Gas Tank removal on FX4.

[Geno1965]

I have tried all suggestions on removing the fill bung for Trans Axle/gearbox. How would I go about dropping the tank out ?? I have noticed that the drain plug is also stuck up above the rear box section of exhaust. There might to 20mm between sump plug and exhaust. If I could get the fill plug removed I might be able to drain some of old oil and top up . Depending on access. I hate being beaten but don’t want to make things worse by removing something I can’t put back. Sorry about all questions but limited space and warm bodies make it difficult. Thank you all so much. Will try a video tomorrow night and show you all the clearance issues I have. Thank you again .
