System Features and Functions
System controls are all microprocessor-based. Solenoid valves, and electro-mechanical switches have
been eliminated to increase reliability. A membrane switch operators panel and LED readouts provide an
extremely simple operator interface.
The system operates on any D.C. voltage between 8 and 30. Automatic electronic voltage control reduces
stress on the pump motor.
A manual pressure control valve and mechanical pressure gauge are located on the top of the cabinet. With
the pressure control valve fully open (counter-clockwise) the pressure is internally regulated below 15 psi
for typical services. Some diesel injection systems such as HEUI and some common rail engines require
higher pressure from the lift pump to function. The pressure can be increased to match the pressure
specified by the manufacturer by turning the pressure control valve clockwise.
A built-in self-test at power up verifies electronic functions, while continuous monitoring during
operation verifies that parameters are within tolerance.
The noise level of this equipment was tested and a maximum level of 63 dB (A) was measured.
A fill adapter allows the system mixture tank to be filled from the vehicle's fuel tank or another fuel
source. Fuel level is continuously monitored. Fuel siphoning adaptor MV p/n 061-0001 comes with a
3/8" (10mm) in-line fuel filter. Any inline filter with minimum flow capacity of 3 to 5 gallons per minute
(11 to 19 LPM) is acceptable as a replacement, or it can be purchased directly under MV p/n 050-0071.
A 4.6 U.S. gallon (17.4 liter) solution tank provides for multiple cleaning cycles without the need for
refilling.
All parts in the fuel path, including the tank, hoses, fittings, and seals, are made from non-corrosive
materials.
A spin-on canister fuel filter provides quick filter changes.
A two-stage electronic programmable timer monitors the elapsed time, and sounds both a soak alarm and a
shut-down alarm. A mixture level monitor sounds an alarm for an impending fuel shortage or out-of- fuel
condition.
