AU won't start after replacing fuel filter

[BlueBloodAU]

Hi everyone,

I don't usually ask for advice here as a search usually turns up an answer, however, I couldn't find one today, so here goes..

Basically, I've just replaced the fuel filter myself on my AU1 sedan for the first time and having followed the instructions in my Haynes manual, I finished putting the new fuel filter in and then went to start the car, but it wouldn't start! I looked underneath the car and found fuel dripping from where the filter is after some gushed out, so went back under and re-tightened it with a ring spanner and thought this might fix it, but low and behold the car still won't start, it just makes a ticking sound when I try to start the car..does anyone know how to fix this or what the problem might be?

Thanks in advance
