Building a Fuel System for a 500hp Honda
This is the companion guide of this YouTube video. For full context watch the video.
The goal of the system is to fuel my built turbocharged B18C to the tune of 500 horsepower. By my estimation this fuel system could support a forced induction 4-cylinder engine up to 700hp. This build is for a race car intended for use on private courses. Modifying your fuel system can be dangerous if done improperly. Consult a qualified professional.
This is my parts list (I will be replacing the fuel cell with an FIA-approved bladder cell but the system will work the same):
- 2 x AEM 50–1005 Fuel Pump
- FuelLab 81802–1 Fuel Filter (10 micron)
- Fuel Lab 81822–1 Fuel Filter (75 micron)
- 60mm Fuel Pump Bracket
- Aeromotive 13129 Adjustable Fuel Pressure Regulator
- AEM Fuel Rail
- DNA Motoring 12 Gallon Fuel Cell
- 2 Liter Aluminum Surge Tank
- Bosch 1000cc Fuel Injectors
Below is the hose diagram for routing fuel between the components. Note that all of the feed lines (from fuel cell to fuel rail) are -8AN PTFE and all of the return lines (from fuel rail to fuel cell) are -6AN PTFE.
The fuel cell has -8AN fittings but the surge tank has -6AN fittings so an adapters is used on the feed line from the 75 micron filter to the surge tank. You will need -8AN fittings for the…
