Just bought a 01 1150 that has been off the road for a while I now have the tank off to do the fuel filter question should I be doing anything else whilst I’m in there??
Check/replace the internal pipes
Soak the tank hatch fittings in Plus-Gas or similar for a few days, otherwise they may well shear.
If you're considering removing this now would be the time to do it.

'01 model, so it's not a servo ABS.
