On page F 26 It said to "Fill fuel pump housing with special grease before installing"

Re: FUEL PUMP REBUILD 912
Not applicable to the 912 pump unless pump has been changed to the earlier version
This is the pump you should have. No grease needed.

Re: FUEL PUMP REBUILD 912
If you already rebuilt it then just pack the cavity with a good high temp wheel bearing grease. I hope you preloaded the diaphragm as per the above the manual.

Re: FUEL PUMP REBUILD 912
I did not. Because I rebuilt an existing pump that I had on hand.
I am not sure what to do to preload this pump ?? I will be taking the old pump off the motor. Do I measure from the face of the flange to the face of the lever ??
I have not tightened the screws on the rebuilt pump yet

Re: FUEL PUMP REBUILD 912
The manual which is available on the main website gives a good run down on the rebuild but in essence you must ensure that the diaphragm is flat across the two halves as you tighten it down. I use a 10 mm bolt with nut set to the correct length and I hold the pump in a vice with the bolt extending the diaphragm to the correct position. If I remember correctly the dimension is 35 mm but do not rely on my memory, it's crap a lot of the time.

Mac, you can use a 1 1/4 inch (31.75 mm) piece of wood to fit into the pump cavity to set the preload on the diaphragm.
Use a vise to carefully apply the pressure against the piece of wood and lever and to hold the pump while you tighten the screws.
