Fuel distributor rebuild

[prebordao]

I'm curious... as my FD will probably have to be rebuilt soon, I wonder if removing and fitting it is a job within reach of most of us... how hard it is ?

There is a lot of high fiddle diddle stuff in there that needs special tools. If you just want to open it up and clean it, there are a few who have tried it (do a search). Best just to get a rebult unit and exchange.

prebordao,

Are you asking if it is difficult to remove it and then replace it with a rebuilt one? In that case, it's fairly easy. Just unbolt the fuel lines that run to it, and it comes off pretty easy. There's not a lot of room, but it can be done.

When you are removing it, be careful that the plunger doesn't drop out of the bottom - it does not like to be dropped.

R&R is very easy. We handle rebuilds if interested.

Yes, that was my question. How hard it was to exchange it myself ?
I'll not attempt to rebuild it !
Can it be done without lowering the engine ?
I'm also afraid that when you lift it from the throttle body, all those springs and o-rings come out, or are they fixed in place by the diaphragms ?

I have done mine a couple of times without lowering the engine. It's tight, but not too hard.

No - it comes out as a single unit. All the small stuff is inside - only the rebuilder needs to worry about that. The plunger in the bottom is the only part you need to worry about.

Becarefule NOT to drop the plunger there is no stopper. It a tight squeeze. I just removed mine, The eight small fuel lines can be removed with little difficulty, Than the two big one are more difficult you need to remove the U rubber as there is not enough clearance than the three screws on top with i used the head of the screw driver and connected it to a torque wrench. very little working space. according to the porsche worshop manual you should remove the hex screws on the AFM and remove the whole unit together but it's up to you.

Here's the best thread for the fuel distributor. He does the rebuild, but you can see what the fuel distributor looks like.

Picture of just the fuel distributor that you will remove - it's held on by only 3 screws and an "O" ring at the bottom.

Thanks for the pics, great help !

And what about rebuilders that you had good experience with ?
I've been looking at the info on the SpecialTauto site, but would like to hear from "real" customers...
