Where is fuel filter on ti7000lxr diesel generator

diesel oil 20w -30 for normal ambient temp areas

Who made the motor on it?

The purpose of any diesel fuel filter is to remove foreign particles as well as water. The use of a suitable filtration system on diesel engines is a must to avoid damage to closely fitted injection pump and injector components. Filter's ability varies between the type and manufacturer. On diesel engines primary and secondary filters are used. The primary filter is capable of removing dirt particles down to 30 microns and the secondary filter between 10 to 12 microns. Secondary filters are available between 3 and 5 microns, which are used in severe service operations. The primary filter is usually located between the tank and the supply pump, the FWS is one type of the primary filters. The secondary filter between the supply pump and the injection pump.The basic working principle of fuel filter for diesel engine mentioned above is share by Jiangsu Starlight Electricity Equipment Co.,Ltd. Hope it is useful for all users. Besides, our company can provide a variety of specifications common from 3KW to 2500KW, automated, four-protection, automatic cut over, low noise and mobile and so on high quality, and the low energy consumption generator set so as to satisfy the customer all electric power demand. We can also satisfy the user different voltage, different frequency request, as well as many units and networking power supply system. More information about diesel generator at this link.

Check and make sure you can see oil in the oil resivior.sounds like its low on oil.

Visit the on-line store, know as reliable-store, they have the repair manuals. I'm sure you will get the solution of your problem. Best Manuals

See id it is actually pumping fuel and if so see if the glow plugs are getting hot.

gasoline generator I suppose? re-clean your sparkplugs, check air-filter, and adjust your carb to run leaner. if its diesel lemme know

Maybe it causes by the following problems:

Fuel System Failure

1. Air in the fuel system
This is a common problem that a diesel generator fails to start normally.
Solution: Check whether the fuel oil pipe connector is loose or not, and ensure that the air is cleared from the fuel system. Loosen the bleed screw bolt on the diesel filter, and then use the manual oil pump to pump the fuel until the air bubble is gone.
2. Fuel Line Obstruction
Solution: Check whether the pipeline is smooth or not.
3. Fuel Filter Clogging
Solution: Clean the filter or replace the filter element
4. The Handle Position of Fuel Injection Pump Is Not Correct
Solution: The handle position should be pushed to no-load when starting the diesel generator set. Rotation speed is about 700-900r/min.
5. Fuel Injector Problem - Little fuel injection or fuel injection is not atomized
Solution: Remove the fuel injector, connect it to the high pressure oil pump, pry the fuel injection pump plunger spring and observe the spray condition. If necessary, wash the injection pump.
6. Oil Supply Problem - Oil transfer pump doesn't supply oil or the oil supply is brokenly.
Solution: Check whether the oil inlet pipe is leaked or not and the filter screen on the oil inlet pipe connector is blocked or not.

Here is some reasons and solutions for diesel generator fail to start:
1. There is air in the fuel systems
Check if the fuel line connection is loose and remove air from the fuel system. First unscrew the exhaust screws on the injection pump and the fuel filter and pump the oil with the hand pump until there are no bubbles in the spilled fuel. After, tighten the exhaust screw. Pump oil again, when there is return oil in the tubing, then tighten the hand pump. Loosen the nut of the high pressure tubing at one end of the injector, pry high injection pump plunger spring seat, when there is no bubble in the fuel out of the nozzle, spin the nut, then pry a few more times, so that each cylinder injector is filled with fuel.
2. The fuel line is blocked. Check if the pipeline is unimpeded.
3. Fuel filter block. Clean filter or replace filter.
4. Oil pump does not supply oil or intermittent oil supply. Check that the inlet pipe is leaking, and that the filter screen on the inlet joint is blocked. If no oil is supplied after removal, the intake pipe and oil pump shall be inspected.
