This question, unfortunately, was the last in the life of a motorcyclist attempting a match to light the dark failure of the fuel… This, of course, a joke but in every joke there is truth. But the truth is that motorcycles and mopeds usually are not equipped with a level gauge of fuel in the tank. However, for those who love tinkering, we offer two simple designs of such signs.
The first is the most simple, based on the principle of communicating vessels. For starters, instead of the regular fuel tap with filter and screw the sump into the tank from the motorcycle “Ural” and “Dnepr”, which is not one fitting, but two — the number of carburetors. One of fittings connect the standard hose to the carb, and the other pull the clear plastic tube and secure it in a vertical position on the wall of the fuel tank wide ribbon-tape Top tube plug plastic tube with a drainage hole, pierced with heated pins.
While the water is the upper limit of the fuel in the tube-the pointer will coincide with the level in the tank. If you wish, by a transparent tube it is possible to put a scale calibrated in litres or fractions of the volume of the tank (1, 1/2, 0).
Hydrostatic fuel gauge:
1 — dvustoronniy benzaken; 2 — regular fuel hose; 3 — a clear plastic tube; 4 — “Scotch”.
The second design is a level indicator of the float type. This device has a very corporate look and looks like a normal gauge, mounted on the side wall of the fuel tank to Make such a pointer are quite capable of every biker.
It is arranged as follows. On the side wall inside the fuel tank is mounted to the base pointer (metal plate with a thickness of about 3 mm), which is axis (M4 screw) hinged on her duplechin lever (steel wire with a diameter of 2 mm). On the long end of the lever is the float (a plastic bottle), and the short end is the arrow pointer fuel level. In the wall of the fuel tank (and at the base of the unit) cut a rectangular hole covered with the outer tank side plate plexiglass. To provide a tight seal between the tank shell and Plexiglas window provides a gasket of rubber or benzokolonki autoerotica.
Float fuel gauge:
1 — scale, 2 — wall fuel tank; 3 — mounting screws M3; 4 — transparent plate (plexiglass); 5 — base of the device (s3 aluminum), 6 — the lever of the float (steel wire Ø 2), 7 — float (a plastic bottle); 8 — nuts scale; 9 — lever axle (screw M4).
The inside of the tank (directly behind the arrow pointer in front of the window) mounted on metal scale white color, against which the black arrow is clearly visible. The scale is calibrated in liters or fractions of fuel tank capacity.
The entire device is going out of the tank, and in the manufacture must ensure that its dimensions after Assembly was allowed to enter the device through a relatively narrow throat Assembly can be facilitated, passing through the neck of the tank and penetrated into the wall of hole of soft wire. the wire is passed through the hole in the base of the pointer and the mechanism crouched reserved for him the place Remains loosely install the screws, pull the wire-guide, and then natugo tighten.
