Do not take out the label and take off the lid as this will lead to the instability of the sensor and manufacturer
could deny warranty. (except cutting of sensor length within the allowed range).
Make sure all the necessary tools are ready before the installation.
CAP10CNR be equipped with screws. We advise customers should use stainless steel rivets to fasten
the plastic flange onto tank for all type of tanks and only using screws for the thick and hard ones.

Discription
Note
1
Remove fuel: Remove all fuel from the tank.
Some tank have been welded with oil filter and have
float level sensor installed, so it is necessary to take
out the float level sensor before removing the fuel.
2
Clean the tank
Must clean the tank thoroughly.
3
Central hole locating: The hole will be in
the center of tank's up-per side or closest to
center.
This is an important step as it will directly affect the
stability of the fuel level data.
4
Drilling the central hole:
After determining the center of the oil
tank, we clean the surface and use a 38
mm drill to make a hole on the oil tank.
Remove any burrs from the drilled hole
by a file.
Before drilling, it is vital to check whether the hole is
affected by the internal metal frame or obstacles at
the bottom the tank.
5
Flange installation:
Place the 4 mm rubber gasket at the
center of the tank's upper side.
Place the plastic flange onto the rubber
gasket (4 mm).
Mark 4 points at the bolt hole.
Use screws /rivets to fasten the 4 mm
rubber gasket and the plastic flange
onto tank.
Only using screws for the thick and hard tanks.
Unplug the screw/ rivet symmetrically.
8. Sensor Installation Guidance

6
Sensor cutting:
After flange installation, we determine the length of the sensor to be installed as picture below:
C = L+20+20-(H+14) => C = L+26-H (mm)
C: Length to be cut.
L: Original length of the sensor.
H: Height of the tank.
*Example:
Sensor length is L = 2000, H = 1700 mm => C = 326 mm => Cut the sensor pipe length of 326 mm.
7
Calibration:
After cutting, make sure the sensor tube is clean.
Re-plug the Filter footer and tighten the screw.
Turn on the sensor in at least 30 seconds in order for the sensor to automatically recognize its
new length.

8
Final:
Place the O-ring on the top of the threads, ensure that it can touch the aluminum housing of the
sensor (as below picture):
Install sensor into the threads of flange and turn it in clockwise direction.
Using the O-ring enables to rotate the sensor within 180 degrees from final tighten position and
assuring that the oil will be not spilled (as below picture):
Use the 2mm Allen key to lock the hex bolt to protect the sensor rotate backwards.
Connect the sensor with the cable.
Use sensor head seal to cover the sensor and then use plastic and then use plastic twister seal
to lock the head seal and connector seal to protect the sensor.
Please follow the below steps:
Note
Step 1: Remove the cover
Step 2: Remove the terminal connector
Step 3: Use the 2 mm Allen key to unlock the hex bolt
Step 4: Turn the sensor in counter-clockwise direction
Do not hold the male connector to rotate sensor
directly, that can make the male connector broken.
Do not use locking pliers, pipe wrenches, etc. to
twist the sensor as this cause damages the
structure of the sensor such as cast aluminium
housing, label, signal cables (connector), circuit
board, ect. and it will not be covered under
warranty.
