Pink fuel?

I have a new to us 425f from 1994. I've cleaned up all the dirt and grime and, based on the advice here, I'm emptying the fuel tank and will put fresh in. When I emptied it, the fuel that came out of it was pink. Any idea what that would be? I know that Coleman sometimes has a bluish tint, but I've never seen pink fuel before. Did the previous owner run gasoline through it? Is that pink?

Thanks!

 

sounds like agriculture or farm gas they dye it pink. it is sold as a low tax fuel for farm equipment--dont get caught with it in your tank in a private vehicle!

 

Thanks. Do you think it's fine for me to burn a little bit in this stove? It isn't dual fuel. I got out a lot of it, but man, it's difficult to completely empty the tanks.

 

pump gas is hard on stoves the additives tend to clog things up. if your not going to use it right away set it out side and leave the fuel cap off, if its warm out it will be gone in a day. but do get out as much as possible old gas let alone pump gas is not good for it.

 

Sometimes fuel left in a Coleman for a long time will pick up a little color from the brown/red epoxy that the factory lined tanks with.

 

Evaporation will most likely leave the additives behind in the tank.
I would remove what I could, add fuel, and burn it.

 

Thanks everyone. This is exactly what I did. I got what I could, and then filled it up to dilute what was left. I fired it up, and got a really nice blue flame out of both burners. Hopefully, I can burn out whatever it is without leaving too much crud behind.

 

Coleman fuel has had different colored dyes over time that I've seen. The gallon cans were dyed blue or green. The red plastic quarts (expensive) had a red dye, so yeah, would be a pinkish color. If it smells sweet like Coleman fuel, it may very well be.

 

Well done but you now know whats required. Pics of it running

 

AVGAS 80/87 used to be called ''Red'' and had a pink tint. It was leaded. That was quite a while ago. Obsolete as aviation fuel now.
Most likely, it's the Coleman gas Jim L mentioned above.

 

Shoot! Should have taken a pic! Next time.

 

If you had been this side of the Atlantic I'd have said make sure it's not paraffin / kerosene. To compete with "Esso Blue", you could also buy "Pink Paraffin" in the UK.
