Fuel Pump: ref McKenzie
 
If your're running a mild or some degree there of, engine, a 3/8"
pressure line, and a 5/16" return line should work, fine.
  In order to save a bunch of work I'd rerig things remembering the
return may have some pressure in it, and rerig the pressure since it will
have alot more.  Mock the engine together, wiring etc.., and run a 
pressure guage in the return line.  If you have more than a couple PSI,
then replace the return with one size larger, if 1/4" then 5/16" and the
like, assuming you have not somehow run the return line below the fuel
level in the tank.  Be sure the line is above the fuel when full!.  
IMHO, Bruce
