just done one on the wife's Evoque, hope the L494 is a bit easier to do
4.5 hours to get the diff hanger bolts out to drop the tank  2014 L494 5.0 SC

Afraid not.
Exhaust off, propshaft off and lots of other bolts to remove. 2021 L494 D300MHEV Autobiography

Lol
Look forward to that job then 2014 L494 5.0 SC

Yeah.
I’d been hoping to put a Saturday aside, drop it, coat it in hammerite as a pre-emptive measure and pop it back.
From what I can tell it requires specialist tools and more stripping down than I’d attempt on the driveway.

spray oil between the tank and support.

Coat the underside with used oil

I might look into lanoguard if there's enough access to spray it on top of the panel below the tank. 2021 L494 D300MHEV Autobiography

Lanoguard is great.

Just got an advisory on my MOT regarding corrosion on this item. Is it just a 'cover' or is it critical to the support of the fuel tank? RRS HSE Dynamic SDV6 2014

Critical I believe.
The videos I’ve seen of replacement show the support and tank being removed as a single unit so I assume that’s all that holds the tank to the car. 2021 L494 D300MHEV Autobiography

Yes, the cover holds the tank in place
