Fixing Yanmar 2GM20 injection pump leak

[@MiltosMimis]

Hi, what size of a spanner used to undo the fuel lines from pump?

Hi, the fuel line nuts are 17mm. To the spanner I used in the video, I cut a gap to the ring end to get it around the fuel line, but it was not very helpful in that tight spot anyway. The delivery valve holder nuts are 19mm.
