Set of 4 Kevlar Tanks for this fantastic Jet. The 3 conformal Kevlar fuel tanks provide a generous 6.8 liters of fuel and 2 liters of smoke oil (1 conformal tank) to satisfy any size motor’s appetite. The custom oversized 3/16th fuel tank fittings that are provided may seem like overkill, but experience has taught us to go with larger diameter fittings to ensure that there are not ANY fuel delivery restrictions to the fuel pump.
