Choose an appropriate place for fuel standpipe installation and cut out a Ø39 mm hole in the tank; 2. Set the fuel standpipe into the tank and mark the sites for five Ø6 mm holes drilling. The drilling is conducted after the fuel standpipe extraction from the tank; 3. Overlay the fixing half-rings over the bearing surface outside the tank to the intent that the holes axis in the tank coincided with the holes axes in the half-rings. Without changing the half-rings position mark for the drilling of two Ø6 mm holes with the countersunk 1,5x45 for the sunk screws M5 head; 4. Remove drillings and sawdust from the tank appeared there during modification; 5. Establish two fastening half-rings through the Ø39mm hole inside the tank and secure by two screws M5 with flat head; 6. Establish the fuel standpipe into the prepared hole on the rubber gasket and fix to the half-rings by screws. Fuel in-line standpipe ÒÏ-100 connection The electric heater connection to the vehicular power-supply system is conducted according to the single-line schematic electrical diagram (see Fig. 2) using the wiring kit (wire color marking is shown in the diagram). In this case the wires, connected with the negative pole of the power-supply system, are connected to the vehicle body (cabin, frame, etc.) very close to the connected nodes. The relay and fuse are fixed under the cover on the dashboard. The wire from the nozzle’s connection plug to the cabin is laid along the existing wiring harness and fixed thereto by clamps. The illuminated switch is mounted in a convenient for the driver point on the dashboard (bore dimensions for switch mounting are shown in Figure 6). At a fuel standpipe complete set by switch without indication the LED with the holder is installed next to the switch. Thereby the connection to the vehicular power-supply system is conducted according to the schematic diagram (see Fig. 3) and Ø6,5 mm holes are drilled for the LED holder installation. The custom-made fuel standpipes may be connected to the power-supply system according to the double-line schematic electrical diagram (at a complete set by switch with indication – see Fig. 4, at a complete set by switch without indication – see Fig. 5). Fuel in-line standpipe ÒÏ-200 connection Fuel standpipe connecting to the engine cooling system is conducted by the flow-type rubber tubes (not included in the delivery set) according to the schematic diagram scheme – see Fig. 2. Bypass group is attached to the car body with the M6 screws and rubber tubes mounting is performed by clamps from the wiring kit. At rubber tubes mounting it is necessary to provide: - lack of kinks reducing the tube’s cross-section; - protection from abrasion in the field of attachment to the vehicle body, for example, with rubber gaskets; - protection from high temperature exposure in the exhaust manifold area. The electric heater connection to the vehicular power-supply system is conducted according to the single-line schematic electrical diagram (see Fig. 3) using the wiring kit (wire color marking is shown in the diagram). In this case the wires, connected with the negative pole of the power-supply system, are connected to the vehicle body (cabin, frame, etc.) very close to the connected nodes. The switch and LED with holder are mounted in a convenient for the driver point on the dashboard (bore dimensions for switch mounting are shown in Figure 7 and Ø6,5 mm holes are drilled for the LED holder installation). The relay and fuse are fixed under the cover on the dashboard. The wire from the nozzle’s connection plug to the cabin is laid along the existing wiring harness and fixed thereto by clamps. The custom-made fuel standpipes may be connected to the power-supply system according to the double-line schematic electrical diagram (see Fig. 5). |
