There will be less than the necessary amount of fuel being pumped from the tank to the engine, due to leakage past the pump, so the engine will not be able to start. A diagnostics unit might be able confirm it.

A manual check of fuel pressure at the rail will also be useful. This can be done (on the V6 at least) by putting a mechanical tyre gauge to the Schrader valve (blue cap on the end of the fuel rail). FFS is indicated if the pressure while cranking is below 50psi.

Thanks for the advice and the good explanation. I'm going to order the clip and hope that this is what is up with the car. I'm going to order the O ring too so I don't have to mess about with that at a later date

I read about putting a tyre gauge on the fuel rail too late as I was well on my way travelling to Devon by that point. I've also seen that the tank becomes unbalanced after FFS but I'm planning on draining 20L into a container anyway as its 2/3 full!

The imbalanced tank levels only occurs if the engine won't run but the starter is tried repeatedly in a vain attempt to get it going. If the car is actually driving then the levels will equilibrate as normal. However, some extra juice in a can is wise if you do have incipient FFS.

Cheers for all the advice. The filter housing had undone completely seperating itself. Fitted a clip and new o ring so it ran fine when i just fired her up!
