However, in my experience when they fail the engine loses fuel and shuts off. You can also remove the contaminated oil by removing the oil cooler lower line and blowing air through it. Generally the Kubota engines typical in today's Bobcats have a single injection pump but I have never seen a Deutz B4M 1011F engine with a single injection pump. If you think your lift pump leaks all you have to do is take the hose coming out of it and plug it, then squeeze the primer bulb and see if fuel still flows.</p></blockquote><p></p>
