CIS Injection Puller Tool
Is there such an animal? I seem to recall seeing one at one point, but don't remember anymore. I always use a open end wrench smaller than the "nut" and a piece of wood to sort of pry it up and out. But, I have to think there is a better way.
Better yet, someone have one close to me in Westlake Village, California area to loan it to me. |
CIS Injector puller..........
I found a large nut with the same threads as the top of the CIS injectors. With the nut screwed on the injector, use a large screwdriver with a square shank to lever against the nut. The injectors practially jump out of the manifold!
Hope this helps. |
I use the 12mm and 14mm wrenches I have out anyway. I lay the closed end of the 14mm over a nearby intake nut, and hold the open end in my hand. Then I put the open end of the 12 on the injector and press down on the closed end, using the 14 as my fulcrum.
Once the injector is popped out I use these 2 wrenches to disconnect the fuel line from the injector. I squirt a little gel lube on the injector before reinstalling too, so next time it's even easier. Rob |
Yeah, Rob, your's is basically what I do. Except I like the idea of the 14 mm on the nut. That's the problem. I'm always trying to get this piece of wood to rest on something strong.
Fred, thanks too. On this one, I don't want to remove the injectors from the lines. I did just do a search on the internet and found this crow's foot type of tool with a slot in it to put a tip of a screwdriver and lever it out. I guess I'll just stick with the old way. I do remember however a contraption type of tool. It's like this crow's foot, but it had a built in base to rest on something and a lever all connected - kind of like a corkscrew puller. Thanks all. |
I made this last spring to pull mine. It's a compression connector, a long screw, 2 fender washers, and a couple nuts...not mine:D http://forums.pelicanparts.com/uploa...1185236722.jpg http://forums.pelicanparts.com/uploa...1185236760.jpg

http://forums.pelicanparts.com/uploa...1185244405.jpg Should be the same for all Bosch CIS: Vw, Audi, etc... There also are slide-hammer types for diesels The o-rings are culprits for vacuum leaks when they harden like a rock and shrink, especially in an air-cooled engine. Also check/replace the distributor boot to see if it has hardened. Not sure what the best install lube is though....Silicone? I was once told to use a little oil, but I'd think petroleum products would not be compatable long-term with even synthetic o-rings. |
tdatk,
What a surprise, I made a tool that looks almost exactly like that! Couldn't find anything else that worked. |

I have seen a tool in a workshop manual somewhere and that was like a fuel line with a handle on the other end.
The injectors could probably be pulled up by hand by the fuel line, if they break they should probably been replaced anyway. |
Every o-ring I install from today through the rest of my life will be coated with silicon grease.
