Same here, if its empty, its just a fiddle to get the pipes off... Has to move to the filler side to get it out as it drops out from one end. Once the straps were taken off, a job in itself if they are rusted up, the tank just sat there.... Goes back in filler side first, then shove up the other end.

Thanks guys, now it's crystal

Should the tank be loose after the strap from below is taken off?

I have it, and the top strap from filler side off, the filler etc hoses off/loose.

And there is zero movement in the tank.
Even tried jacking it up, with a piece of wood in between to even the load, no movement except the whole car lifting..

Trying to get the tow bar off but not having any luck on it yet, gotta get the angle grinder for the thru chassis bolts...

when I removed mine it came out by pushing up on the filler side the pulling down on the opposite side

The plastic tank isn't heavy. Remove the pump and syphon out the fuel first, then undo the clips on the filler hose and breather, then undo the bolts on the tank cradle and drop the tank. I've done this laying on my back and on my own many times now. Hardest part is lifting the boot carpet to access the pump, although cutting a neat flap in the carpet saves even that effort.

Got it out yesterday after using the angle grinder and a dremel with the small 38mm discs.

Both side towbar mounting brackets need to be removed.
And as they may have been on since new, I had to cut the nuts off the thru chassis bolts.
Nice design, atleast on the right hand side, not too much space between the bolt and tank, got some minor heat damage on the tank now. Cut a little, grab some roadsalt etc grime ice and cool the bolt down, cut a little etc.
Had the nuts cut off and tried turning the bolts, no luck, nada, zip...

Spent atleast one 6Ah battery on my TW700 hammering them back and forth before they gave up and loosened enough so I could hammer them out.

Plenty of "loose" corrosion in between the tank and chassis etc, but it did come out.

Fiddled the new fuel pipes in and hopefully I got the two correct way around that go on the rear of the filter housing.

Getting the tank back just needed some rough handling for the filler hose to be pulled down from the trunk floor for it to have room to pivot in.

At this point I felt it was too crowded in my "garage"tent due to too many f**ks flying around, so I quit and went in to eat some reindeer and have a shower.

Yes, my tow bar bolts were a bitch to get out.... new ones fitted, with plenty of anti seize

Wow this makes me feel really lucky.
When I needed to take it in to get the rear chassis welded, I took the tow bar off with no trouble at all.
Took almost all of the rear interior "furniture" out to avoid cutting the carpet.
Then blokey/welder took the tank out and struggled.
It was nice to be able to paint the towbar, make a proper hole for the safety clip for the trailer and fit a new electric plug.
