Features

Vehicle Compatibility and Return Conditions.

This item was designed and engineered in the USA for US domestic vehicles. OBD tools, ECUs, dongles, programmers, and tuners may have limited compatibility with vehicles outside the USA due to regional differences in emission standards and system configurations. Some features and functionality may vary depending on the vehicle and location.

Some electronic tuning devices and programmers require activation, registration, or pairing with a specific vehicle’s VIN (Vehicle Identification Number). Once activated or paired, these devices may become permanently associated with that vehicle, restricting or preventing their use on another vehicle, resticting our ability to offer returns or exchanges.

Please review the product details and images to ensure it meets your needs. For clarification or assistance, feel free to contact a StreetFX agent. Note: Returns are not accepted for special order or tuning products unless the unit is deemed faulty.

Holley in-tank retrofit fuel modules are the easiest way to convert your vehicle's factory tank or fuel cell to an in-tank, EFI fuel system—and gain all the benefits of a Holley Hydramat reservoir, as well. This conversion requires only basic tools, no welding or fabrication. The low-profile, aluminum module design includes a billet pump hanger bracket to control vibration; Holley's innovative clamping system and integrated fuel pump allow you to locate the module anywhere in the tank beside your existing sending unit. Once installed, simply hook up your fuel lines and your power source/ground, and you're ready to roll. Holley in-tank retrofit modules are available with fuel pumps for both return and returnless-style systems—and models to support various liters per hour (LPH).

Additional details:
• Installs in any fuel tank to fit a wide range of applications
• The low-profile design is only 1.275 in. thick above the tank mounting surface for added clearance
• Clamping system allows you to rotate the unit 360 degrees for easier clocking of plumbing and wiring
• Hydramat fuel reservoir's 3 x 15 in. mounting flange has six clocking pin locations for 360 degree adjustment
• Black anodized aluminum construction to resist corrosion
• 1/4 in. NPT ports available for numerous plumbing options
• Ideal for Terminator EFI, Sniper EFI, MSD Atomic EFI, or any TBI or EFI conversion
• Optional rollover valve available
