Hi All

Have seen this on an unrestored car…does anybody have anymore details…? I assume the 022 refers to the 1.7L but what about the other number?

Any insight would be appreciated…thanks

SUMMARY OF POSITIONS OF VACUUM HOSES BY EXPERTS.

This helps summarise what can be known with some certainty about the variable vacuum hose layouts.

Version 1.
the late Cap'n Krusty.
credentials are impeccable. (IMG:style_emoticons/default/beerchug.gif)
he states both ports on dist connected to both ports on TB.
both ports on TB are opened up in casting.
he lives and works in california.
he works on a 1.8 L jet before it hits the showrooms.
see posts extracted from thread date (2010)
he is seeing cali cars from the start - they are as per wonki, starbear and van b.
EC-B (California and EPA emissions sticker).





Version 2.
Clay Perrine.
credentials impeccable. (IMG:style_emoticons/default/beerchug.gif)
he states only the retard vac port on dist is connected to retard vac port on TB.
advance port on TB is capped/closed.
retard port is opened up and connected to retard on dist.
vacuum advance line on dist is on but tucked under dist and left open.

Dr. 914 backs this up.
he'd know. (IMG:style_emoticons/default/beerchug.gif)
adds that version 2 comes into effect jan 01 74.
versions 1 are being made after jan 01 74 so does not necessarily supersede.



this would fit with marathon blue car = EC-A.
EC-A is California and EPA emissions sticker.
Fits with marathon blue car idle tune sticker though not with hose layout now on car in photos.


Version 3.
others claim there is a TB with an open advance port and a closed retard port.
only the advance on the distributor is hooked up to TB.
in this type the retard hose is fitted to the distributor and is tucked underneath.
though it looked like zonedoubt's car is a 75 and has a 067C TB.
however there is an image of a 067A TB with the same configuration so they likely do exist in 74.




--------

There is known to be an EC-B emission sticker and it is only 49 states / EPA.
Not california certified.
At present i cannot link it to any of the three versions.
There would be a idle tune sticker to go with it showing only a hose to right of dist on tune up sticker if version 3 is EC-B 49 states?

---------

Below images of what each version of TB would look like.

I have seen images of version 1 and version 3.
I have not seen images of version 2. i'm guessing its advance port is blocked or capped somehow.
