911RS Direct Cold Start Injectors

[geofftii2002]

Okay folks, educate me.

I need to get my hands on a set of direct-type cold start injectors (the kinds that look like little vacuum tees) for a '73 RS Touring. The car managed to spring a fuel leak and we traced it to a cracked injector. The others are also in pretty sad shape. Is this an RS unique part? Are there other MFI cars that used the same arrangement?
I already have a pretty good idea that these little things have undergone a molecular transformation from plastic to unobtainium, but I'd like to know if anyone has a line on a set or if you have recommendations to solve the problem.

A couple of pics of the location of these little buggers:

The tip of the screwdriver is pointing to the hole on the trumpet that the injector connects.

I think these squirters were used on all the 72/73 MFI cars. I don't have a source for them but they might still be available. I'd call all the usual parts places. If that doesn't work I'd try to make my own. You might be able to modify some carb jets or sprinkler parts. The size of these is not critical. The solenoid is only activated for a couple of seconds when the engine is doing a cold start. I made some to fit into the top of a custom air cleaner once. I made them out of some small syringes. They worked for awhile but the plastic degraded pretty quickly.

Thanks for your insight, Eagledriver. I'll dig through some of my junk here and see what I've got that could sustain fuel contact. I do have some calls out to the usual suspects of Porsche supply, but given some of their responses I wasn't too encouraged! Any other comments are always appreciated.

Yep, PET says on all plastic stack cars. They are not shown separate from the stack.
