Does the Monarch Premium Fuel Cap allow jet fuel to be introduced into the tank?
No, our inlet is 1.5″ at the widest point to keep jet fuel nozzles out. Your insurance company may give you a discount on your premiums or pay for a portion of these caps due to this fact. Usually all they need is something in print. (such as this document) If they need a formal letter or a drawing, we will be happy to provide it to them.
