werd...

The big round thing in the pic is a FMU, used in the 90's to add fuel when under boost.

The thing on the fuel rail that you asked about (i am guessing), is a fuel pressure regulator. Its used for a set fuel press adjustment.

 

It's something you get rid of and get some real engine management.

I see you also have a missing link installed on your MAP sensor.
Not a big fan of these hack jobs.

 

LOL @ Missing Link.

That went out with dinosaurs and body kits about 10 years ago.

 

purple piece is the fuel pressure regulater that blue **** is a fmu basically it just adjust the fuel pressure in the car if your runnin turbo nitrouse supercharger.

not worth gettin it a ghetto way to increase fuel just get your car tuned

 

FMU and the missing link . I remeber those things back in the day like 2000 cool things back then. But now there is like chrome which is cheaper

Purple thing mounted on the fuel rail is the Fuel Pressure Regulator...or FPR. It regulates your fuel pressure.

Blue thing mounted to the firewall is a Fuel Management Unit...or FMU. It is basically a rising rate fuel pressure regulator. You feed a vacuum signal to it and as boost is increased, so is fuel pressure by a certain ratio determined by it's internal diaphragm.
