I've got an 88 camaro V6 2.8 liter-- Under the plenum just behind the throttle body, there's a black cylinder with an indention on top and a vaccuum line plugged into it. This cylinder is attached to a plate with allan screws. It looks kinda like a spray paint can top. It can't be a fuel pressure regulator, can it? I called GM parts and they said the 2.8 liter engine doesn't have a pressure regulator. Plus the fuel rail goes uninterrupted from the in line filter, all the way to the schrader valve.

Check your e-mail joel007, I have just sent you a couple of pictures from the service manual. Take a look at them and see if this is what you are talking about.

Sounds like a pressure regulator to me.
I've never heard of a fuel injected engine that doesn't have a fuel pressure regulator.

I've never seen a fuel injected car without a pressure regulator. All the GM multiport systems I have ever looked at had it built into the fuel rail. Normally a can looking device with a vac line on it.

Now if it were a chrysler product, they have been putting those on the fuel tank module. Fuel tank module, another way of saying it costs toooooo much.
