A large 8AN feed line runs around the backside of the fuel tank. This line mates to a new 6 micron microglass high flow fuel filter mounted in the OEM location using a billet mount. An 8AN PTFE fuel line runs from the fuel filter along that factory hard lines, as shown.
This 8AN PTFE line feeds the RA-series fuel pressure regulator (FPR) mounted under the RH strut tower. From the FPR, an 8AN PTFE fuel line feeds the front port of a dead head aftermarket fuel rail (not included). The Mazda 1.6L B6 Fuel Rail or Mazda 1.8L BP Fuel Rail are sold separately. The OEM fuel feed line is repurposed as a high flow return line. The OEM fuel line connects directly to the FPR return fitting.
A fuel pressure gauge mounts directly to the feed line for easy adjustment.
