Briggs & Stratton help - Tilted Forum Project Discussion Community

Hi everybody, I'm not sure if this should go here, or in motors, but I'll give this a shot. Here's my deal, I have a new 3.5 Horse Briggs and stratton gas engine. I am going to be using it to run a pump jack on a well to pump water into a large livestock water tank in a pasture. Now I am planning on starting the engine and letting it pump water till the gas runs out, my problem is that the engine will run out of gas long before the tank is full. I would have to re-fill the gas tank several times in order to get the water tank full. I do not want to have to do this, as the tank is a few miles from my house and I am busy with other things. So I am wondering if this will work. A neighbor mentioned to me that I could mount a jug or some other type of container above the engine and run a line down from the jug and into the top of the gas tank on the engine. This sounds great, but then he commented that it doesnt work on all engines as it might flood out the carberator since the carberator is mounted above the gas tank. So my question to you fellow TFP'ers is will this work on a briggs and stratton? or is there some other way of rigging a larger gas tank to this thing?? Thanks for your help

Justin.

Another possible solution for you:

What about having an auxillary gas tank level with the main tank on the motor.... And have some tubing between each setup to act as a syphon. This way, as the motor drains its main tank, the syphon will transfer gas from the auxillary thank into the main tank.

Other than that, you could just give your neighbours idea a try... You would probably find out pretty fast whether it works or not.

Something isn't making sense. If, as you describe, the carburetor is above the gas tank, then an electric or mechanical fuel pump should be present to feed fuel. As such, the fuel pump will effectively limit excess pressure and things should work fine. However, most small horsepower engines that I've seen are gravity feed, e.g. the tank bottom is above the carburetor, negating the need for any form of fuel pump. If that is the case, the bowl valve could theoretically be overcome by excess head pressure from a massive fuel source and cause flooding, but I'm still dubious about that end result.

My concerns about the arrangement are proper storage and venting of any fuel container that will be subject to direct sunlight, heat, etc. and connections which preclude fuel loss and potential of fire.

If the carb is above the gas tank, the best way to ensure success is to mount the big tank with the feed tube between the two. If it does have a pump, You can also set a gas tank on the ground, run a piece of rubber tubing to wherever the norrmal gas tank hookup is, and use that instead. Make sure it's a vented tank if it's out in the sun.
