there are no orings leaking more than likely. In fact the only oring is in the head of the old AC injector. IT is usually oil from the valve cover leaking in to the copper tube hole from the valve cover side and coming out of the copper sleeve the injector sets in. Diesel fuel will not seep if the ring is leaking, it will pour. The tops of the injector if the old AC type can leak at the drip line and the later bosch can leak at the banjo bolts on the drip line. We have many injectors brought to us needlessly. The story is always the same - my inj is seeping fuel - and the problem is always the drip lines or the valve cover gasket.
