Use in tank electric fuel pump to empty tank?

When I sold the engine and trans from my 68 Barracuda, it happened suddenly and unexpectedly. FABO guy looking for a good 318. I answered his wanted post and boom, engine and trans gone the very next Saturday.

That left me with about 15 gallons of premium in a car with no engine. I thought I'd siphon it out and burn it in my everyday driver. So I stuck a hose down the filler and started sucking. Yuck! Worse than Bud Lite and no joy.

Thought about it for awhile while staring at my empty engine compartment. I stuck a 5/16" I.D. hose on the steel fuel line that terminates on the front frame rail and put the other end into a 5 gal gas can thinking it may drain out. Nope, needed a push.

So I took a square shop rag, folded it in half, then half again so there were 4 layers. Then I popped the cuda quick release gas cap, and covered the filler pipe with the 4 layer shop rag. I then took my air hose with the blower tip and pushed it against the rag so it was slightly depressed into the filler neck. The cloth gave it somewhat of a seal without a lot of pressure. I gave it several short blasts of air to pressurize the tank and that started the siphoning process at the front. I left the gas cap open and when the gas can was almost full, pulled the hose from the can and raised it up, like top of the cowl height. That stopped the siphoning. Took me 3 times to empty the cuda tank. I just poured them into my Subaru and Jeep to burn it up.

Sounds weird but worked great. I was going to post it in the tools and tips section but never got around to it.
