He has already fitted the Sard plugs to his harness. The bottom of the connector hits on the fuel rail before it clips onto the injector properly. If he decides to change injectors again later on the plugs will have to be changed again.
Hmmm. I remember having to phone a friend to make the O rings and adaptor collars fit properly but I don't remember having trouble with the connectors (well, once the loom was butchered anyway).
Just another thing to add to the list of why Sards are bad in SR's!
