Dodge Challenger Hellcat SRT8 Fuel Tank Gas Pump

inventory at Buy Mustang parts Ltd, dealing with Hellcat fuel systems requires extreme precision. While “SRT8” generally refers to the 2008–2014 6.1L or 6.4L models, the Hellcat (2015–2023) is a vastly different beast. Its fuel system is a high-pressure, high-volume setup designed to keep a 700+ HP supercharged engine from running lean.

1. Technical Identification: Hellcat vs. Standard SRT

The Hellcat fuel tank and pump are specialized. Unlike a standard Challenger, the Hellcat utilizes a dual-pump (or even triple in newer HO models) high-flow module to handle the massive fuel demand under boost.

2. The “Dual Pump” Market Value

A genuine Hellcat fuel pump is a “holy grail” part for owners of 5.7L or 6.4L Challengers looking to do a supercharger conversion. Because the standard pumps can’t keep up with boost, they look specifically for Hellcat “Take-offs.”

• OEM Hellcat Pump (Used): $650 – $850 (depending on the revision code).

• OEM Hellcat Pump (New): $1,050 – $1,600.

• Fuel Tank (Used): $400 – $600 (shipping is the biggest cost due to size).

3. Inventory Check: SRT8 (Early) vs. Hellcat (Late)

• 2008–2014 SRT8: These use a simpler, lower-pressure pump system. If you have a pump from an older 6.1L SRT8, it is not suitable for a Hellcat engine.

• 2015+ Hellcat: These modules feature a much larger electrical connector and a high-flow “jet pump” on the passenger side to transfer fuel across the “saddle” of the tank.

4. Strategic Advice for Buy Mustang parts Ltd

• The “Jailbreak/Redeye” Upgrade: If you source a pump from a Redeye or Super Stock, it is even more valuable. These units have different flow rates and can sell for a premium to standard Hellcat owners looking for an OEM upgrade.

• The “Seal & Ring” Professionalism: Never ship a fuel pump without the Mopar Fuel Tank Seal (#4809783AA). In your luxury descriptions, mention: “Includes a fresh Mopar seal and locking ring for a leak-free, professional installation.”

• The “Saddle” Tank Warning: Dodge fuel tanks are “saddle” shaped to clear the driveshaft. When selling a tank, verify the Internal Transfer Lines are intact. If they are snapped or clogged, the car will run out of gas while the gauge still shows half a tank.
