Help!

I did a search found out that I need a total of 4 parts to do the full conversion. Here's my question.

I can see how three parts fit all together. There is one part (993 703 421 40)that came w/ the package that I am having a hard time to figure out where it goes go. It appears to be a rubber plug.

My best guess is that it plugs into a hole that the end of drain tube leads to. If that's the case, where is the end of drain tube and what's the easiest way to pull the other unnessary parts out of the car ?

Thanks !!

The difference in caps from '95 to '96+ was the use of a vented cap instead of a vent pipe. I guess to save a few bucks, instead of using a new reservoir, Porsche just removed the vent hose and added a small black rubber plug to the vent nipple on the aft end of the reservoir. The plug is held on by a small compressed clamp. Does this help you?

Hi Dan, how have you been ?

First of all, thanks for your prompt reply !

I fully understand the part you mentioned/described below. What I still don't get is the rubber piece that's about the size of nickle that needs to go somewhere.....just can't figure out where.

No idea what the part is that you mentioned. The part # above comes back as unknown. From what I can see the only obvious changes from early to late brake MC cap are:
- vented cap and gasket (2 pieces)
- reservoir nipple plug & clamp (2 pieces)
Can you post a pic of your mystery part?

Why would one wish to move the vent? Is it to prevent spilling or to eliminate the need to pinch the hose for the power bleeder? Curious.

Chris,

I think it's to eliminate the pinch.

I was thinking of doing this but decided not (if there somehow is overflow, fluid will go outside, instead of trunk...)

Ray Calvo

When I did mine, I cut off the overflow line at the nozzle on the side of the reservoir and added the plug, then swapped the reservoir cap for the new one. Job done.

The part that you're talking about might be a plug for where the drain tube goes thru the body. I left mine in place; why ask for trouble by removing it if I don't have to.

Last 993, I did mine a while ago like Ray did. But unlike Ray, I yanked all that tubing out of the fender. Must have weighed at least 6 ounces. Anyway, either way you do it, I don't know what part you are talking about. Maybe a pic would help identify it. I really wouldnt aorry about it AS LONG AS: you have capped the nipple on the back side of the reservoir where the hose attached, AND clamped it with the supplied hose clamp, AND used the new cap. Should be fine.

Have fun.

Thanks for the reply ! ....and I apologize for the late reply. Got home not too long ago.

I tried to take some pictures of the rubber plug that I was talking about. I did it, but the quality is not that good. It looks like a big black dot.

I will try to borrow my neighbor's better digital camera tomorrow and post pictures.

Again, the part # is 999 703 421 40 (Tuelle ??)

E.J - when you yanked out everything out of the car, how did you manage to locate and yanked out the very last end of the tbg ? Is removing the plastic shield under the fender necessary ?

Your part does not seem to be a functional piece of the conversion.
