Genuine Donaldson P550848 Fuel Filter Water Separator | Cummins QSC QSL Tier 3

Genuine Donaldson P550848 Fuel Filter Water Separator

Genuine Donaldson, printed Fuel Filter Water Separator in four languages, P550848, with the Donaldson Twist and Drain head fitted. Made in Mexico by Donaldson. The unit in the photo is the complete spin on with its drain valve.

Water is the quiet killer in a diesel fuel system. It does not just rust the tank, it flashes to steam at the injector tip and it destroys the lubricating film a high pressure pump depends on. A separator like this coalesces the water out of the fuel and holds it in the bowl until you drain it, which is why the Twist and Drain fitting exists: you can dump the bowl by hand without tools and without cracking a line.

Catalogued application
