Auto Meter 4511 - Manual (Page 3)

wARNINg: Use Teflon tape or sealant only where indicated.
Do not use oil on threads.
wARNINg: This gauge is supplied with a special restrictor fitting that
Must be installed on the braided line leading to the
nitrous gauge.
wARNINg: USE ONLY -4AN high pressure stainless steel braided
line when installing this gauge. All fittings must have a
minimum working pressure of 2000 psi.
1. If you are not familiar with nitrous oxide systems and their
installations do not install this gauge. Have a qualified
mechanic install it for you.
2. Determine where the nitrous gauge will be mounted and the source
of the pressure (bottle outlet or nitrous solenoid inlet fitting). Then
determine the length of steel braided line required.
(Auto Meter offers three -4AN stainless steel braided line kits: Model
#3227- 3 feet, Model #3228- 6 feet, Model #3229- 4 feet)
3. Secure the -4AN stainless steel braided line to the back of the
gauge as shown in the illustration.
4. Install gauge in appropriately sized dashboard hole or use under dash
panels. Secure gauge with the mounting bracket provided. NOTE: If
alternate gauge mounting is used other than in-dash or under dash,
mounting provisions may have to be determined by the installer.
5. Make sure the nitrous bottle valve is closed.
6. Secure an in-line gauge adapter (eg. NOS part #16770 or #16771)
in a vice. Install the special restrictor fitting (supplied with gauge) in
the in-line gauge adapter. Do not over tighten as this may result in
stripped threads or a broken fitting.
7. Remove the main nitrous feed line from the bottle or the nitrous
solenoid. Install the in-line gauge adapter with the special restrictor
fitting either on the nitrous bottle or nitrous solenoid. Re-install the
main nitrous feed line. Install the braided line from the nitrous gauge
to the restrictor fitting.
8. Open the nitrous bottle valve.
NOTE: Test all fittings and hoses for any leakage. If any leaks are
detected, determine the cause of the leak and repair. Do not operate
vehicle if any leaks are detected.

1. If you are not familiar with proper brake system bleeding
procedure, do not install this gauge. Have a qualified mechanic do
it for you.
2. Install gauge in appropriately sized dashboard hole or use under dash
panels. Secure gauge with the mounting bracket provided. NOTE: If
alternate gauge mounting is used other than in-dash or under dash,
mounting provisions may have to be determined by the installer.
3. Secure bleed screw, bleed screw bushing, and brake line fitting to the
tee provided with the gauge as shown above.
4. Secure the tee assembly from Step 3 to the gauge port. Be sure not to
over tighten as this can cause the movement to loosen in the case.
5. Install a tee at the brake system location suitable for your application.
6. Install steel double flare brake line between gauge and tee.
7. Connect WHITE light wire to the dash lighting circuit or other 12V
source. Connect the BLACK light wire to a suitable ground. (which
applicable)
8. Bleed your gauge and brake system using standard brake bleeding
procedure. If you are not familiar with brake bleeding procedure,
have a qualified mechanic install this gauge for you.
