It is a 2.8 fuel rail with 2.8L upper and lower plenum on a 3.4 manifold it's all going on a 2.8L headed 3.4 engine.
Here is my moded fuel rail.
The braided Stainless line is 8AN hooked up by an adaptor I have been trying to find for months, but I got it!
The hard line coming out the top is a 4AN hard SS line going to a flexable 4AN line for a wet nitrous system and a fuel psi sender.
The blue thing is a ajustable BBK fuel pressure reg with a RAVITEC line pulled from a bad RX7 motor.
I drilled the fuel rail head inlet and the fuel rail its self out with a 1/2'' bit it should handle far more hp now with bigger injectors the inlet was only about 5/16'' when I started.
The only restriction is the 8AN adaptor is 3/8'' on the ID.
What do you think and how much Hp do you think it could handle with up to 60 psi?
My guess is it can feed more hp than the block could handle.
