oil leak

Hi all from a very occasional poster in NZ. Ive just finished converting my lovely but gutless '74 1300 4-spd with a warm 1500 5-spd unit (had to buy the whole car for dismantling, was way too rusty to even consider putting on the road) and might put up a post with pics if I get around to it...

I have an oil leak where the fuel pump mounts to the engine block. Is it just needing new gaskets? Is the spacer possibly warped or bad? Anyone else ever experienced this kind of oil leak? Any advice before I take the pump off would be helpful. Thanks!

My spirits were buoyed after my recent post on liquid gaskets and some of the excellent discussion by other XWEB members. People generally seemed to like this insight, were respectful, no one hijacked it or told me I was all messed up. So, pressing my luck, I thought I would take a closer look...
