Description

Holley Sniper in-tank fuel pump modules are direct-fit units to drop directly into the specific vehicle application. Two modules--the Sniper 340 lph and Holley 525 lph--feature a 6061 T-6 flange that has a bright dip black anodized finish for corrosion protection and long-lasting good looks. The flanges have a 6AN O-ring outlet and return port making the plumbing connections easy. The assembled modules include a new filter sock and the lock ring to complete the installation into your stock fuel tank. Choose the module designed for your vehicle.

Notes:

* Includes a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for the specific application
* 340 lph module supports up to 700 EFI or 900 hp carbureted
* 525 lph module supports up to 1,200 EFI or 1,450 hp carbureted
* Both EFI and carbureted systems will need a bypass design regulator
