question about a returnless fuel rail setup

[farmerz24]

hey, here is my question:

do you think that instead of a conventional sfi or mpfi regulator that ultilizes a return line i can basically have a line coming from my tank that goes to a regulator mounted to my firewall, then before the regulator Y off of this line which would then go to the fuel rail, and terminate (no return from the fuel rail). the return would be on the regulator itself on the firewall and be sent back to the tank this way?

is this possible? I mean the fuel rail should still see full pressure as it must pressurize this before the regulator lets fuel back through the return line.

the advantage is that i only then need to run 1 line to my fuel rail and would be less clutter. what do you guys say?

thanks

Looks like it could work.

The only thing you might want to think about is the heat generated. One of the benefits of having a return to the tank is the cooling that you get. The fuel pump and fuel stay cooler. Hence better performance.

having a returnless rail also allows the fuel in the rail to heat up more as its sitting in the rail for longer before its consumed. however, the new ls7 in the vette uses a regulator near the tank and runs one fuel line to the rails.

i personaly will stick with a returning fuel rail.

there is a major plus in running a returnless fuel system, the hotter the fuel gets the fatser it will vaporize, you just have to keep pressure on it to keep from getting vapor locked.
