E-pump inlet pressure
E-pump inlet pressure
I've considered doing exactly this on my W463 G. The G's tank is fairly flat side to side. When the fuel is low you can run out of fuel when on a slope due to the fuel running to one side. I figure I could build in a small, but very tall tank under the hood (basically a vertical tube). Feed the tube-tank with a lift pump from the main tank. Have the engine take fuel from the bottom of the tube and return air/fuel back from the top of the tube. That way you can use all of the fuel in the main tank.
