The pipes are flanged formed but there was no rubber olives!Has you're old pipe got brass olives? Later ones will have a flange formed on them to take rubber olives
Yep your spot on, the lift pump had a small amount of rubber debris in it and the filter had a damaged one, took some removing. Many thanks.There should be. Are you sure they didn't stay in the filter housing/lift pump/injection pump. They usually get squashed into the threads and need digging out with a pick.
