The subject innovation relates to a connecting means for connecting the fuel filter and the fuel pipe, a packing that connects the conventional fuel tank and the fuel filter was unable to conclude not really suit the ball fastening even align the center of the seal and the plunger, a volatile strong fuel the corrosion of the packing to the application of the adhesive faster to the surface of the packing there is a problem that corrosion is fast pine nuts, so the replacement and repair there is a problem in that economic losses and loss of fuel by abominations. The subject innovation is the adhesive on the surface of which is a problem in that by forming the fitting projection and the position fixing hole formed projecting to one side of the packing matchumyeo facilitate the center fastening hole of the packing and the plunger, volatile corrosion quickly by the strong fuel packing does not applied and extended the packing life, exchange and does not frequently repaired prevent economic loss and loss of the fuel generated demyeo, it does not apply the adhesive to the packing speed of the working hours of the production line and increasing work efficiency, and It is characterized in the improvement and reduction of production cost of the working environment of the unused adhesive made.
