Adjustable Rising Rate Fuel Pressure Regulator
The Cartech regulators are designed specifically to add fuel to modified EFI engines (turbos, superchargers and normally aspirated).

Our original FMU, introduced in 1975, has been copied six times and is still used by four companies.  The 2020 series regulator is the fourth generation design to come from Cartech, and every new design has been better than the previous. Imagine how vastly better these new designs are than that 25 year old relic the other guys are still producing! Cartech FMU for $270
