55.  When the hysol is dry, you can paint the horns and 

fillets to match your airframe for better appearance. 

 

Figure 55 

56.  By now, the silicone holding the tanks should be dry, 

let's get back to the fuel system. Make up a tygon 
harness to link the outer tanks to the center one. 

 

Figure 56 

57.  Use this to connect the fuel outlets of the outer tanks to 

the vent of the center tank. Keep the tubing lengths to 
the outer tanks identical. 

 

Figure 57 

58.  Make up another y harness as shown. Leave the third 

line long, it will need to reach forward and function as 
an overflow when you fill your tanks. 

 

Figure 58 

 

 

59.  Use this harness to connect the vents of the outer 

tanks, and then tape the overflow line out of the way 
forward. 

 

Figure 59 

60.  Now add a length of tygon to the fuel outlet of the 

main tank. Leave this one long enough to reach to 
your UAT, which will be mounted forward. 

 

Figure 60 

61.  Secure all lines with tie wraps.  You may find it easier 

to partially tighten the tie wrap on the line further out, 
then slide the tie wrap down the line to the tank and 
tighten. 

 

Figure 61 

62.  Install your sequencing valve and servo and linkage 

to a scrap plywood mount. The UP3 valve is shown, 
but others such as the Jettronics or other sequencing 
solutions are fine.
