Turbosmart TS-0404-1042 FPR10 Fuel Pressure Regulator -10AN Black 35-80 PSI

Vehicle Fitment

• Universal - Compatible with any turbocharged or naturally aspirated fuel-injected street or race vehicle running a -10AN / 10AN fuel system; not vehicle-specific

Fitment Notes

• Designed for EFI (Electronic Fuel Injection) applications requiring a standard pressure range of 35 psi to 80 psi
• Suits -10AN (10AN) fuel system plumbing on inlet, outlet, and return lines
• Not for use with carbureted or low-pressure systems - use the FPR10 LP (TS-0404-1142) for 3-20 psi applications
• Suitable for fuel systems supporting up to 3000HP
• Compatible with all fuel types including pump gas, E85, race fuel, and aggressive leaded fuels
• Not CARB legal - not for sale or use in California

Features

• True 1:1 boost-referenced ratio delivers class-leading fuel pressure response and precise air-to-fuel ratio control under all boost conditions
• Stainless steel valve seat provides long-term durability and compatibility with aggressive fuel types including race and leaded fuels
• Milspec diaphragm construction ensures consistent, leak-free pressure regulation across the full operating range
• Unique locking collar design allows fast, tool-free pressure adjustments without requiring full disassembly
• 1/8 in. NPT gauge and pressure sensor port for direct connection to fuel pressure gauges or data logging sensors
• Superior flow and bypass capacity for high-output fuel systems up to 3000HP
• Adjustable pressure range of 35-80 psi covers a wide spectrum of EFI fuel rail requirements
• Hand-assembled at Turbosmart's Sydney, Australia factory under strict quality control standards
• Available in multiple anodized colors - Black (TS-0404-1042), Blue (TS-0404-1041), Purple (TS-0404-1043), Red (TS-0404-1044)

Product Description

The Turbosmart FPR10 (TS-0404-1042) is a high-flow, -10AN fuel pressure regulator engineered for EFI-based street and race builds demanding precise, stable fuel pressure control from 35 to 80 psi. Built around a true 1:1 boost-referenced design, the FPR10 automatically compensates for rising manifold pressure to maintain a constant fuel pressure differential across the injectors - an essential requirement for preventing lean conditions and protecting engines under boost.

The FPR10's stainless steel valve seat and Milspec diaphragm set it apart from budget regulators, ensuring compatibility with all fuel types - including E85, race fuel, and aggressive leaded blends - while delivering consistent performance over extended use. The locking collar adjustment system allows quick, precise pressure changes on the fly without tools, and the integrated 1/8 in. NPT port accommodates a fuel pressure gauge or sensor for real-time monitoring. With the capacity to support fuel systems up to 3000HP, the FPR10 is equally at home on a built street car or a dedicated race platform.

Installation requires routing -10AN fuel lines to the inlet, outlet, and return ports - all included fittings use the -10AN standard for a clean, uniform plumbing setup. Builders running carbureted or low-pressure systems should instead select the FPR10 LP variant (TS-0404-1142), rated at 3-20 psi. The FPR10 is available in Black, Blue, Purple, and Red anodized finishes to match the aesthetics of any engine bay build.
