FAQ

Does this kit replace my factory in-tank lift pump?

Yes. The included Fuel Module Upgrade Kit pulls fuel through a 1/2" bulkhead fitting and feeds the CP3 via the externally mounted Raptor 4G pump.

What fuel pressure is it set to from the factory?

Raptor 4G systems for this application are typically preset around 15–17 PSI and are adjustable. Always verify pressure after installation.

Do I need a return line?

No—this pump is internally regulated, so no return line is required.

Is 100 GPH enough for performance tuning?

For stock to mild builds, 100 GPH is ideal. For larger injectors/tuning, consider the 150 GPH system listed above.
