Which tank stopper is kero safe? The gas or glow ones?

Use the Gas , NOT the glow. I think the Dubros are red in color.

Thank you kindly, Mr. Chris. I have both handy, so no sweat. Ever come down to Floyd Bennet to fly?

You must use the gas versionfor turbine use. Now, be very careful about going with 'just' color. There are a number of suppliers that have red, white and black colored stoppers. Generally, the white colored ones are glow and generally the red colored ones are gas but black ones can be gas or glow. The black stoppers that have a raised O on the face indicate gas use. Bottom line DON"T GET THEM MIXED UP otherwise you will have a mess on your hands ( personal experience with the black ones !! ).

Enjoy

Thanks, Dean. That could come up as mighty important. Explains why I had a black "gas" stopper bulge up and freak out a couple of years ago with a diesel engine.
In this case, I have two new red dubro ones that are in their packaging, so I know just what they are.

If you have purchased the BVM aluminum fuel caps, the black stopper (it comes with one of each) is the one for kerosene. But then again, if you bought this from BVM, the included instructions make this clear.

I KNEW I shoulda just gone BVM...
