Every Diesel Engine Needs Dieselcraft!

Simple installation
The unit is to be mounted between the fuel tank and the inlet side of the injector pump as close to the engine as possible. In most cases a simple splice into the fuel line or direct connect to the fuel filter can be achieved. All Dieselcraft units come with a universal mounting bracket and instructions.

It works as you run the engine.
No maintenance required
