i have recently removed the AC "T" type fuel pump from my Mk2 Ruby and noticed that the screw in the bottom of the pump that prevents the operating lever from moving too far forward had the end broken off. I found the end of the screw in the body of the pump and have replaced the screw with a plain threaded one.
Upon re fitting the pump I found that even with the thinnest possible gasket , the operating lever doesn't appear to ride on the back of the eccentric on the cam and ' although the pump operates ok , I think I can hear a tapping noise from the area of the pump when the engine is revved.
My questions are , 1. Has the original screw broken due to the operating lever flicking back on to the screw due to it not riding on the eccentric ?
2. Is it possible that the end of the operating lever has excessive wear hence preventing the correct operation.
I have checked the eccentric on the cam and it feels fine !!
Any help would be gratefully received
