"kit" to install Webers

[Wyvern]

I have some 40s and manifolds with linkage.

Can anyone help me with a question and a resource please ?

(75 911S with CIS to be removed)
Searched MANY of the threads and the info, I either didn't find in the 100s of posts researched.

Are there, do I need Insulators / Isolators / CIS injector block offs(want to be sure to use the right word and to answer my question as to if the manifolds block the ports or do I indeed need something?)

If so where and what do I look and ask for.

Looking to purchase the gauge and reg from our host.

If the parts are available will make ONE purchase for all needed.

A good resource for fuel filters would be a huge help as well


Thanks gents

Many, many threads on people doing this, just search and read. Tons of info.

Thanks guys.. yes there are many threads on this ... but nothing clear.

One poster says bolt em up another says MUST use isolators / insulators to block the injector ports half round in the head.


I found this on another site . but still need to specify port size and current system .



How about a hint on what to search for (or where to go) where the info is not debated .?

Porsche used insulators from the factory. Seems that answers one question

If you look at our hosts small parts operation, for a early 911S that used webers, you'll find all the parts you need, as he has patt diagrams showing how a early 1970s 911 went together. You essentially need to recreate the set up, but with tweaks for the CIS.

James is right, there are many examples of conversion. His Zenith conversion is a good example. Zeniths are essentially the same as webers.
