Got fuel dripping (steady 1 drop per second) but only when the engines running so hopefully rules out a leaking tank. Seems to do it regardless of the fuel quantity in the tank. It’s right at the front of the fuel tank tray. A question I have is does a RR Sport 3.6 TDI V8 on an ‘07 plate have the two lifter access points under the rear seat please? Or is that just for models with the tank mounted side to side rather than front to back as mine is mounted. If does I think I’ll attack it that way rather dropping the tank as a lot of YouTube videos appear to be leaks coming from cracks in the plastic on the lifter pump or the filter. Also, am I right in thinking that is the location of the filter on my car please.
Thanks.

All L320 RRS have the front-to-rear tank and none are accessed from below the rear seats.

Start with the fuel filter housing / filter. You can see it just at the front of the tank in your pictures and it's accessed by dropping the large plastic transmission undershield. There's a water-in-fuel sensor drain point that might be leaking, otherwise perhaps replace the filter and sensor with a new one of decent quality i.e. OEM or LR, not cheap ebay items. 2012 SDV6 - it's missing a couple of cylinders

That sounds like a good starting point thanks. I’ll keep this thread posted with how I get on. Cheers.

Thanks to RRSTDV8 for saving me the hassle of dropping the fuel tank only then to find that’s not the problem and having to refit before moving onto the filter assembly. I’m sure you’re correct in your diagnosis and that is certainly where the fuel appears to be coming from. I’ve ordered a new filter (OEM) and am wondering, when I replace it, is it sensible to leave the water drain open to help bleed the air from the filter or is that floored thinking? Thanks again.

Thanks to RRSTDV8, you were spot on. Old fuel filter in poor shape and way overdue a change. Swapped it for a new one and fuel leak is gone. Thanks again for your help.

Damn, that’s one rough looking fuel filter. I changed mine not too long ago and it looked new compared to that. 2011 RRS HSE Luxury 3.0 TDV6 Fuji White on Ebony/Ivory

Glad you got it sorted out relatively painlessly.

You just need to figure out which garage didn't change the filter when it should have and then avoid them in the future.  2012 SDV6 - it's missing a couple of cylinders
