Help!!!
 

I'm trying to empty 50 gallons out of the old fuel tank so I can remove it. I unhooked the gas line at the bulb and added a small piece of hose down into a small gas tank. When I pump the bulb it flows out then stops...no steady flow...not even a little. I plugged the end with my finger to build pressure and still zero flow. WTF?

Get to drinking!! LOL

I had the same problem!! I put a hose right into the tank threw the float hole and it worked fine, but still a slow flow!!

I had a friend use a drill pump and that was fine also.

the snti spihon valve is preventing the fuel from siphoning out, take the barb fitting off the tank pick up adn re[place with a regular barb( the siphon check valve is inside the barb). If you use a drill pump, be carefull, the drill motor is not shielded for sparks, it can cause explosions in the presence of gas fumes. I took an auot store electric fuel pump, rigged it up pulling thru a racor fuel filter and use it to pump fuel, better yet, I just polish the fuel by running it back in the fill, cleans all the crap out of it, mix it with fresh and you're good to go.

Thank you gentleman! I'll get the valve tomorrow and start again tomorrow. The gas is new so I'm gonna pump it in to cans and into my truck. New belly tank coming Friday! Then the fun begins of tearing it out!

Would it be possible to buy a crank style siphon kit from some wal-mart/ K-mart store and just siphon from the fill opening? I'm looking at buying one to service my tractors, boats, trucks, 4wheeler, gradall and whatever else needs to loose some fuel.

You probably did this, but just in case you forgot: open up the fill hole (gas cap) to allow air through.

I did not open the gas cap.....will try tomorrow....will I still need to remove anti siphon nipple and replace with reg nipple...nipple nipple?

If you can't get the proper volume of air to replace the volume of fuel, then you won't have any flow. An example from college would be to; try to shotgun a beer without punching a hole in the bottom of the can.

OHHH! NOW I UNDERSTAND PERFECTLY!! :beer:

the tank should be vented thru the tank vent, if opening the fill cap helps, you should check your vent line
