Im trying to remove the lower intake to do a head swap, and the fuel rail fitting that attaches to the fuel feed and return (from under the car) wont budge. I see they use clips to prevent the fuel line from popping off under pressure, so I removed the clips and tried to pull them off. They wont budge. Am I doing something wrong? I tried some PB Blaster but they're not popping off. Are they supposed to pull right off?

 

there are four screws that hold the fuel rail on, did you take those off? i didn't even take the clips off. just unscrew the 4 and the bolt holding on to the head and push to the side.

 

They are quick connects. You need a special tool to get them apart.

 

You can use the same disconnect tool as you do for your AC.
You can find these at most Auto Parts stores

 

This might help also?

 

Good pics. ...fuel lines should come apart...If not I've got a fuel rail line 4 sale
