Holley 255 LPH In-Tank Retrofit Carbureted Fuel Pump Module For Returnless EFI Fuel Systems.

If you want to keep your classic Mustang as original as possible, upgrade your factory fuel pump with an aftermarket carburetor fuel pump. CJ Pony Parts offers the Holley 255 LPH In-Tank Retrofit Carbureted Fuel Pump Module 12-129 For Returnless EFI Fuel Systems. Convert your fuel system with an in-tank low profile feature with an easy integrated fuel pump and clamp unit.

Features and Benefits:
- In-Tank Carburetor System Conversion
- 6-1/2" to 12" Depth Install
- Low-Profile 1.275" Thick Design
- Sits Above the Tank Mounting Surface
- Innovative 360-Degree rotation Clamping System
- Die Cast Aluminum Construction
- 1/4" NPT Port Plumbing Options
- 255LPH Pump Rate

Made especially for carbureted units, Holley has designed their latest retrofit pump module similarly to the existing EFI pump modules using a 255 LPH pump. Unlike the EFI, this module includes a built-in regulator for lower fuel pressure that carburetor applications require. Now you can convert your factory tank or fuel cell to an in-tank fuel system with basic tools that require no welding or fabrication. The aluminum module design includes a die cast pump hanger bracket to control pump vibration while also providing a low profile design for a premium fit where space is limited. Hook up your fuel lines and power source with Holley's innovative clamping system and integrated fuel pump, and if you change your mind later then simply upgrade this module to an EFI system by changing the internal regulator.
