If the Viper or Scorpion is for anti-icing additive: NO! The neoprene seals work great with anti-icing additive but are not compatible with fuel. Pumps for other additives would be OK, but it is preferable to test with the additive the pump is intended for. There is no rubber compatible with both jet fuel and pure DiEGME anti-icing additive – a.k.a. “Prist” or FSII. We do provide replacement seals at a small charge.
