Malpassi EFI High Rising Rate Fuel Pressure Regulator 1:2.5

PROGRESSIVE PRESSURE INCREASE REGULATOR – "Rising High Rate" PRODUCT CODE: 30091 HR 384 Replacing the stock regulator with an adjustable regulator optimizes the performance of the standard injection system. As with the Rising Rate regulator, with our Rising High Rate the variation of the base pressure, with the same boost or depression, is no longer "linear" but "progressive". Also in this case we have the possibility of gaining weight as the rpm increases while maintaining a clean and regular idle, but since the air/fuel ratio is higher (1:2.5) the amount of fuel sent to the injectors is much higher, so the injectors themselves and the pump must be adapted to the required pressures. It has been designed to provide a stable supply pressure combined with a high flow rate under all load conditions. Suitable for tuning, motorsport-racing. Our regulator is made of special alloy casting, and each piece is assembled manually and individually tested to ensure maximum operating precision.
  • For applications on naturally aspirated and/or turbo
  • Air/fuel ratio 1:2.5
  • Compatible with alcohol fuels
  • 2 threaded IN/OUT ports 1/8" NPT
  • 1 x 1/8" NPT threaded RETURN port
  • 5 mm diameter vacuum and/or boost connector, on 6×1 mm threaded port
  • Adjustable base pressure from 1 bar to 8 bar (with suitable pump)
  • 2 1/8" NPT connectors (8 mm diameter hose connector) + 1 1/8" NPT end cap are supplied
  It can be mounted in a by-pass configuration (3 connectors are required) between the pump and the flute or in a standard configuration downstream of the flute, on the return line (in this case one of the two IN ports is closed by the 1/8" NPT cap, which can be replaced by a sensor or pressure gauge socket). Various models of flute adapters are available separately for replacing the original regulator and other types of 1/8" NPT connectors with various models of rubber port, according to user specifications. All regulator models with a 1:1 and/or 1:1.5 ratio can be supplied in a Rising High Rate (HR) version with a 1:2.5 ratio.
