X-Y problem time, I think. How do you know it's a rat? Your comment on the question says that it looked "chewed and not cut with a tool". This is precisely what wear looks like, and this is backed ...

Best way to repair a rotten fuel line?

To be honest, if part of the fuel line is rotten, I'd be tempted to replace the whole line - chances are the rest isn't far behind... Modern rubber hoses should last a decent amount of time, they're ...

I'll preface this with the caveat that I haven't replaced the fuel filter on this specific vehicle before, and my advice is based on experience with other cars. I do think it's good advice regardless. ...

Engine sputters when turning left corner

My theory is you have a stuck float in your carburetor. This is causing the fuel bowl not to fill completely. When you go around the corner, the main jets are without fuel (sucking air) and this kills ...

Will my fuel tank empty if I leave the fuel lines disconnected?

No. It will not evaporate by much at all. I would say it would be nearly unnoticeable. If you are concerned stuff a decently fitting clean bolt in the lines or something to plug it up like a rubber ...

What is a safe procedure for replacing a fuel filter on a 2000 Toyota Camry?

Do not crimp the fuel line. As long as you put a rag under the filter, you won't even notice the spray. While the rail may be held at a fairly high pressure, the line is small, so there isn't much ...
