NEW CUMMINS ADJUSTABLE OVERFLOW VALVE FOR THE BOSCH P7100 INJECTION PUMP ALL THE PROBLEMS WITH THE BOSCH OVERFLOW VALVE HAVE BEEN SOLVED!
  • ADJUST YOUR FUEL PRESSURE WITHOUT STRETCHING SPRINGS
  • BULLETPROOF DESIGN ELIMINATES HAMMERED SEATS
  • CURE FOR HARD STARTING AND LOW POWER
  • OFV010 USE WITH STOCK FUEL SYSTEMS AND DIESEL FUEL
  • LEAK PROOF CHECK VALVE PREVENTS BACK FLOW TO TANK
  • PRECISE FUEL PRESSURE FOR THE BOSCH P7100 INJECTION PUMP
  • VALVE IS PRESET AT FACTORY TO 30 TO 32 PSI
This is a direct replacement for the Cummins overflow valve.

PLEASE NOTE: THE OFV010, 020 AND 030 ARE NOT TO BE USED WITH A FASS OR AIR DOG PUMP. IF YOU RUN EITHER OF THESE PUMPS, USE THE HP OVERFLOW VALVES. THE NEW DESIGN VALVE WILL GIVE YOU MUCH BETTER FUEL PRESSURE AT FULL POWER.

Peak fuel flow on a stock system is 31 PSI. Fuel flow will fall off above 31 PSI. The Bosch P7100 lift pump is a pressure sensitive pump and pressures above 31 to 32 PSI will show less fuel flow. This has been verified with precise flow meters. Set your fuel pressure for 31 PSI for max fuel flow. Little known secret why lift pumps are failing The current Bosch over flow valve has a .105 inlet hole. The inlet hole size used to be .168 in diameter. The reason is, it protects the OEM seat and spring from damage. The small hole acts as an orifice snubber. Testing has shown that the hole diameter is too small !! The problem is, the small inlet hole has created huge pressure spikes in the fuel system and is wrecking lift pumps. The pressure spikes put a terrible load on the lift pump check valves. The Tork Tek valve features an inlet hole size that reduces pressure spikes by 39.7%. Your lift pump will last longer because it is not subjected to the higher pressure spikes of the Bosch design. A small but critical change to the inlet hole size has a direct relationship on the life of your lift pump. Bullet proof seat design Our goal was to produce a valve that has superior seat life. After many tests, we discovered that the number, size and location of the outlet holes were critical to the life of the ball and seat. We engineered the new design to put minimal stress on the seat. Less stress means longer seat life. You can now run your Cummins diesel knowing you have the best overflow valve on your Bosch P7100 injection pump. There is nothing worse than showing your buddy a new performance device on your truck and it's rusted. We don't black oxide any of our parts because it is not a rust resistant coating. Tork Tek plates all overflow valves in a two step process. The initial plating is coated with a second anti-corrosion sealant. Plating is a more expensive process, but it's worth it ! Your valve will look great and remain rust free for many years.

OFV010 Direct replacement for the Bosch overflow valve The OFV010 is for stock fuel systems that run on diesel fuel. Do not use this valve with WVO or biodiesel. These fuels will erode the ball and wreck the seal.

If you have a stock fuel system and run alternate fuels, order the OFV020. The OFV020 is built with stainless components and a Viton seal.

Included with the overflow valve are banjo seal washers and detailed instructions.
Installation is easy and takes only a few minutes.
