Well, that would work. All we would need to do is find some high temp hose that would also withstand the disolving properties of oil. Just put a hose clamp on a hose on the pickup tube. Hmmm... Interesting. What does he use for the weight at the end of the hose, and, would that weight sliding around on the oil pan cause shavings to scrape off? Maybe a teflon coated weight.
