Fragola Fuel Pressure Gauge 0-100 PSI Liquid Filled

This engine parts collection covers oil catch cans, thermostats, thermostat housings, radiator components, coolant accessories, engine covers, fuse box covers, cap covers, throttle bodies, supercharger pulleys, idler pulleys, tensioner pulleys, and engine bay dress-up parts for trucks, SUVs, muscle cars, boosted builds, high-horsepower street cars, and performance vehicles that need better reliability, cooling, airflow, oil control, and under-hood styling. The collection is particularly strong for Dodge Challenger, Charger, Durango, Jeep Grand Cherokee Trackhawk, and Ram TRX platforms running 6.2L Hellcat, 6.4L HEMI, and 5.7L HEMI engines, where oil catch can and cooling upgrades address known OEM weaknesses in the PCV and thermal management systems. Import performance platforms including GM LS-based builds, Chevrolet Camaro, and Corvette applications are also represented through Mishimoto, CSF, and ZPE GripTec product lines. Builders who invest in engine bay organization and reliab...

Fragola Performance Systems has manufactured AN fittings, PTFE hose, and plumbing hardware in the United States since 1979, supplying professional race teams and serious street builders who cannot afford a failed fuel or oil line at speed. The brand's manufacturing standards exceed SAE J1645 requirements, and every fitting is pressure-tested before leaving the facility in Clover, South Carolina. Builders who specify Fragola on a fuel system, oil cooler circuit, or brake line are choosing a product with a documented motorsport history across NASCAR, IndyCar, and NHRA drag racing.Popular UpgradesFragola's Series 3000 PTFE hose is the most popular choice for high-heat fuel system plumbing, rated to 450 degrees Fahrenheit and compatible with all fuel types including ethanol blends and methanol. Series 8000 and 8000LL hose assemblies suit high-pressure power steering and brake circuits up to 3000 PSI. Swivel seal fittings, 45-degree and 90-degree elbows, bulkhead adapters, and O-ring fac...

A properly designed fuel delivery system is the backbone of any high-performance engine build, ensuring the injectors or carburetor receive a consistent supply of fuel at the correct pressure regardless of engine load, RPM, or fuel demand. From factory replacement pumps keeping daily drivers on the road to high-flow in-tank modules supporting 1000-horsepower builds, the right fuel delivery components prevent lean conditions, injector damage, and fuel starvation at the worst possible moment. Modern EFI systems are particularly sensitive to fuel pressure variation, with even small drops causing misfires and power loss under hard acceleration. Whether you are restoring a factory system or engineering a purpose-built race setup, matching pump flow rate and fuel pressure regulation to your injector and engine requirements is essential.

A fuel pressure regulator maintains consistent rail or bowl pressure regardless of engine demand, fuel pump output variation, or manifold vacuum changes, acting as the pressure control valve that determines how much fuel the injectors or carburetor actually sees at any given moment. In return-style EFI systems, the regulator bleeds excess fuel back to the tank while holding the supply side at a precise setpoint, typically 43.5 PSI for most port EFI applications. In boost-referenced setups, the regulator increases fuel pressure proportionally with boost pressure to maintain a constant fuel-to-air pressure differential as manifold pressure rises, preventing the injector effective flow rate from dropping under boost. Selecting the correct regulator type, pressure range, and port sizing for your system determines how accurately fuel delivery tracks engine demand across the full operating envelope.
