[DeTomaso] efi fuel pump

[Paul Timko]

Generally an EFI fuel pump will have a pressure regulator set to around 
48psi.  The bleed off of fuel to keep the pressure at this point is 
returned to either the fuel tank or a special fuel surge tank.

It is possible for an EFI fuel system pump to either run continuously or 
it can also run occasionally.  It depends on the system, though I 
believe that most after-market EFI systems will run continuously.
