Unlike a standard fuel tester, which can fill after just a couple of sumps, the MultiSump can handle eight to ten samplings. With a stainless steel push rod, no-drip pouring spout, and a quick-acting drain valve, the MultiSump can be operated with just one hand. Measuring 7" high by 2-3/4" in diameter, the MultiSump Fuel Tester [1352A] is available for $24.95.
