CIS Rebuild Question
Hi guys!
I am rebuilding CIS and have one question regarding fuel distributor barrel: https://pasteboard.co/J1bOX2i.jpg is this some kind of filter in the middle? I can feel and squeeze something soft inside and it is in random shape but more like o-ring or maybe parts of o-ring. Saw many videos where these barrels do not have anything apart fuel holes here. Maybe I should remove this filter totally? Maybe it (this filter?) is clogged (Car was not driven for alot of time, so I'm cleaning all the lines now as they were clogged with derrivatives from petrol)? Any ideas, thanks! P.s. Car is 928, '79, 4.5L (USA type). |

I cant say for sure if that is some form of a filter or not ( kinda looks like it to me ). It does not look serviceable to me either. Do you have the WSM?

Mine doesn't have the screen, seems like a plus that yours has it. I'm sure you can clean it out with some carb cleaner. I would take off that o-ring before spraying it, though I'm sure you are replacing it with new ones as part of the rebuild.
The fuel flows through the mesh screen you are asking about, into the center of the barrel, then depending the position of the piston determines how much fuel flows through each one of those elongated ovals. Here's a good video on the rebuild process: https://www.youtube.com/watch?v=BVFu5bCKkmA
