Meet the BMP 2013–2024 6.7 Cummins Dual Rear Cat Kit

Shipping lead time: 2–3 weeks

If you own a 2013–2024 Ram 6.7L Cummins, you know the factory fuel filtration setup can be… less than fun to service. The Black Market Performance 13–24 6.7 Cummins Dual Rear Cat Kit fixes that by relocating your filtration to the rear, replacing the stock rear fuel/water separator with dual Cat-style filters, and deleting the engine-mounted filter. The result? Faster, cleaner filter changes, lower long-term maintenance costs, and a tidy engine bay—without sacrificing cold-weather performance or water-in-fuel protection.

Why switch to a dual rear Cat setup?

• Easy, mess-free service: Both primary and secondary filters live underneath the truck for quick access—no more reaching down past hot engine components.

• Lower filter costs: Run widely available Cat or other major-brand filters instead of pricey OE units.

• Cleaner engine bay: The billet factory fuel bowl delete removes the engine-mounted filter and reduces clutter under the hood.

• Keep factory safeguards: Your rear fuel heater (heater included) and WIF (Water-In-Fuel) sensors are retained—one in the rear lower location and one in the front via the billet fuel bowl delete—so you keep the functionality you rely on.

What’s included in the kit

• Billet Housing

• Billet WIF Filter Puck

• Factory Fuel Bowl Delete (retains front HEATER and WIF Sensor)

• 2 Cat Fuel Filters

• Fuel Heater ×2

• Extension Harness

• Housing Spacers (only needed for trucks using the factory exhaust hanger)

How it works

BMP’s conversion moves both stages of filtration to the rear frame area and eliminates the engine-mounted canister. With the included billet components, you retain your heaters and WIF sensors in their proper roles—helping support cold starts and alerting you to water contamination—while gaining wide-open access for routine service.

Fitment

Installation at a glance

5. Plug in the extension harness, connect lines, verify routing/clearance, and prime the system.

(If you’re not comfortable working with fuel systems, we recommend professional installation.)

FAQs

Will this throw any warnings?
The kit retains your WIF sensors and heaters front and rear as designed. Always confirm connectors are fully seated and seals are intact during install.

Do the filters come with the kit?
Yes—two Cat fuel filters are included. You can source compatible replacements from Cat or other major brands going forward.

Do I need tuning?
No tuning is required for this filtration conversion.

Why dual filters instead of one?
Dual-stage filtration helps protect modern high-pressure fuel systems while keeping service simple and affordable.
