Why use a tank sump for diesel pickup fuel system upgrades?

Powerstroke, Cummins, or Duramax diesel fuel tank sumps explained
A common upgrade for diesel pickup truck owners is a fuel system upgrade.  The stock fuel pump was only designed to supply enough volume to satisfy stock horsepower levels.  Owners of Ford Powerstroke, Chevy and GMC Duramax, and Dodge Cummins pickup trucks will find their fuel pressure dropping after making upgrades to increase horsepower.  Many owners will add a fuel system capable of supplying 100+ gallons per hour made by companies like FASS, Airdog, or Fuelab.  These systems are designed to supply a constant fuel flow and also add filtration to keep fuel clean.  One of the downfalls to these systems is the draw straw or factory suction pickup that is often used will not keep up to pump demand.  They not only make the pump work harder to suck the fuel from the tanks, but also sometimes prevent using all the capacity of the tank.  It is not uncommon to hear of a diesel pickup truck owner not being able to use the last 1/4 or 1/8 of tank of fuel with these sort of setups.

Those problems are the reason why Beans Diesel Performance designed their Fuel Tank Sump.  By installing a sump on the bottom of the tank, you are able to use 100% of the fuel tank.  Also, since the weight of the fuel in the tank is pushing the fuel towards the pump, the positive pressure actually helps the pump to last longer.  The pump will be able to supply an increased volume of fuel if it doesn't have to work as hard to get it from the tank.  Positive pressure from the tank sump also will help prevent drain back problems making engine starting quicker.

We often get questions about the durability of the sump on the bottom of the tank.  People sometimes worry that a rock or some other object will knock the sump from the bottom of the tank. Our good friend Ryan Bean (inventor of the Bean's Diesel Sump) put it to the test in this video.  As you can see there is no worry of the sump being ripped from the tank.

If you are wondering about installation, the tank does not have to be removed to install the sump.  The Bean's Diesel Performance Fuel Sump Kit includes a hole saw.  You simply drill a hole in the bottom of the tank and install the sump from the bottom.  Tighten the patented no leak design and you are ready to go.  The kit includes a 1/2 hose barb fitting which is compatible with most FASS, Airdog, and Fuelab diesel pickup fuel systems.
