The yellow tubing is tygon and the black is Dubro Neoprene. I do not know what is on the hand crank pump, just make sure that it is for gas/diesel. With the cap properly secured with teflon tape (plumbing supply) on the threads, (smear some castor oil on the new teflon tape before putting the cap on), you will not lose ether. Please read the text of my post and save yourself a lot of bother that I had to learn on my own. However I must give credit to Norm Rosenstock who published a similar design for quart cans and using gravity feed. I modified his idea for gallon cans and a hand crank pump.
