Hello, I have an AEM fuel rail having the possibility to mount fuel feeds from either end. Why not feed both ways? There are dual carb feeds?
If the rail feeds the injectors in series then doesn't the farthest injector get reduced production - like a string of lightbulbs??
Does the oversized AEM fuel rail and adjustable pressure regulator overcome this "series" effect?
Am I a nut to entertain a dual feed rail? OK. but it sounds...yaano? Thanks.

 

Hey,
One fitting should be fine...
Lemme explain the similiarities between electrical circuits and fluid mechanic systems...
In an electrical circuit, u have current and voltage; Voltage is analagous to Pressure and Current is analagous to Flow Rate...
U can have 5 volts, but alot of current, as well as having 5psi, but alot of airflow (like a big turbo)
Or u can have 50,000 volts and very small current, as well as having 15psi, but only moving a little bit of air...
Get it?
So, initially the idea about the fuel rail feeding the injectors in a SERIES configuration, was wrong, because the injectors are actually in a PARALLEL configuration...
when your fuel rail is pressurized, and all of the injectors are located in the same volume, all of your injectors recieve the SAME pressure and hence the same flow through the injectors, no matter if it's cylinder 1 or 4.
because the injectors are SHARING the same source, ie the open fuel rail, they all get the same pressure.
Hope this helps
Later

 

thanks!! I bees whatcha knowins!
I am going to set my secondary runner pressure pot set screw to wide-open!!!!
Now I can go get (1) SS fuel feed and feel goodabowdit. Well, until I start messing with the fittings and tapers and banjos - OH MY!!!!!!!!
