PSA on the terrafirma gas tank skid plate....
So I had a long day whacking and bending on another project... finally finished it and wanted a quick win with installing the TF gas skid.
The thought never crossed my mind that the factory plate also... wait for it... holds the gas tank. Doesn't help that TF never provides instructions either.
so I happily start unbolting the factory skid (I wish I had heard it called a "strap" before...) and wha-boom, full gas tank right in the face. Something was still supporting it on the passenger side, so I had maybe 80-100 pounds on my face. Broke my phone screen. managed to wedge the new skid to hold it temporarily while I ran for a bottle jack and wood.
Lucked out... the fuel pump and connection appear to be unharmed, though the weight of the full tank must have been on those lines which scares me deeply.
I can definitely hear an intermittent whine, or high pitched noise now when the car is running which I believe is coming from the fuel pump. It'll come on for 1-15 seconds, go off, repeat. I swear that wasn't there before. Damage assessment?

I did some googling and found the instructions: http://www.terrafirma4x4store.co.uk/...pdfs/TF865.pdf
That would have helped! Vendors should provide these ??
It says bolts, washers, and nuts were provided for the front side, but I don't have them. The factory ones seem to be barely be long enough to cover the nut (it's a steel plate with 2 studs on it). Maybe I should get those new bolts.

Terrafirma fuel tank cradle disco ii
The tank is retained in position by a metal cradle which is secured to the chassis with two nut plates and bolts at the
rear and a stud plate and two nuts at the front.
rear and a stud plate and two nuts at the front.
Instructions should've come with the it and mfg/vendors should properly identify their product as a cradle. LR Manual should also be consulted prior to installations/modifications.

I got the aluminum one to save on weight. It's very sturdy. Probably 20-30 pounds
Yes I should have checked for instructions before doing it. it came with no hardware, just the plate, from lrdirect. I guess I thought, how hard could this be... and went for it. Lesson learned...
i need to check on the breather hose and main hoses more thoroughly. By my estimation I was supporting maybe 80-100 pounds of weight, and the gas tank was full (200 pounds). So that leaves 100+ pounds tugging on the lines. I don't see how any of those lines could support that kind of weight... but they did... for now. Like I said, weird intermittent whine noise when running that I swear wasn't there before. Any ideas? It;s not very loud.. you have to put your head below the bumper to hear it, so maybe I just never noticed it before?

The whine noise is likely that you are now finally hearing your fuel pump.
First, glad you survived!
OK, why would you hear your fuel pump (they always make noise)? My *guess* is that the top fuel tank cover is popped up so the sound is escaping from the tank now...whereas before the fuel pump sound was muffled by being completed enclosed.
Your Disco fuel pump gets turned off and on a lot by your BCU based on measured fuel pressure.
Sorry to be the bearer of bad news but you need to examine the top of your fuel tank for the fuel pump cap (you probably don't want fuel fumes wafting into your cabin or making their way toward your cats while idling).
While you are there you can inspect your fuel lines and connection fittings.

Wow lol ironically I did this exact same thing last night. Removing all my RTE protection, bumpers, and rack to be sand blasted and painted lol
Didn't want to get into a heavy project so I found what I assumed to be the easiest item to remove (only 4 bolts holding my RTE skid plate on). Low and behold, I also received a steel skid plate + half full gas tank directly in my face lol
Not even really sure how I'll get this back together after I prep / paint the darn thing.
Lovely...
