I'm in rhe early pocess of doing this and aready encountered a few problems. I think I snapped the low pressure fuel fitting (17mm fitting with the 14mm compression nut). I was loosening the 14mm nut when I heard a snap, looked at the 17mm fitting knocked loose. It's difficult to put the 17mm counter wrench in there while loosenng the 14mm nut. So 'll have to remove the pump with the low pressure line with it.

Another problem are the three pump mounting nuts and studs. The studs are turning with the nuts, so I'm gonna be pulling the studs out and then try to separate the nuts from the studs off the vehicle. Anybody knows how long the studs are?

Anyway I have a question about replacing the governor shaft o-ring. Does the governor need to be disassembled completely? Or can the linkage be removed and the shaft pushed out of the body to expose the shaft o-ring?

 

You can unscrew the gov shaft just enough to remove the oring. Count the turns out and turn it back in the same amount.

 

So then I don't have to mess with the linkage/governor inside the pump. Thank you.

How about the throttle shaft oring and the manual shutoff oring? Can they be replaced without removing the top half of the pump?

Edit: Looks like I'll have to remove the top half anyway and remove the Lever assembly inside in order to replace the fuel pin oring. Still, I don't understand why the pin secured by the ***** has to come out, if anyway the oring comes out from the outside through the plug near the throttle shaft. Can anyone explain?

 

The shaft behind those little ***** has to be removed so you can remove the lever assembly that rides on it so you can get at the small fuel pin up farther in the top.

I'm lucky that both my pumps had the screw in stops for that shaft, not the ball bearings.
