With no picture it's hard to tell what you're talking about but I'm going to guess that you're talking about the fuel pressure test port.

Going out on a limb here, but my guess is you would test fuel pressure

If you take it to the stealership and your having fuel issues, they could plug in their proprietary fuel pressure gauge tool and test the pressure of the fuel.

also, if you are going to do any work on the fuel system, you can use the port to depressurize the fuel system. when you're done, you can also use the port to purge fuel back into the system and remove any air.

Good point. I have never used it myself.

Check out my gallery. You can also hard mount a fuel pressure gauge. Not needed on normal mods but for my turbo application it saves me a lot of time when trouble-shooting.

You can put a chrome valve stem cover on it. It'll be fine.
