19th Jan - Fuel system?

Following on from the weekend and the IP return air problems a few ideas have come up.

  • A) From 'SimonR' on LR4x4 was the idea of fitting a 'swirl pot'. This would receive both the return fluid and the supply fluid from the tank via a LP pump. The schematic idea below ,while not exactly the same, gives a good idea how such a system would work. Cost here is the pot plus an LP pump - so say around £100?




  • B) Modify the military manual changeover/tank selector valve to dual gang. i.e. fit another 3 port valve behind it to direct the return back to the correct tank (my preferred option if doable).


  • C) A set-up as in the schematic below. No parts cost but the balance/overflow would have to be big enough to cope with the possible situation if the main tank became full (such as during extended idle). the only parts needs are the return pipework to the main tank and the balance/vent pipe between the two.
