I was wondering if someone could give me newbie instruction for replacing the petrol sender unit on my 1970 Amazon. I have a new one from Brookhouse.

I'm hoping this will cure my errant petrol needle which is still boogying to the non-existant radio.

Thanks

Tom

Disconnect battery !!

1. remove all of the junk from the boot.
2. Lift the damp bit of old carpet.
3. The sender is the round thingy in the middle of the tank.
4. remove the electrical connection (s), noting where they go
5. Undo the teeny little nuts
6. Lift out the sender, (note which direction the float arm points)
7. While you are there, have a peek into the tank to see if its full of crap, if so, make sure your filter gets a regular change, (you do have an in line filter fitted??)
I was lucky, inside my tank was pristine.
8. Plonk in the new one.
9. Use new gasket if yours is gubbed
10. tighten down evenly
11. replace connections
12. throw all the junk back in the boot
13. sit back and enjoy your new stable gauge....
14. I always had a spare gallon in the boot, just in case.

No more than 15 mins start to finish, (+ 30mins looking for that wee spanner that you know you have somewhere that will fit the tiny nuts before you reach for the mole grips.......)

Don't use a lighted match to look inside the tank, that would be a bad thing and leave you like one of those cartoon characters with the surprised look, black face and sticky out hair, (or worse).

Also note: You will crack your head on the very pointy bootlid latch several times as you work on the sender, young children and ladies should be kept at a safe distance to avoid offending them as you shout "Oh BOTHER, that was very painfull".....May be worth wearing a yellow hard hat, even if this is the final proof to the neighbours that the weird guy with the old banger has truly lost it and needs to be humoured at all times....A thick wooly hat may suffice, (will also soak up the blood), so long as your gran used 4-ply wool when she knitted it...Personally I wore a full face Motorcycle helmet, I've lived in my current home for a long time, my neighbours know what to expect and are no longer surprised...

Gerry,

Thanks very much for this funny, but more importantly useful, post.

My fuel gauge is similarly frisky, and after reading that I might well be tempted to have a go at replacing it.
My bootlid springs are knackered so my neighbours are quite used to the odd "fusking bell" expletive when it lands on my head.

my bootlid springs are also knucking fackered. Is it difficult to replace them, or is there any possible adjustment (apart from bootlid getting lighter with rust!)

There is some adjustment you can do to the bootlid springs. If you look into the boot under the rear shelf (the one behind the back seats) you will see that the end of the torsion rods can be clipped into about three different notches giving different spring pressures. Don't underestimate the amount of force needed to move it though!
