Noticed it when I pulled into the garage. Opened hood and noticed it pouring out from the bottom line attachment. Any guesses on if it’s the clamp / hose vs the actual tank being bad ? Best way to check ?

Stock plastic tank on your Cobra? If so, it happens over time with heat from the engine bay.

Get in there and find the leak to confirm and replace the tank if necessary. They’re fairly cheap and readily available.

Yes.

Got back under there and took a picture. What’s the hole on the left? Is something missing ? Looks like that’s where the sensor would be if I’m not mistaken….I don’t have any lights on the dash so unless the previous owner removed the sensor and did a bypass I’m not sure why it would be missing

Yup, It is the level sensor cavity.
The sensor goes up in and is surrounded by a cavity that creates a float rail.
Not used or part of the gauge cluster after 99.
Open the cap and you may see the foam float.

I have no idea whether the Terminators even had that sensor mount type of tank or float. Maybe the tank was replace once already.

The Dorman unit is good.

You could also get an AL unit with a side level indicator and never worry again..

Thank you very much for all the info!

One additional piece of information that may help point me in the right direction - the tank only leaks when it gets really hot in there. Would that lead you to believe it’s most likely cracked or could still be the clamp / hose?

Pressure is what causes the leak. So yeah, it most likely has a crack that only leaks when enough pressure builds up inside of it.
