Audi A6 fuel pump (in tank) seems to have a third pipe that leaks
On top of the fuel pump there looks like there is a third outlet. All the videos I
see on YouTube only have two outlets. I've searched for replacement pumps
and seen one that look similar to the current pump installed except the third
outlet looked sealed (as in a spigot that was never open).
This has started leaking after the fuel pump was changed. The garage that
fitted it has said that fuel should not becoming out of it (even though I have
seen fuel dribbling out of the top of it).
Should I seal up this third outlet?
