Whether your blasting down the Quarter Mile, showing 'Who's Got The Power' or grindin' 6" canyons in the dirt, on the way to another Full Pull, your High Performance Diesel engine needs FUEL. The 'SuperDog 250' Fuel/Air Separation System delivers the fuel you need, when you need it!

The SuperDog 250, a result of 15 years of Fuel Preporator® research and development, is the most advanced Fuel/Air Separation Delivery System on the plant. Reliability and performance to produce the power to win and protect your fuel injectors, run after run!

For the Serious High Performance Diesel Enthusiast!

The SuperDog 250, a 'State of the Art', precision machined, die cast product, also includes an injection molded cover!

Three Big Reasons to Have A 'SuperDog 250' Air/Fuel Separation System On Your Diesel!

First: To make power, you need fuel. The SuperDog 250 delivers 250 GPH at a minimum 9 PSI.

Second: For your engine to make maximum power, correct injection timing is crucial! Air, entrained in the fuel, and vapor from pump cavitation, are compressible and delay the pressure build-up in the injector, retarding the injection timing. The SuperDog 250 maintains the proper pressure flow of fuel to your engine, preventing pump cavitation, and also separates the entrained air from the fuel, thus restoring correct injection timing.

Third: Air and vapor cause permanent damage to the injectors. When air/vapor, displaces the lubricating fuel between the barrel & plunger assembly, metal on metal contact causes galling. Pitting of the injector barrel takes place when bubbles, next to the wall, implode from the sudden pressure created by the down stroke of the plunger. Bits of metal are then knocked from the barrel wall. Finally, tip erosion, and the occasional loss of the injector tip. The result of air/vapor passing through the nozzles more quickly than fuel and the fuel then impacting the tip from the inside. The SuperDog 250 prevents vapor from pump cavitation and removes the entrained air, eliminating these problems.

You built the ride! You built the engine! PureFlow® Technologies built the SuperDog 250 to take you to the winners circle!
