fuel line disconnect??

how do you disconnect the fuel lines down by the fire wall? push and turn somehow or other,there kind of rusty and i dont want to forse them the wrong way . thanks

when starting a post its always good to state the year and engine of your car. the fuel line can be disconnected with a tool from autozone or try to hold down the taps while pulling apart. I didnt have to twist. good luck.
p.s if your worried about rust it wouldn't hurt to spray them down with p.b blaster or wd 40 and letting it sit for a while.

thanks hitman,i did borrow the tools from my neighbor. the donor motor is in bolted up loosly for tonight ill finish up all the loose ends tomorrow.
