[Diy_efi] EFI lift pumps to swirl pot?

[Lee M. Lemoine]

I think one of the factors to be taken into consideration as well is
diameter of the hose.  I'm a fulltime firefighter, and we have to take that
into effect all the time.  Fuel will flow with much less resistance and at a
greater rate through a larger diameter hose with less friction loss than it
would through the stock fuel line...  How do you plan on regulating the
return pressure?  wouldn't that simply pressurize the swirl pot at 55 or so
PSI?
