I´ve heard from some people that they pressurize their fuel rail from both sides. I´m wondering what are the advantages oder disadvantiges of this setup. And I´m also interested in how it looks like and how it works. Where are the lines are connected to. Any ideas????

If you measure egt's after going to a dual feed rail they seem to be more consitant across the board. Better power balance and now you aren't tuning for the leanest cylinder rendering the other 3 a little richer than desired. 4 cylinders working together better= more hp.

Thanx!

Some more ideas?

I know that a lot of the 6 cylinder guys do this... I think I'm going to do it on my setup... I don't see any way it can hurt. Bump for more info

Since fuel is a liquid the pressure will be equal across the entire fuel rail as long as cavitation does not occur. (Fuel injectors do not pump fuel) I think the real point is to provide more flow for higher consumption requirements.

And where do I connect the return line to? Isn´t here anybody with a setup like this who can show me some pics???

Yeah thats what Im asking too. Would dual fuel inputs eliminate the fuel return?

Some cars' fuel system are returnless (RSX) but this would be redesigning the fuel system.

These seems interesting !

Bump for more information and maybe some pictures !

The return will be taken out of the middle of the rail or back at the remote mounted regulator.

The fuel goes in the upper rail, fills it and then goes to the second rail and then out of the second rail to the return with no problems. As long as you use a pump with enough volume, it doesn't matter where the fuel comes from.
