Myself and Turboman sorted the fuel system on my Land Rover, I had a form of fungus growing in the system so I drained the system and fuel filter and whilst all the system was apart I painted my tank replaced all the old rusty fastenings with stainless steel bolts. Also replaced the filler neck with a stainless one. Well worth it knowing that the whole system is clean.
Even Turboman was amazed with the TDI self blessing technology
