guys i cant find out the name or the product code for the fuel tank strap that goes over the tank made from flimsy metal that rusts of incredibly easily apparently...

its part number 17 in this image, however i have a discovery 2 td5 2001 and this image is for disco 1 and the straps are different apparently...

i need to get hold of one and for as cheap as possible

got a week to get it as the tank is still out and on the floor while the rear chassis legs and cross members are being changed!

try esr4549

that's great! thank you! famousfour seem to have it in at £25 which is much better than 70 that the rest are quoting online
