TABLE OF CONTENTS
• All Ford original owner information supplied by Ford must remain with the vehicle.
• Compressed natural gas is a combustible fuel, ammable and highly explosive.
• CNG is stored under high pressure (normal working pressure of 3,600 psi) at 70ºF (21ºC).
• Tampering with or improperly maintaining the high pressure fuel system can result in fatality or serious injury.
• All CNG and gasoline maintenance must be performed at an authorized service center with qualied technicians.
• Use extreme caution and follow all related safety guidelines. We have tried to make this installation as safe as possible but we can not predict all scenarios.
• This CNG system requires gasoline in vehicle at all time–ate on CNG. When the low gasoline level indicator light illuminates the CNG system will automatically turn off until additional
gasoline is fueled into the vehicle and the low level light turns off. This is required by Ford to protect the engine from damage.
NOTE: Disconnect the vehicle battery before install (Refer to page 5). This includes partial install, servicing, and or maintenance.
!! WARNING !! Follow instructions as directed in the installation manual and do not attempt shortcuts.
Follow proper safety procedures. Failure to do so can lead to bodily harm or fatality. Tampering with or
improperly maintaining the high pressure fuel system can also result in bodily harm or fatality.
!! WARNING !! Batteries normally produce explosive gas. Therefore, do not allow ames, sparks or lighted
substances to come near the battery. When charging or working near a battery, always shield your face and
protect your eyes. Always provide ventilation. Failure to follow these instructions may result in personal injury.
!! CAUTION !! Be aware that this installation requires the use of High Pressure, Flammable, and Highly
Explosive compressed natural gas. CNG is stored under at maximum of 3,600 psi and at 70ºF (21ºC).
!! CAUTION !! Failure to complete the pre-installation checklist may result in severe engine damage after
installation is complete.
!! CAUTION !! This installation is intended for unmodied vehicles. If the vehicle has been modied, consult
ALTECH-ECO before the beginning install.
DISCLAIMER
ALTECH-ECO assumes no responsibility for damages occurring from accident, misuse, abuse, improper
installation, Improper operation, and lack of reasonable care or all previously stated reasons resulting in
incompatibility with other Manufacturer’s products.
Chemicals and Lubricants:
1. Silicone lubricant spray is required on all o-rings on ttings.
2. Epoxy primer or equivalent to rust proof any exposed metal.
3. Ford approved coolant liquid to top off the reservoir.

Attaching Accessories to Aluminum Panels and Structure
Models Affected: 2015 MY and later F-150
Background:
The high-strength aluminum alloy in the all-new F-150 does not produce red rust like steel. We have gone to great lengths
to develop coatings to inhibit corrosion. However, customers should take note that when installing aftermarket equipment,
aluminum can still corrode if the aluminum is attached to dissimilar metals. This type of corrosion is called “galvanic
corrosion” and it occurs where there is contact between different metals, like steel or stainless steel fasteners.
Protecting against galvanic corrosion
When installing aftermarket equipment, it is necessary that the installer pay special attention when drilling or clamping
dissimilar metals to the aluminum body.
• Anytime the factory paint is damaged, it is recommended that the paint be repaired with a suitable coating prior to
installing aftermarket equipment (i.e. splash guards, bug shields, tool boxes, etc.)
• When installing fasteners into the mounting hole the fastener should not have contact or have an interference fit
with the sheet metal
• For zinc coated steel bolts and screws, an aluminum washer should be used
• For further protection, an isolation layer should be used between the two dissimilar metals
• When clamping onto the truck, a polypropylene or urethane tape can be used as the isolating layer
Paint, Isolator, and Fastener Recommendations
We have tested many combinations of fasteners and coatings that are widely used in the aftermarket and have provided a
list of approved products to help ensure durability, strength and quality.
** For small repair of factory paints around mounting hole. Follow manufacturer’s directions for use.

In this section we illustrate some best practices to isolate steel from coming in contact with aluminum. Using the
previously listed fasteners and coatings in addition to good isolation techniques will help ensure durability, strength and
quality of your F150.
Note: The following illustrations are not vehicle specific and are intended for reference only.

DISCONNECT THE BATTERY
DISCONNECT THE GASOLINE FUEL PUMP
Gasoline system pressure release:
1. With the vehicle in NEUTRAL, position the truck on the hoist.
2. NOTE: The Fuel Pump Control Module is located on the frame rail above the fuel tank.
3. Disconnect the fuel pump control module electrical connector.
4. Start the engine and allow it to idle until it stalls.
5. After the engine stalls, crank the engine for approximately 5 seconds to make sure the fuel rail pressure has been released.
6. Turn the ignition switch to the OFF position.
7. When the CNG system installation is complete, reconnect the fuel pump control module electrical connector.
8. Cycle the ignition key and wait 3 seconds to pressurize the fuel system.
9. Start the engine and check for leaks.
- Have original Ford vehicle manuals available for additional instructions if needed.
NOTE: Some steps are repeated from section to section, follow instruction until each
of the repeated steps are complete and ignore that step for other sections.
Disconnect the battery:
1. Loosen the nut on negative terminal wire and slid battery wire up and off of post. Place to side.
2. Place a plastic cap on negative terminal post to protect from accidental contact.
