CLEANFIRE FUEL INJECTION
PUMP FLANGE ASSEMBLY
FUEL PUMP
This fuel pump is non-serviceable and can not be replaced. If
fuel pump fails you will need to replace the whole fuel tank
assembly.
FUEL PUMP: Located inside tank. It provides system with
fuel at 116psi (8bar) pressure. If the fuel pressure is suspect to
be defective apply 12 VDC to the fuel pump prime (Red (#1)
and the Brown (#3) wires) and check for audible fuel pump
operation as well as fuel rail pressure. The fuel pump should
sound when pumping and the pressure should show 116psi (8
bar) pressure.
FUEL LEVEL
If the fuel gauge is suspect to failure you can check the
continuity from the fuel sender to the gauge. The given
resistance below is from the Violet/White (#2) wire to the
Brown (#4) wire located at the front of the fuel pump.
FUEL RAIL
