What's these for.

1st picture looks like a tyre valve on the inlet fuel rail. What's it for?

Second picture. Shows rollover valve. Does this link up with the carbon canister? The other tube to the fuel filler. What's this one for. Fuel return?

Any problems with these. Thanks folks.

First one is to attach a fuel pressure gauge so that you can check and adjust your fuel pressure.

.....Or safely release pressure to work on fuel system.
