My Harley loses gasoline for the deposit of the deposit. How do I repair it?

I will start this totally practical article theorizing about the composition of current gasoline.
The gasoline that we find at the moment in the warders can contain up to 5% ethanol (biofuel produced through cereals) without the oil company having to indicate it. The truth is that except for the classics, the majority of modern vehicles are prepared for this mixture, as long as they do not exceed 5% (according to various sources it is increasing up to 10%). A couple of important considerations to consider are:

• Ethanol is much more corrosive than gasoline: it can affect soft ties in carburetors, injectors and other components of the fuel system if the vehicle is not prepared.
• The ethanol should not be left stored with the vehicle stopped too long, since it creates varnishes very easily, and can cause system malfunction.

This said that the current percentage allowed by law is very low, so we will not generally find problems of this type.

The problem
Although the concrete cause has not been demonstrated, it is a fact that in recent years there are failures in the fuel systems of the motorcycles related to corrosion in toric joints, which when degraded lose their ability to pond.
A concrete example has it in the fuel taking of Harley-Davidson motorcycles with injection. This rapid disconnection is subject to the pressure of the fuel pump, to the vibrations (it joins a fixed part, the chassis, with a "mobile" part, the engine) and to the extreme heat due to its proximity to the butts. These conditions (and perhaps the composition of the new fuels) make damage to the toric joints, which entails the typical loss of gasoline.

Options
Normally repairing this leak implies changing the high pressure of the fuel tank, quite expensive option for the cost of the components and for the time in labor necessary for the operation.

An American company called Fuel tool (in the use of ethanol mixtures are even higher) has created a economic repair kit That allows us to restore and improve fuel taking, as it uses viton joints, very corrosion resistant.

As can be seen in the photograph, the kit also has the Repair tool game.

Disassembly
We will proceed to repair a fuel shot with loss, we will start emptying the deposit, then we will remove the fuse of the injection and try to start the motorcycle, this refersuries the system. We can already disconnect the quick shot, pushing the blockade up.

We will now use the garf and the extraction tool with the “A” brand.

After inserting the tool and turning it we will see that “click” the lower O -Toric Board and we can already extract it.

We repeat the operation with the “B” tool, thus extracting the upper toric and the safety valve, which we will also replace.

Mounting
After ensuring that everything is perfectly clean, we will lubricate with a little specific oil the new joints and valve and introduce them into the installation tool,

After which we will gently push the installer's plunger until we notice a “click” that will tell us that everything is in place.

The last step is to install the lower O -Toric Board, using the “A” tool again.

Testing
Made the assembly we can already connect the sleeve again and fill out the fuel tank, we will start the motorcycle and verify that there are no leaks or friction between the components.
As a final verification we can perform a test with the Pressure tester of fuel, which will allow us to know at the same time the status of the pump and the pressure regulator. The pressure should be constant in any accelerator position, and be between 50-60 psi.

Problem solved, we can go roll, and we have achieved it in approximately one third of the time and economic expense that performs the traditional substitution.
