Stay Ahead Of Problems Before They Leave You Stranded

If you're running a 2003–2017 Dodge RAM 2500 or 3500 with a Cummins under the hood, the PPE Fuel Rail Pressure Gauge is one of those upgrades that pays for itself in peace of mind. Low fuel pressure can sneak up on you, leading to poor performance, sluggish throttle response, or even injector and pump damage. This gauge gives you a clear look at what's going on inside your fuel system before warning lights start flashing or problems get expensive. Whether you're tuned for more power or just want better visibility into your truck’s health, this gauge keeps you in control. It's easy to read, reacts quickly, and lets you spot trouble as it's developing, not after it ruins your day. Pair it with the optional PPE 9-foot harness for a simple install and even cleaner wiring. It's a small investment with a big return, especially for anyone who tows, hauls, or drives their Cummins hard.

Real Time Data That Helps Diagnose Fuel System Health

The PPE 513010000 Fuel Rail Pressure Gauge is a diagnostic tool designed to give Dodge RAM 2500 and 3500 owners accurate, real-time visibility into fuel system pressure from 2003 through 2017 model years. By reading fuel rail pressure directly, this gauge can reveal early signs of CP3 pump wear, injector issues, or supply restrictions that would otherwise go unnoticed until performance suffers. Monitoring fuel pressure is especially critical for modified engines or those with upgraded injectors and tuning, where fuel demands increase. When pressure drops below optimal levels, you’ll know immediately and can take action before further damage occurs. The gauge works with or without the optional PPE 9-foot harness, which simplifies installation but is not required for operation. It's an essential piece of equipment for anyone wanting to maintain precise control over fuel delivery and avoid costly repairs. Whether you're troubleshooting a power loss or tuning for maximum efficiency, this gauge gives you the information you need to protect your engine and optimize performance.

Fits: 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017 Dodge RAM 2500/3500

Notes:

• Designed for 2003–2017 Dodge RAM 2500/3500 with 6.7L or 5.9L Cummins engines.
• Helps detect fuel pressure drops before performance issues arise.
• Low rail pressure can indicate problems with injectors, fuel pump, or filtration system.
• Recommended for tuned or modified diesel engines running increased fueling demands.
