Hi. I don't seem to be able to get my tank strap really tight and especially when full it squeaks quite a lot and I think allows the tank to settle a little.

 

Am i missing something? Is there supposed to be a diagonal strap too? Its a 1971 mk3.

If that's a genuine 71 shell then someone's's fitted the wrong fuel tank. You've got a 7.5 gallon tank there frome a later car thats designed to be secured with a diagonal strap in the indentation in the tank but it requires a different mounting bracket on the floor, don't know if the bulkhead bracket is different. A 71 should have the smaller 5.5 gallon tank that is secured with the strap that you have currently fitted to your car.

Here are the tank configurations showing the various straps by yr from

A Mk3 would never have that strap arrangement originally and that strap won’t work well with the late tank as there’ll be too much weight pulling the tank through the strap.

Aha, ok the plot thickens. I think I have a slightly later shell, this must have been done over 30 years ago though! I have old bits and newer bits.

So sounds like I could have a MK4 shell and tank, but a MK3 strap.

Is the answer just to buy a MK4 strap then?

only if you have this bracket in the boot too...

South African last models from the eighties have exactly this strap with this 35 litre tank. You need to check if there is a thin rubber insertion between the tank and the straps. There would also be a rubber insertion on the floor support.

Hi yes i definitely have that, i assume there is something at the other end as well then.

Thats interesting. Mine doesnt have that though. There is some fibrous dead deadening type material between the strap and the tank though.

 

Sounds like i will get hold of a diagonal strap then take the tank out and see what i can do. Cheers all.
