Well for anyone who missed it, I didn't make it to CRaP this year in a Capri

The GL has decided that it no longer wishes to engages gears properly so that was out the window, and on the way to work the day before CRaP the fuel tank straps make the brave decision to break away and try to begin a revolution
Straps had totally shat themselves and snapped off. Only thing I had in the car was a little bag that has been in it since 2011 when I got the car, never knew what was in it and lucky for me there was a tow strap!
One quick bodge lashing it around the axle and rear bumper meant I could nurse it home and order some new straps, and for good measure ordered some new bolts as well as reading previous posts everyone suggested they would snap.
To my surprise they didn't! Soaked the originals in wd40, left it an hour and went out with the hope they would snap as it would be easier to get them off, to my surprise they both 'cracked' under the pressure and the thread broke and came straight off!
This is what was left of the original tank straps...
Managed to fit the new tank straps this evening after they were delivered yesterday so all sorted! Didn't take a load of pictures as my phone was going flat so didn't want to drain the battery. Took the opportunity while the tank was hugging to floor to give it a quick clean up before soaking it in hammerite paint, and also painted the new straps before fitting them because I don't want to be doing this again in a hurry!
Tickover have some stainless steel straps but are a bit pricier, though in hindsight would probably be better long term as will be there until the sun implodes
What I can say for anyone who reads this later with similar issues - check your bloody tank straps!! Changing them before the whole tank falls on the floor would be much easier than this saga (trust me) and is easy enough to check as well - if they look rusty and fucked, they probably are.
If you are lucky enough to be as supple as me, you could probably do the whole thing without needing to jack the car up either as I didn't! Only used the jack (with some wood) to lift up the petrol tank because my god does it weigh a tonne - especially if filled with fuel!
Whatever you do, don't go full retard and jack straight into the tank and risk punching a hole in the bottom of it.
Even though the old bolts came off, I decided to fit the new bolts and keep the originals as spares if I need them in the future, and then covered the nut and the bolt in so much grease I was half expecting them to start singing at me, but definitely worth doing as made putting the straps back on so much easier. Use a deep socket to put them back on again, ratchet spanner almost certainly won't fit and otherwise will take ages.
Also, don't overtighten them! You obviously want them tight, but if you tighten it too much it will hug the bottom of the boot which will inevitably cause issues later down the line. Mine had some pads on the top/edges (one had fallen off) to protect against the underside of the boot
Anyway, roll on CRaP 2024!!
