What does this EFI part do?

Since you guys know everything as PaPitt says...

Carry over from a question on Norcal Broncos...

On the fuel line, no electrical or vacuum connections. Not a regulator.

Maybe something to lessen the highs and lows of the fuel pulse?

Originator thinks it is from a 94 Bronco?

I have seen them, just not on Mustangs or Explorers, now I am intrigued on what it is?

It's a fuel pump. Its supposed to mount on the floor under the gas pedal. When you mash the gas far enough, it pumps extra fuel to the carberjectors--like NOS!

I saw something calling it a Fuel Pulse Damper. No idea why it'd be necessary.

Pressure spike damper. They are found on the returnless explorer rails.

Thank you all for the replies...

Vw, my 71 bronco has a 2000 Explorer motor, the one on that fuel rail has a vacuum line attached... I guess they come in different flavors...

Hi, the thing on the fuel rail with the vacuum hose is a fuel pressure regulator. Good luck

The explorer damper has a vacuum line.

This caption explains what it is & why it was added. The pic shows what the one for '94-96 F-series & Bronco V8s looks like:

Something that looks similar with a vacuum line is a fuel pressure regulator:

They're not the same.
