Fuel Rail Idea, Do You Like?

[blageo23]

Im not going to take credit for this because I saw one for sale on ebay but need to know if it makes sense.
Here is the basic idea. Our cars have a problem with cylinder #1 not getting enough fuel(less then the others). So I thought this would work but Im not an expert like some of you guys.

Take your stock fuel rail and drill a whole in the center of the fuel rail(inbetween injectors 2 and 3) and you make that where the return line goes. Then you make both sides of your fuel rail inlets. So have fuel inlet on both sides of the rail and the return in the middle.

Does that make any sense to you guys? would this give you optimal fuel or would the fuel get all F'd up in the middle of the rail?

#2 is actually the cylinder that runs the leanest generally.

#2 is actually the cylinder that runs the leanest generally.I thought that was due to air distribution, not fuel?

I thought that was due to air distribution, not fuel?

From how I understand it is because fuel pressure is at its lowest at injector #2 since the fuel enters at #4 and hits a "wall" at #1.

When did DSMers turn into 3Sers?

If there is infact a lean condition in a certain cylinder i would not attribute it to fuel distribution in the rail. Its an incompressible fluid moving at a relatively slow rate.

Wait, where is all this bad info coming from? Our cars have no problem with #1 not getting enough fuel. There is something like .00000000000001psi of pressure drop across a 1' fuel rail, I am might be exaggerating, someone with the math skills could figure it out, but it is inconsiquencial. Variance in flow from one injector to another from dirty or just bad fuel injectors is much more likely. We have been able to track down a bad fuel injector on the dyno a couple times that caused a car to detonate too easy, but they were flowing so much less that you could tell in plug coloring.

Good to know. Back in my days of hardcore DSM researching on 'Talk it was the general consensus that #2 ran leanest b/c of fuel pressure drop across the rail.

What is the proper explanation for why cylinders 1 and 2 generally have lower compression than 3 and 4?

My #2 plug discolors first on a plug swap every time. Not major but noticeable. I always heard the same things. Some myth busting on this would be great.

HAHA lean cylinders from fuel distribution!
