DIRECT PORT (NOZZLE SYSTEM) INSTRUCTIONS

Congratulations on the purchase of your Nitrous Express Direct Port system. Nitrous Express utilizes only the highest quality components

designed for the use of liquid nitrous oxide. To properly utilize these specially designed components and obtain the trouble-free operation that

this system is capable of producing, it is extremely important that you read all instructions carefully. Pay special attention to the important notes

at the end of the installation steps and the tuning tips listed at the back of this instruction sheet.

The installation procedures are divided into 5

sec

tions. Please pay particular attention to each

one:

1. Mounting the

bottle.

2. Drilling the manifold & plumbing the

nozzles

3. Plumbing the fuel

system.

4. Wiring the

system

5. Testing the

system.

Before starting any installation

steps:

1. Disconnect the negative battery

terminal.

2. Never use Teflon tape on any system fittings.

Tape

debris will cause numerous problems

ranging

from clogged solenoids to

blocked jets. Use the

red

liquid NX thread sealer supplied with the

system.

A drop is all it

takes.

3. Have your nitrous bottle filled by a reliable

source,

being sure it is filled to capacity with filtered “Nytrous +” nitrous oxide. For filling

MOUNTING THE

BOTTLE

The nitrous bottle should be mounted in the

trunk

area or outside of the passenger compartment. If

this

is not possible or practical a

NHRA approved blow

down tube and vent fitting (PN’s 11708, 11709)

must

be installed. The positioning of the bottle should

shown in illustration “A”. This will allow the

siphon

tube to be covered at all

times.

The mounting brackets should be assembled

the bottle with the short bracket approx. 2” from

the

bottom, on 10 lb. bottles the long

bracket should

place approx. 7” above the lower one, on 15lb

bottles

the upper bracket should be approx. 12” above the

lower

bracket. Use this mock up as a template to

locate the four mounting bolt holes.

Note:

Before

drilling holes be sure to check for clearance

beneath

the mounting surface i.e.: fuel tank, fuel lines,

brake lines.
