For years I searched for such a piece.  It is superior to hose in hose or coil in coil designs because of 3 things:

The king of veggie filters! Use with our 12v gear pump and stainless or electric heat exchanger for a complete filtration and fueling station.HUGE pleated filter element has the same surface area of a large filter bag.

This is a general fee that I charge for consulting.  I can give you advice on any kind of technology.  I specialized in internal combustion engines, biofuels, emissions, computers and websites.

 

This beautiful bus will surely be bought quickly. A coach of this caliber usually goes for 35-100k. It took U.S. and Canadian coaches about a decade to catch up to what VanHool was doing in 1989.. This means this coach looks nicer than late 90's american and canadian coaches costing 80k.

The only way to go, even on the bullet proof Mercedes fuel pump, is a real two tank conversion.

Same as RE-CP1 but with 24 Volt motor for tour coaches and big rigs.

The holy grail of collection pumps.
  Durable corrosion free aluminum gears.
  Reversible mode allows you to back flush the stainless steel strainer filter.. which means you can run a finer strainer and make your dirty filter last longer.
  When the strainer clogs just reverse the pump to backflush and continue collecting.. huge time saver!
  Industrial model available for longer duty cycles.

Same as RE-GP1 but with larger more industrial motor for longer duty cycles.  Useful on large tanks when filtering 100's of gallons at a time. The perfect match in flow rate and durability for the racor fh1000 3gpm=180gph
  This burly pump is available with a heavy duty motor for longer duty cycles as well.

The perfect match in flow rate and durability for the racor fh1000 3gpm=180gph. This burly pump is available with a heavy duty motor for longer duty cycles as well. Solid brass gears just last and last. There is even a rebuild kit available if you somehow manage to blow a seal. Dont waste your time on cheap pumps with plastic fins.(hint any pump under $200 will fail quickly)
