Thats the baby i need Mark. I dont know what they smoke at Fordpartsuk as they would have sent me the incorrect part [cat converter ] after me giving them the correct 1647686 part#........after an email to them they have now corrected the hiccup and kindly included the seal as well [part # 6085380 ] however they included the courier cost of a a staggering 90 quid..... my fuel tank arrived from the UK yesterday and the courier cost via Fedex was 120 quid.....a BIG difference in size/cubic metreage and weight. Go figure !!! LOL
