wvo svo heat exchanger fuel tank

  1. Heat exchanger and fuel tank

    Heat exchanger and fuel tank

    Here is another shot of the heat exchangers in front of the tank. NOTE: I needed to add a 90o elbow before the hose barb due to clearance issues - otherwise the coolant hoses kinked when I installed the tank.
  2. Coolant fittings

    Coolant fittings

    This pic shows the top and bottom halves of the coolant connections to the fuel tank. The brass barb connection screws into the lower brass tee connection that has the copper elbows on it. I will use Teflon tape on the threads and a rubber grommet and plumbers putty on the washer to control leakage.
  3. 5/8" hose barb connectors

    5/8" hose barb connectors

    These are the 5/8" barb connectors for my coolant hoses. I had to drill two 7/8" holes in the tank for these fittings. NOTE: I needed to add a 90o elbow before the hose barb due to clearance issues - otherwise the coolant hoses kinked when I installed the tank.
  4. Forward heat exchanger

    Forward heat exchanger

    This is the forward heat exchanger. I used 1/2" copper pipe and 10' of copper strapping for added thermal conductivity. The fuel pickup nozzle (sitting on the tank) just fits beside the heat exchanger. I think the fuel level sensor float (little yellow cylinder) may be stopped by the heat excha
  5. Aft heat exchanger

    Aft heat exchanger

    Here is the aft heat exchanger, close up. I used 1/2" copper water pipe and soldered on 10' of copper tie strapping for added thermal conductivity. This assembly had to be small enough to get in the fuel tank access hole, about 4" in diameter.

    Here are my 1/2" copper heat exchangers for my fuel tank.
