Then we we remove the oil return pipe OE2124600381 at the oil tank, after removing the oil return pipe, we connect the connector with our own oil pipe, and fasten the oil inlet and oil return port with a wrench.
Then we need to tie the fuel line, not on top of the low voltage line, but under the low voltage line, because if the fuel line leaks above the harness there is a possibility of starting a fire, that is, the car spontaneously combusted.
After we tied the harness and fuel line, connect the fuel inlet fuel line to the engine, or the fuel filter in front of the engine, depending on the model, some do not have a filter, because there was one in the tank.
Next we connect the engine return fuel line OE2124602524 to the engine return and that's it, so it's hooked up, very convenient, right?
If one of your oil pipe leakage, it is also possible to connect directly from the center, no need to re-build the oil pipe or change the oil pipe, as shown in the following figure: find two joints on it, now do what is very convenient, all have tools.
The way to drain oil from the fuel line:
One, you can open the oil drain ropes on the gas tank. Of course, you can't do it without the drain wire.
Second, you can stretch the pipe from the gas tank filler neck and suck it in. When inserting the pipe, use a stick to open the valve in the gas port, otherwise it will not be inserted.
Third, you can disassemble the engine oil return pipe OE2114604124, while the car is connected to the oil. Be careful not to let the oil splash out, especially not on the distributor system. Easy to catch fire. Of course, there is a small part of the car does not have a return pipe. That will not work.
Four, you can remove the oil feed tube OE2514603324, find the oil pump relay, use the wire across the oil pump relay to make the oil pump work, and connect the oil from the oil feed tube of the engine.
