Found under the hood of my 92 player's car. What is it and what does it do?

fuel line?

Is their something under it? Looks like something to keep your fuel cool,the cooler your fuel the more condense it stays, a lil more hp you will get. My old camaro i had fuels lines wrapped like a coil inside of a small canister. I fill the canister with ice before every run i made down the track.

You're thinking of a Cool Can. This thing just its there as it is. I think it may be a pressure damper or something. My Buick has something in the tank called a pulsator to smooth out the fuel flow for the injectors, maybe something like that. Braided hose = definitely aftermarket.

my 92 bird with a 3.1 has one mounted to the front if the intake
