We’ll cover everything from pre-installation preparations to final checks, ensuring a smooth and successful installation.
1. Pre-Installation Preparations: Gathering Tools and Parts
Before diving into the installation, thorough preparation is paramount. This involves gathering all the necessary tools and components, ensuring you have a safe and organized workspace. A 5.9 Cummins FASS Fuel System install requires meticulous attention to detail.
Essential Tools:
- Socket wrench set (metric and SAE)
- Wrenches (various sizes)
- Screwdrivers (Phillips and flathead)
- Pliers (needle-nose and slip-joint)
- Torque wrench
- Fuel line disconnect tools
- Ratchet and extensions
- Safety glasses
- Gloves
Necessary Components:
- FASS Fuel System Kit (ensure compatibility with your specific 5.9 Cummins) – Check the FASS website (https://fassfuelsystems.com/) for the correct model.
- New fuel lines (appropriate size and length)
- Fuel filter wrench
- Mounting hardware (brackets, bolts, etc., often included with the kit)
2. Fuel Tank Preparation and Drain
Safely draining the fuel tank is crucial to minimize spillage and ensure a clean installation. Improper handling of diesel fuel can be hazardous, so observe all safety precautions.
Steps:
- Locate the fuel tank drain valve.
- Position a suitable container (large enough to hold the entire tank’s contents) beneath the drain valve.
- Carefully open the drain valve, allowing the fuel to drain completely.
- Once drained, close the valve securely.
3. Removing the Existing Fuel System Components
This step involves carefully disconnecting and removing the existing fuel lines and components that will be replaced by the FASS system. Take photos before disassembling anything to assist with reassembly.
Key Components to Remove:
- Existing fuel filter
- Fuel pump
- Existing fuel lines
4. Installing the FASS Fuel System Pump and Filter
The heart of the FASS system is the high-flow fuel pump and its integrated filter. Correctly positioning and securing these components according to the manufacturer’s instructions is essential for optimal performance and longevity. Refer to FASS’s installation manual ([insert link to example manual if available]).
Mounting Considerations:
- Securely mount the pump and filter to a stable location, ensuring proper clearance for all components.
- Use provided mounting brackets and hardware for proper support.
- Consider vibration dampeners for reduced noise and increased longevity.
5. Connecting Fuel Lines and Wiring
Connecting the fuel lines and wiring requires precision. Ensure that all connections are tight and free of leaks. Incorrect connections can lead to fuel leaks, which need to be addressed immediately.
Fuel Line Connections:
- Use the correct size fuel lines and clamps.
- Ensure all connections are secure and free of leaks.
- Double-check all connections before starting the engine.
Wiring Connections:
- Follow the wiring diagram included with your FASS kit precisely.
- Properly connect power and ground wires.
- Ensure all connections are secure and well-insulated.
6. Testing and Leak Checks
Before starting the engine, thoroughly inspect all connections for leaks. This is an absolutely crucial step.
Leak Check Procedure:
- Visually inspect all fuel line connections.
- Use a soapy water solution to check for air bubbles, indicative of leaks.
- Tighten any loose connections.
- Perform a pressure test if possible.
7. Bleeding the Fuel System and Initial Startup
After the installation, the fuel system needs to be bled to remove any air pockets. This ensures proper fuel flow to the engine.
Bleeding Procedure:
- Consult your FASS system’s specific instructions for the correct bleeding procedure.
- Manually prime the pump if necessary.
- Crank the engine for several seconds, then allow it to run.
- Check for any leaks.
8. Final Checks and Post-Installation Drive
Once the engine is running smoothly and all leaks have been addressed, take your vehicle for a test drive to confirm the proper functioning of the new FASS system.
FAQ:
Q1: Will installing a FASS fuel system void my warranty?
A1: This is highly dependent on your vehicle’s warranty terms and the installer. While it might not directly void the warranty, it could complicate warranty claims related to fuel delivery issues if the installation is faulty.
Q2: How often should I replace the FASS fuel system filter?
A2: Consult your FASS system’s manual for the recommended replacement interval. Frequency depends on fuel quality and usage.
Q3: Is professional installation recommended?
A3: While DIY installation is achievable with this guide, professional installation by a qualified mechanic experienced with diesel fuel systems is always an option.
Q4: What are the benefits of a FASS fuel system?
A4: Increased fuel flow, improved fuel filtration, reduced strain on the stock fuel pump, and potentially increased engine performance and lifespan are all possible benefits.
