fuel pumps

I will also be converting to EFI shortly and wonder if the following will 
work:

Use a low pressure electric pump mounted by the tank feeding forward to an 
insulated fuel resovoir ( say 1 liter in size) mounted in the engine 
compartment equipped with a float to keep the level constant. Then feed the 
high pressure pump locally from the bottom of the resovoir and route the 
regulator bypass outlet back to the top of the resovoir. The only problem 
that I can see is possibly vapour being trapped at the top of the tank.

Best performance will be gained by mounting the pump low and as close to 
the
gas tank as possible, making the low pressure (inlet) flow circuit short.
Most pumps don't do well with suction, but are happy pushing all the gas
they can get.
