About the 3500 fuel rail...

[Fastmax32168]

I am using the 3500 fuel rail and injectors in the swap I am doing into my 80 Monza. It seems as though the fuel rail has a restriction built into one side of it. If I blow air through the rail, it all comes out of the 3 injector holes on one side unless I block that side off. Then some will come out the other side, but you can tell it is passing through some sort of restriction first. There is a small device between the two sides whose function I am unclear on that could be the cause of this. Anyone know if this is normal or not?
Thanks

I believe the flow is different under pressure. In a stock setup the amount of fuel being delivered is more than sufficient to reach all of the injectors. With the injectors installed they don't let a ton of fuel just pour out, but meter it to whatever the particular injector, fuel pressure, and tune allow. If you were to use something wildly larger than the stock 24# injectors then it would be worth looking into having fuel delivered to each bank. As long as you are using the stock rail, stock injectors, and a fuel pressure regulator at stock pressure you should never run lean from fuel delivery.
