Thanks Mike Richard and J.HIDALGO,
but I'm pretty sure it comes from that terminal. The picture doesn't show it but the fuel was running right down that wire and once I removed the connector it looked like it was coming from around the threaded stud. Tightening up worked as a temporary means on pump 1 (see different thread).
How do pumps normally go, just stop to pump, or do they leak somewhere?

By looking at the picture now, I wonder whether that threaded stub can be tightened? Anybody know? I might take another look at it before ordering all the parts.

Thanks for your help.
