Question: How do I install the Fuel Tank into my VMAR Hornet 40-52ARF?
Answer: This is not difficult but the instruction book does not cover this directly.
Do the fuel tank setup first. Install the internal tubing and clunk(s). When the stopper has been tightened but not overtightened, install pieces of fuel tubing between or over the ends of the metal pipes to seal them against dirt and debris. Mark the back of the tank with an arrow pointing up so that you can clearly see which way the tank is to be positioned in the model.
Remove the black sealing gasket from the fuel tank. Apply sealant such as Pacer Dap-A-Goo to the front face of the tank around the neck and re-install the gasket. Apply more sealant to the front face of the gasket.
Insert the tank into the fuel tank compartment with the tubes forward and oriented so that the top of the tank is positioned correctly. Press the tank firmly against the back side of the firewall and secure in place while the sealant cures.
From the engine mount area, apply more sealant around the neck of the fuel tank working from the front of the fuselage.
When the sealant has dried, support the tank with sponge foam around the sides and bottom of the tank. You may wish to install your battery pack beneath or behind the tank before inserting the sponge foam. |
