One the driver's (left side) is the fuel return line. I'm no expert, but I'd think there could be problems with capping the line. At some point under the vehicle I think it turns into plastic line (at least it does on the supply side) before going back to rubber line at the engine. Some people use 7mm, 7.5mm, 8mm, or 5/16" line (There's plenty of debate about that, but I have seen all four sizes used successively.)

> I refuelled at the last fuel stop and filled the tank - within a mile
> fuel is pouring out of this pipe all over the hot engine - scary!
> I did the following as a temporary mend as it is clearly not the fuel

> Questions
> What is this pipe - I suspect it might be an air link for the fuel
> tank and if so I guess I can't seal it off
> If it isnt, what would be the best thing to do?
