Fuel Pressure Regulator: Ls1tech Mounting Location Guide

LS1TECH is a Camaro and Firebird forum where users can discuss a range of topics, including fuel pressure regulator mounting. The placement of the fuel pressure regulator depends on the engine's horsepower. For stock or mild horsepower engines, the regulator can be mounted towards the rear of the car, while for high horsepower engines, it should be placed closer to the engine to maintain proper pressure. Some users have shared their experiences mounting the regulator in different locations, such as on the frame rail, the cylinder head, the body above the axle, or the inner fender panel. It is also important to consider the type of fuel pressure regulator and the necessary fittings and adapters for a secure installation.

Mounting the regulator on the ICT billet valley cover

• Ensure you have the necessary tools and equipment, including a drill and tap set, as well as the ICT billet valley cover and the fuel pressure regulator.
• Measure the ICT billet valley cover to determine the appropriate location for drilling and tapping. Mark the mounting points accordingly.
• Drill and tap the ICT billet valley cover at the marked points. Take your time and use appropriate lubrication to ensure the best results.
• With the ICT billet valley cover drilled and tapped, you can now mount the fuel pressure regulator. Secure it firmly in place, following the manufacturer's instructions.
• Once the regulator is mounted, it is important to check your work. Ensure that the regulator is secure and properly fitted.
• After confirming that the regulator is mounted correctly, you can proceed with any necessary post-installation steps, such as connecting the fuel lines and testing the system.

It is worth noting that some users have suggested that the regulator can be installed upside down if needed, and it will still function effectively. This provides some flexibility in mounting options. Always refer to the instructions and recommendations provided by the manufacturer for the best results.

Installing a Deluxe LS Swap Fuel Filter/Regulator

Installing Speedway's Deluxe LS Swap Fuel Filter/Regulator is a quick and easy process, as demonstrated by Josh and Joe in their installation video. Here is a step-by-step guide on how to install the Deluxe LS Swap Fuel Filter/Regulator:

Step 1: Prepare the Vehicle

Josh and Joe are working on a 1952 Chevy truck, adapting an LS motor into an older chassis. They highlight the benefits of the Deluxe LS Swap Fuel Filter/Regulator, which is an upgrade on their original part. The new design removes potential leak points by eliminating the need for adapters.

Step 2: Understand the System

Josh explains that the EFI AN6 filter and regulator is similar to the system used in Corvettes, featuring a returnless style system. This means that the return line runs directly back to the tank, reducing the amount of hose required. The regulator is set at 58 PSI, which is ideal for LS swaps.

Step 3: Remove the Old System

Joe points out the old system, which includes a GM plastic quick-connect and an adapter fitting. This setup is more complex and has more potential leak points.

Step 4: Install the New Filter/Regulator

Josh and Joe put the new filter/regulator in the same spot as the old one, using the same lines and lengths. This ensures that it will mount easily and function correctly.

Step 5: Check the Fittings

Josh emphasizes the importance of not overtightening the fittings. He recommends making them snug, pressurizing the system to check for leaks, and then tightening any problem fittings as needed. This prevents damaging the fittings or threads.

Step 6: Finalize the Installation

After the new filter/regulator is installed, the system is primed and checked for leaks. Joe and Josh emphasize the simplicity of the process, highlighting that it took only about five minutes to complete. They also mention that Speedway Motors offers a wide range of parts for LS swap projects.

The Deluxe LS Swap Fuel Filter/Regulator simplifies the fuel system, reducing potential leak points and making it ideal for LS swap projects.

Placing the regulator on the driver's side

When placing the regulator on the driver's side, there are a few things to consider. Firstly, the fuel system you are working with and the location of the factory feed. It is recommended to bolt the regulator with the fuel rail if possible.

For high-horsepower engines (above an estimated 400hp), it is advisable to mount the regulator closer to the engine to ensure adequate pressure at the rail. This typically means placing it on the frame in front of the gas tank, approximately three feet away. It is also suggested to include a heat shield between the fuel lines and the muffler.

For stock or mildly modified engines, mounting the regulator towards the rear of the car is acceptable. This can help keep things simple and minimise the length of fuel lines needed, resulting in a cleaner look.

When deciding on a location, consider the distance between the regulator and the engine, as well as any potential heat sources nearby. It is also important to note that the orientation of the regulator does not affect its function, so you have flexibility in how you position it.

Using the factory Evap line as a return line

Another user provides a detailed description of their setup, which includes using all Aeromotive quick disconnects and -6AN braided lines for the return. They also used a -8AN stainless braided line and 3/8" quick disconnects for the feed side. This user spent a bit more than $50 on their setup, with each Aeromotive quick disconnect costing between $35-40.

It is important to note that some people recommend leaving the EVAP intact as it is a vital part of the tank's operation.

When installing a fuel pressure regulator, it is recommended to make the fittings snug, pressurize the system to check for leaks, and then tighten any problem fittings. This avoids overtightening and reduces the risk of ruining fittings or damaging threads.
