As further specifying of such scheme:

Preferably, described main body is provided with connection screw and the mating face that is used to connect diesel-oil filter.

Preferably, described in-line is the clear opening that two ends are provided with internal thread, and its two ends are respectively fuel tank oil out port and high pressure oil pump oil-feed interface.

Preferably, described return line comprises that two ends are provided with through hole and two perpendicular tapped holes that communicate of internal thread, this through hole and two ends parallel with in-line are respectively high pressure oil pump oil return interface and tank drainback interface, and two tapped holes of described return line are respectively equipped with oil sprayer oil return interface and common rail pipe oil return interface.

Preferably, described main body sidepiece is provided with two support plates, is provided with the assembling screw on this support plate.

Preferably, the end face of described fuel tank oil out port and tank drainback interface is provided with and flows to indicating device, and this flows to indicating device is the indicating arrow that is depression or convex.

The beneficial effect that the utility model adopts above technological scheme to reach is: fuel dispenser described in the utility model with all of engine fuel oil system advance, oil return all gathers, distributes by fuel dispenser, make the distribution of oil-fired system pipeline and arrange conveniently simple and clear, and can also be as the diesel-oil filter support, not only simple and compact for structure, and easy to maintenance, with low cost.
