Unfortunatly, the BVM kits are supplied with a choice of only black or white stoppers. The black ones are supposed to be good for Kero. The web site also confirms there should be no problem with the black ones with Kero. I read the instructions, now I'm confused, and my jet is grounded.

Brown? I believe only Dubro has brown ones redily available. I will certainly test them. I will also be looking closely at the Kero. Could I have bad fuel? We'll see.

At work this week, I'm going to use Jet-A (JP-8) from a fuel sample we have to take prior to T/O, and soak some more stoppers.
