how difficult is the hi pressure pipe from the pump to the filter on a 2wd saf to get off?

This pipe on my car is skooshin (not used that word since i was a kiddie) out petrol, and needs changed. Is it a bastard of a job to do or is it quite an easy one

The saf will therefore be back on the road on tues if its an easy one, and fook knows when if its difficult......
