I never pulled one on a stock system but I think a good way would be to remove the filter outlet hose and push on a 1/2" clear vinyl hose with enough length to go over the fender to about 6" from the ground and use the primer pump to start a siphon. Once started I would flush the hose by flowing a couple gallons while shaking the hose to clean it well then catch the sample after rinsing the bottle and both sets of threads a few times. Fill the bottle to the bottom of the threads and immediately install the cap. This is also best done on a NOT so dusty day with clean hands and hose. After a rain is perfect. Sampling tecnique is everything if you want a representative sample.

Good advice from a bear. I just posted the results from my second test. I don't believe you can flush too much. Do not take your sample out in the drive way or any place the air is moving around a lot. If need be, get some one to pump the primer to keep the fuel flowing. I pumped a gallon into a clean jug to get started and then used my oil drain pan when I started flushing the bottle, lid etc. Later! Frank
