The Raptor 4G replaces that weak link with a lift pump engineered to deliver a steady, dependable fuel supply to the engine. With 100 GPH and 150 GPH options, you can choose the right fuel delivery rate for your build, whether you're maintaining a stock daily driver or supporting a truck with upgrades. Application-specific versions are available for trucks with either the original block-mounted pump or an in-tank pump, making it important to verify your existing configuration before ordering.\u003c\/p\u003e\n\u003cp\u003eThe Raptor 4G uses a high-end Gerotor pump with PureFlow 4G technology and an advanced adjustable regulator for accurate fuel-pressure control. The system is preset to 15–17 PSI, requires no dedicated return line, and includes a no-drill mounting bracket, wiring harness, and 1\/2-inch Big Line fuel lines for a straightforward installation. The R4SBD324 provides 100 GPH for trucks without an in-tank fuel pump and supports stock to approximately 500 rear-wheel horsepower, while the R4SBD356 provides 100 GPH for trucks equipped with an in-tank pump. For higher-output builds, the R4SBD325 increases capacity to 150 GPH and supports approximately 500–800 rear-wheel horsepower.\u003c\/p\u003e\n\u003ch2\u003eWhich Flow Rate should you choose?\u003c\/h2\u003e\n\u003cp\u003eWhen it comes to upgrading your fuel system, choosing the right GPH (gallons per hour) rating isn’t about picking the biggest number; it’s about matching your pump to your truck’s real-world demands. But choosing between 100 and 150 GPH? That’s where a lot of people get stuck.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e100 GPH: Stock Reliability Upgrade (STOCK-500 HP)\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePerfect for stock trucks or very mild setups.

However, if it ever failed and had been replaced previously, it was very likely retrofitted with the newer design that actually placed the pump in the fuel tank. If you're not sure where your pump is located, simply \"bump\" the key to engage the pump, then listen to see whether the pump's hum comes from the engine compartment or the fuel tank.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AirDog | PureFlow Technologies","offers":[{"title":"Without in Tank Fuel Pump \/ 100 GPH","offer_id":53760579830125,"sku":"PF-R4SBD324","price":579.0,"currency_code":"USD","in_stock":true},{"title":"Without in Tank Fuel Pump \/ 150 GPH","offer_id":53760579862893,"sku":"PF-R4SBD325","price":620.0,"currency_code":"USD","in_stock":true},{"title":"With In Tank Fuel Pump \/ 100 GPH","offer_id":53760579895661,"sku":"PF-R4SBD356","price":606.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0892\/2487\/2301\/files\/F198644967.jpg?v=1787072316","url":"https:\/\/dieselpowerproducts.com\/products\/airdog-raptor-4g-fuel-pump-03-04-ram-5-9l-cummins","provider":"Diesel Power Products","version":"1.0","type":"link"}
