Fuel Injection Layout

Injection layout

Note that without return lines to the main tanks, it is imperative that all the lines be well-insulated.  Otherwise, under low-load conditions, the temperature of the fuel in the swirl pot will get too high.  To prevent this, it's also possible to add return lines to the tanks with a T at the injector return line and electrical shut-off valves driven by the appropriate fuel pump power lead.
