically used for injector testing with flexible high pressure lines, or with [...]

M14 x 1.5 threaded cap to close port on rail, to eliminate injector connection to the common fuel rail.

We are the “OG Stroker Pump” producer from 2007 until today. We start with the best pumps to base our modifications upon, if it is not new, surplus new or a used pump that provides no less than 98% volumetric efficiency, then we do not use them to build Strokers. We now make our pump [...]
