Hi Bullant,
Check out the standyne fuel manager filters, I have fitted one to my Patrol (after an $8k insurance claim for fuel contamination) and I think Swanny on here has also fitted the same.
Available from Diesel Care and Bailey's Diesel Group (and probably heaps more places)
You can get kits that come complete with the brackets custom made for your vehicle (I made my own bracket, because I wanted it to be easily checked)
