Installation Part 14- Vacuum Connection, MAP Sensor to Throttle Body
160.
Find the 30” length of 5/32” vacuum hose
supplied in the kit.
161. Form it into a loop 3” in diameter at one end with
6” of hose (97.1) beyond the loop.
162. Use two zip ties (97.2) to secure the loop.
We are going to install this so that the loop (97.3) is the
lowest section of the hose.
163.
Hold the hose so the loop hangs down, as it is in
Fig 97.
164.
Grab the end closest to the loop (97.1). Push it
onto the hose barb on the MAP sensor (98.1). This
is a tight fit and you will need to work the hose onto
the barb.
165.
Route the hose (98.1, 98.2) under the harness
(98.3) and under the brake booster hose (98.4).
166.
Arrange the hose so it runs past the throttle body
along the inner fender well (99.1). In this example, the
hose follows the Fuel hose (99.2). Note the orientation of
the loop- it hangs down in relation to both ends of the
hose. The catalytic converter is on this side of the
engine. Use zip ties to secure the hoses as far away
from the exhaust system as possible.
167.
Connect the hose from the MAP sensor (100.1) to
the lower left nipple on the bottom of the throttle body
(100.2). The other hose (100.3) runs to the distributor
advance mechanism; we connected it in the step just
before this one. Note that the nipple that has been
capped (100.4) off is no longer fitted to the throttle body
we use, so you probably will not see any fitting in this
location.
