FAQ
Does the R4SBD053 require a return line?
No. Raptor-4G pumps are internally regulated and feed the factory fuel filter housing without a return line.
What trucks does this cover?
2004.5–2007 Ram 2500/3500 5.9L common-rail and 2007.5–2018 Ram 2500/3500 6.7L Cummins.
What pressure is it set to from the factory?
Approximately 15–17 PSI for stock applications; the regulator allows adjustment for specific builds as needed. Always verify with a gauge.
How does this compare to the RP-4G-100?
The RP-4G-150 (R4SBD053) flows ~150 GPH for higher demand than the RP-4G-100 (R4SBD050), which is aimed at stock to lightly modified trucks.
Is a module upgrade or bulkhead fitting used?
Yes—this system uses a fuel module upgrade to pull through a 1/2" bulkhead fitting and bypass the factory in-tank lift pump on these applications.
