The diesel fuel injection system is the heart & brains of a diesel engine.  Today's diesel fuel & biodiesel can often be damaging on the fuel injection system due to water in the fuel, lack of lubrication which causes metal on metal wear of the parts within the injection system, or off-spec biodiesel that can cause the fuel system to badly gum up  with fall out products of the biodiesel, etc.   As the diesel engine technology advances into the electronic age, tolerances are extremely  tight, and contaminated fuel is not tolerated.  Damage to the fuel injectors or injection pump due to any kind of fuel contamination can be extremely costly repairs.  Fuel contamination and subsequent damage is NOT covered by any manufacturers under warranty, therefore it is vital that YOU as the end user takes measures to ensure that your diesel fuel is treated with PROPER fuel additives to protect your investments.

As we rebuild fuel injection systems, we see first hand what damages are caused by poor quality fuels.  In 1976 we became a distributor for FPPF Chemical Company because we had to find a way to help our customers prevent such unnecessary and costly repairs.  TODAY, we are one of the largest FPPF distributors in the nation.  We sell FPPF because IT WORKS!  We are continuously testing and comparing FPPF products against the numerous brands of fuel additives on the market.  All we can say is  GRAB THE BEST -- GRAB FPPF .  We are here to troubleshoot all your fuel needs, including bulk fuel storage tanks.
