Oh ok, makes sense now.
There are usually at least 3, one is from the tank, one go's to the pump, and the other returns back to tank. There could be another one with is a water drain off. Fortunately you don't have to worry about them being pressurised, and this doesn't happen until the fuel hits the pump.
They are usually mounted on the bulkhead on the back left (as you look at the bay) although they could have moved it, as I haven't seen a mk6 engine bay, but it is pretty distinctive.
something like this i would imagine...
