Overall sentiment: negative
Customer reviews:
This hose is junk. This hose should not be put on anything . DO NOT BUY THIS IT IS FUSTRATING TO USE . 
 Expected larger diameter siphon hose with more capacity. 
 Just about ok 
 Does not work very well, especially in the cold. 
 Basically USELESS,  unit was coiled in a package,  all the hose would not straten out and remained coiled,  so useless.
The suction bulb was depressed in the pack,  rendering it less effective.
DO NOT PURCHASE THIS ITEM FOR fuel pumping. 
 First of all, the tubes do not want to uncoil so you are constantly fighting to keep them between the two points of interest.

Second, the bulb does NOT have a one-way flapper valve!  Unlike the primer bulbs on outboard motors and other engines the bulb simply squeezes! So, besides having to keep the hoses unrolled, you have to try to put one finger over the outlet end when sucking the fluid thru the other end.

I didn't even bother returning it to Amazon, I threw it in the trash.  Really they should be embarrassed to allow a vendor to sell this piece of junk ontheir website.  Do not waste your time or money on this PoS. 
 First of all, its tiny. This is like 1/4 inch hose, which should be fine if all you want to use it for is a fish tank. Second problem is, it doesnt work. There is no one-way valve anywhere in it, so all it does is blow bubbles. 
 The dang tube holds it coiled up shape even after trying to stretch it out overnight. The squeeze bubble doesn't work either. Had to resort to the old fashioned way of sucking the other end to get a flow from the tank. Just use a thicker piece of all purpose hose for the job. 
 It leaks if you just use it out of the box. The point was not to get gasoline all over myself and the first time I pumped the Siphon, gas came running out on my hands. Buy two little hose clamps and fit them over the connection between the tube and the Siphon pump. Make sure the clamps go over the black part of the Siphon pump that connects to the tubes.
Problem solved. Works fine now. If you are unwilling to modify it, then expect leakage or buy something different. Secondly, I was browsing in my local Wally Mart and there was this same pump(made by Pennsoil) for $2 less, which would easily cover the cost of the little hose clamps which money to spare. 
 I got this product and the hoses in the package were all kinked up and i FOLLOWED THE INSTUCTIONS and it didn't siphon anything I tried for an hour and maybe got 12 ounces of gas out terrible product I guess you get what you pay for. 
 Way over priced!
The materials in this were at most 50 cents and I paid $6 as I recall
