[QUOTE="mike_belben, post: 102315, member: 14096"] Mechanical injection pumps use a plunger and barrel array in a common galley pressurized by the lift pump. O-rings keep the fuel oil from getting into the lube oil that is pumped in to lubricate the iniection pump cam and roller, bearings etc. If the O rings fail itll end up draining back to the pan. Pull the lift pump and put the rated fuel pressure amount of air into the outlet nipple. If it leaks youve got a bad lift pump. If not, probably injection pump. [/QUOTE]
