    Default Critter damage to fuel line

    So some critter decided to make a meal of some of the fuel system components on my 1989 Celebrity 2.8L. A few wires to the fuel pump and also the end of what I believe is the vapor line to the fuel sending unit.
    You can see the damage pretty well in the video:



    The wires are no biggie, but this is my first A body with nylon fuel lines, so I have no idea how that vapor line that was totally gnawed off connects to the steel line from the fuel sending unit.

    Any photos of an intact connection would be awesome.

    Thanks,

    Dan

    Honestly I would go o a junk yard and pull a Buick century or oldsmobile ciera 94-6 fuel vapor line from the charcoal canister all the way back to the tank it's a 90degree rubber sleeve fitting . You can get creative and adapt a cooper fuel fitting and clamp that to another fuel line hose to make the connection

    Thanks, but I really didn't want to take it that far. If it's just a rubber 90 degree I might be able to rig something up after I splice in some new 5/16" nylon line.
    Dumb question, but how important to the performance of the engine is a fully intact vapor line?

    Just bad smell of gas and won't pass emissions . Like leaving a gas can open you can smell it just the vapor but no hinder performance

    Older than 25 years and there's no emissions in CT.

    Sorry to revive this thread from the dead, but I've been searching everywhere for this info. Are the fuel lines in the A-bodys (specifically a '96 cutlass ciera 4cyl) 5/16" diameter? I've got a leak under my drivers door and it should be a straightforward splice and reconnect, but I can't find the inside diameter measurements anywhere. None of the big 4 auto stores, let alone the GM/Olds dealer were able to provide any info.

    I'd think 4 cyl cars are the same. The pressure line should be 3/8" OD and the return line should be 5/16" OD. They don't go by ID.

    Just thought I'd update this saying you are indeed correct. I replaced the damaged section of the 3/8 sending line (I used the dorman kit found here https://www.autozone.com/fuel-system...air/193137_0_0 )

    It worked like a charm and installed in seconds (I used zip ties instead of the fasteners they give you, because you need a special tool from dorman to attach the fasteners.....go figure)

    Until I found out there is also a small hole in the return line, at the EXACT place as the hole in the inlet line....so I didn't notice it when the inlet line was spewing out fuel. Oh well. for 7 bucks each, you can't lose.
