oh my bad. But i agree with disrespective and himalayan.
Direspective's suggestion is really good and only meant for those who have done this before or else you will end up tasting petrol.
Ha Ha, You are right, i had tasted petrol sometimes. Then my father thought me another method. Just put the tube fully inside the tank so that only tip is outside of the tank. Then block the mouth of the tube tightly so that no air goes inside. Now when you pull the tube out [not fully] you can see the petrol stuck at one point. Make sure you take out good amount of tube with petrol and then open the mouth at the bottle. that is it.
I use the same method for cleaning my fish tank.
Hope if you are chemistry student you should have done this so many times in lab in small way
I dont know the reason, couple of time i got into a situation where I have tank dry in my bike and tank full in car. and I want fuel in my bike.
Are you in the same situation?
