Installation Manual v1.1:
High Performance Fuel System Stage 2
Ford 6.0L Power Stroke
Please read all instructions before installation.
Thank you for purchasing the ATS High Performance Fuel System for the Ford 6.0L Power
Stroke. This manual is to assist you with your installation of the system. If you are installing
this system for a customer, please pass this manual on to your customer for future reference.
This installation, while not complicated, is time consuming. Some steps can be difficult due to
the position of some components in the engine compartment. Please read through all the
instructions before starting work, and if you are not comfortable with the install, have a qualified
technician do it.
1. Begin with Stage 1 instructions until directed to this manual.
2. Raise the pickup and support it with jack stands or hoist that are rated to safely support
the weight.
3. Remove the retaining bolts that hold the exhaust manifolds to the driver’s side turbo uppipe. Bolts can be stubborn to remove and may require replacement to complete
procedure. Passenger side turbo up-pipe should not need removing; however, we
recommend that you remove the down-pipe for easier installation.
4. Carefully move the up-pipe away from the cylinder head just enough to allow access to
fuel plugs. Caution: DO NOT damage the up-pipe by moving too far. If at any
point you feel that the up-pipe will not move away further and you cannot perform
installation, then removal of the clamps at turbocharger turbine inlet and Exhaust
Gas Recirculation (EGR) cooler inlet, and retaining bolts to up-pipe on passenger
side will be required to finish installation.
5. Using a 6mm hex wrench, remove the plug from the rear of the cylinder head on both
driver and passenger side. Caution: Fuel may leak from the plugs.

6. Route hard fuel line B to formerly plugged hole in the driver side rear cylinder head,
direct it through the locating tabs on cylinder head (shown in photo on page 3), insert and
tighten the banjo bolt with washers (torque banjo bolt to 28 ft-lbs). Keep line away from
heat shields; make slight adjustments to the hard fuel line if necessary. Do not kink the
line and ensure line is not in contact with any components.
7. Route hard fuel line C to formerly plugged hole in the passenger side rear cylinder head,
direct it through the locating tabs on cylinder head (shown in photo on page 3), insert and
tighten the banjo bolt with washers (torque banjo bolt to 28 ft-lbs). Keep line away from
heat shields; make slight adjustments to the hard fuel line if necessary. Do not kink the
line and ensure line is not in contact with any components.
8. Reinstall turbo up-pipe bolts and tighten at this time (torque up-pipe bolts to 20 ft-lbs).
Reinstall clamps at turbocharger turbine inlet and EGR cooler inlet and reinstall
downpipe if removed.
9. Lower the vehicle.
10. Remove the Fuel Injection Control Module (FICM) on the driver’s side of the engine
may ease installation.
11. Put D (45 degree fitting) on hard line B (from the back of the driver side cylinder head).
12. Install the 35” -4 braided line into D, and tighten.
13. Route braided line toward back of Regulator Assembly as shown.
14. Reinstall the FICM if previously removed.
15. Put a second fitting D on hard line C (from the back of the passenger side cylinder head).
16. Install the 30” -4 braided line into C, and tighten.
17. Route braided line toward front of Regulator Assembly as shown.

18. Assemble Regulator with fittings E, F, G, and H and mounting plate as shown.
19. Remove the two passenger side Alternator attaching bolts and position Regulator
Assembly atop Alternator. Do not mount Regulator Assembly at this time, you will want
some play when you route the lines.
20. Attach the 35” braided line (from the back of the driver side cylinder head) to the 45°
fitting F at the back of the regulator. Make sure the line is positioned properly before
tightening.
21. Attach the 30” braided line (from the back of the passenger side cylinder head) to the 90°
fitting H at the front of the regulator. Make sure the line is positioned properly before
tightening.

28. If you have purchased the stage 3 fuel kit then proceed to those instructions at this
time.
29. Reinstall the air box.
30. Reinstall the intercooler pipes.
31. Reconnect the negative battery cables.
32. Start the truck. Check for any fuel leaks. Using a fuel pressure gauge adjust pressure to
50 psi at idle. For more performance, pressure adjustment can be set up to 70 psi at idle.*
To adjust pressure loosen locknut on regulator and turn clockwise to raise pressure and
counter-clockwise to lower pressure.
*The 70 psi setting will ensure maximum fuel supply from the stock pump to the cylinder heads
under high demand conditions. The down side of this is more wear and tear on the stock pump
due to constantly having to maintain the higher idle fuel pressure setting. An ATS Stage 3 kit
(with an Aeromotive Marine Grade Extreme Duty Fuel Pump) will supply all fuel demand
without needing an excessively high idle fuel pressure setting.
We strive to make our instructions as clear and complete as possible. To achieve this, our
instructions are under constant construction. We encourage you to visit our Technical Support
Website (http://www.atsdiesel.com/ATSWebsite/Technical.asp) to check for the most up-todate manuals and diagrams as well as other information. If you have any suggestions as to
how we can improve this installation manual, let us know at Suggestions@ATSDiesel.com
