The Arrington Performance Billet Fuel Hat has been tested for use in 5.7 and 6.1 HEMI applications up to 700 RWHP. Beyond that level of power you will need our triple fuel hat which will be released soon.

This kit comes with everything needed to add a Walbro 255 lph style 340 fuel pump to your Mopar fuel system, while retaining your stock fuel pump and fuel basket. Thus, your vehicle gets all the benefit of the stock pump pressure, while adding the additional performance of a Walbro 255 number 340. By utilizing the best components of the original OEM fuel assembly and improving on its weaknesses the Arrington kit maintains a high level of efficiency, allowing the system to safely maintain pressure on cars up to 700 RWHP.
