surge tanks are mainly used as far as i know so that the motor doesnt lean out when the petrol tank is under 1/4 full.
they are usually put in either the boot, the engine bay or internal surge tanks (in petrol tank)
your best bet would probably be to get an internal one made. i dont think that you would get passed if in cargo bay as it is open into the compartment and if there are any leaks/explosions/etc then very hazardous.
the most common method for external ones near the tank is that they are filled from the top of the surge by a lift pump (small low pressure pump as small distance to travel) and then normal/high pressure pump feeds it to engine from bottom of tank.
if its in the engine bay then normal/high pressure pump to top of surge and lift pump to motor.
if you have an internal one then all is required is a normal/high pressure pump to motor as surge is filled within tank automatically.
with the return you can either have it go to the petrol tank or back to the surge. i believe if it goes back to surge it is a little better as less pumping/work required by lift pump.
hope this helps you.... also as for getting them made do a search in the sales sections as a few people on the forums make them if memory serves me right...
