I'm going to guess that it's either the pressure or the return, and that the wider rubber hose is the vent?
I had that above the tank on my old 1990 COrolla, and I simply cut out the bad spot and spliced in some hose with clamps, since that car's body very closely resembled the fuel line in your picture.

 

I might actually try that thank you

 

welcome to the rusty crusty club
i need to get mine better inspected in that general area, i saw from a distance while at the rear of fuel tank dealing the neck tube
sprayed some sheep fat on the area just in case


which of those lines, i see two in question
i was just looking at a diagram yesterday with all parts and number for it all

 

The

the one that’s soaked with fuel that’s the second metal line from the left and yeah I’m from New England so rust is common

 

I just bought a 96 Corolla yesterday and today when I went to our gas I saw some on the floor i panic lol I took a look under and couldn’t tell where it’s coming from!!! Friday I’m headed to shop to find out what needs to be replaced!!

 

You should be able to see which pipe is which by looking by the firewall. One is the high pressure gas line from the fuel pump to the fuel filter. One goes to the EVAP charcoal canister. The third is the return line. And then there are brakes lines too.

You would need to put in your VIN to make sure this is the correct parts diagram.

I think it might actually be a return cause it only drips, I would assume the feed has high pressure so if it was pressure it would be spraying, am I wrong for thinking this? I’m learning mechanics so there is a lot I’m not sure of yet but this is my daily

 

You're probably correct. The EVAP pipe may only have vapor in it too, so that wouldn't be dripping.

But why not verify which pipe it is in multiple ways?

 

From looking at the diagram the middle fuel tube line is from the canister, but I dont know what function of that is for

 

The diagram could be incorrect. I wouldn't trust that completely.

 

I looked near my firewall and it appears that the return pipe is more toward the passenger side than the EVAP pipe and they are next to each other. I couldn't see exactly where the high pressure fuel line was, but I think it's probably the farthest toward the driver's side, so the diagram is probably correct.

In any case the return pipe and EVAP pipe have the little spring clamps, so they should be easier to repair compared to if the high pressure line were leaking.

 

the high pressure tube should go straight to that fuel filter ?

speaking of high pressure!, i have been hunting down the best method to depressurize the system, there does not appear to be a fuse for the pump in the engine bay to take out, start car and let stall to relieve pressure

 

The return line and evap are $50.25 each where I’m from and dealer has both in stock so I’m either going that route or I might just use a hose, only need it to pass inspection
