When you say three pipes do you mean fuel feed and returns or tank to filler neck ?

Fuel feed and fuel return ,other is what used to be the vent pipe but these days is run to the carbon canister tank,all fuel systems must be closed so no fumes,fumes are collected in the carbon canister and vented into the inlet manifold when engine conditions permit.

so would it be dangerous for the 3rd pipe not to be fitted then??

Yes the fumes are more dangerous than the fuel I would plug the pipe .
