Profile: Dieselcraft Fluid Engineering is mainly involved in diesel fuel purification and conditioning. We provide fuel test kits to detect biological contamination of all fuels. Our fuel stabilizers are easily installed between the tank and the primary fuel filter, have no moving parts and require no electrical connections. Our separator is based on surface tension principle and rotational fluid motion. We use a self-cleaning stripper screen to cause the water and solids to agglomerate and the vortex generator on exiting.
