Race German has devoted themselves to providing quality products for late model BMWs that cover both street and track applications. Race German has now grown their catalog to a wide variety of models and products geared towards keeping your car looking and running nice. Finding a way to measure your fuel pressure is not always the easiest thing to do. Race German wanted to make your life just a little easier with this in-line fuel pressure adapter. This simple solution allows you to splice into your rubber fuel feed line hose and attach a 1/8NPT pressure sender. This would be great to run a fuel pressure gauge, or give you a way to temporarily test your pressure for troubleshooting issues, either way you can't go wrong. *Does not include pressure sender.

Introducing the Vader Solutions Fuel System Upgrade for S58 powered M2, M3, and M4's and G-Chassis B58 models. This uses the same design and engineering that went into developing our popular A90 Supra Fuel System Upgrade. This kit is the best solution in terms of fueling, no additional fuel lines required outside of the fuel tank. The stock G-Series fuel line is 3/8" already from the factory, no need to replace that and add a regulator. BMW from the factory uses an electronic dampener/regulator combo, so this eliminates the need for aftermarket FPR. Super smooth install once the pump is removed and wiring is a breeze. We also DO NOT use zip-ties like the competitors do. We made it easy for you guys no matter what setup you're running in terms of fuel pump activation. Fuel System upgrade is required over 500-550WHP

Take your B58 or S58 build further with the JB4PRO Flex Fuel Add-On Harness—a simple, plug-and-play way to add an ethanol sensor and optional fuel pressure sensor to your JB4PRO setup. Keep your install clean, your wiring organized, and your tune dialed to match every fuel blend in the tank. Why it matters: Plug & Play: Connects directly to your JB4PRO—no cutting or splicing required. Sensor Ready: Supports ethanol and fuel pressure sensors for precise, real-time fueling adjustments. Clean, Safe Installation: Includes a 12 V adapter and inline fuse for hassle-free integration. How it works: This harness links your JB4PRO tuner to your flex fuel hardware. It’s not a complete flex fuel kit—you still need a compatible ethanol sensor—but it gives your JB4PRO the accurate readings it needs to adjust timing, boost, and fueling for E30, E50, or E85 blends.
