Mech. boost guage install using alternate line and mounting position

**deadmeat** · 3-31-02, 14:07

Here is another method for installing the autometer boost guage.

supplies needed: cost ($us):

boost guage $20-$100
teflon tape $1.49
(2) 1/4" screw in-to-hose nipple $1.29 each
(1) 1/4" 3-way w/female threading $1.65
(22) electric wire butt-connectors $1.99
(8) quick connect hose clamps $2.99

**DO NOT buy 1/4" nipples. they turned out to be way to big. 1/8 would be more appropriate. these were the only size i could find, so thats what i went with.**

here is all the equipment you should have...

I. Preparing hardware for installation

Step 1:
teflon the threads of the hose connector on the back of the guage;
teflon the threads on the two 1/4" nipples;
teflon the threads on the hose connector (far right in picture)

Step 2:
screw in the 1/4" nipples into the right and left side holes on the 3-way split
**you may need to buy another locking nut for the hose to the guage, as mine didnt want
to screw in properly.**

fasten the larger female locking nut to the back of the guage

II. Placing your guage

1. go out into your car, and decided where you want to mount your guage. i mounted mine near my
guage cluster. after decideing where you want your guage to go, decided on an appropriate route
to thread your hose through.

i found a little grommet near the clutch master cylinder to run my hose through, then i ran it up
through the back of the dash, and to where my driver side air vent is. i mounted the guage in there,
so it will be visible when i'm driving.

III. Tieing into a boost source

1. open your engine hood. at the back on the firewall, behind the throttle body, there will be
all kinds of interesting tubes.

2. next to that long rectangle box, on the left side of it if your facing the front of the car, there will
be two or three little things that tubes are running into/out of. the three tubes are dashed with white, red,
and one does not have any dashes at all.
(pic boost07)

i tapped into the white one, which was WRONG. so i switched the tubes, and hooked into where the red dashed
tube connected to, and i got a good boost/vac reading from that one.

*when tapping into the hose, its easier just to take the hose off, cut it in the middle, and go from there*

3. i twistie tied the tube for teh boost guage to keep it away from anything hot.

**deadmeat** · 4-1-02, 8:49

back here is where i tapped into the vac hoses to get the readings for the boost guage. there are three tubes back there. a red one, a white one, and one with no markings on it. i tapped into the white one at first, but that was wrong, the RED tube is the one that gives the boost/vac reading.

the three tubes are connected to little boxes on the firewall. i just went in bewteen with the t.

i removed the guage cluster to be able to run the nylon hose for the boost guage.

**deadmeat** · 4-1-02, 8:55

i removed the air vent from the bezel, there are four screws on the back of it. the boost guage just slid right in there, and looks decent

Guage light power:

to get power to your guage for it to light up at night, i used the electric from the cig. lighter.
reasons why i used this: out of the way spot, and its basically usless to me, so if i screw it up, oh well

i just got two wires, one for the ground, and one for the source, and ran those behind the bezel that goes around the guage cluster.

the wire connectors specified in the supply list are for patching the wires into the electric system.

or if you wanna do it the cheap way, a roll of electric tape and a twist on the ends of the wires will do

thats how i did my guage!!!

i do have problems with my guage however. i believe because i used such big nipples for tapping into the boost source, and because with mine i had to use a big adapter (see picture below) i dont always get a constant vac. reading on the guage. it only happens every once in a while, and if i tap the gas, it goes to reading a vac/boost. this is only at idle, and not while driving.

hope this second how to may have helped you out!

happy boosting!

As you may have noticed, i updated this project a little bit, because i provided the wrong information.

the information changed was the tube i tapped into to get my boost reading.

it is, in fact, the red hose that i tapped into for the reading, not the white tube. i apologize to those of you that followed my incorrect directions.
