Been working on our old fire truck for a while now and we have developed a new leak somewhere near the water pump that I can't tell where it's coming from. I have had the pump off and cleaned the area up real well and put on a new gasket. While running and under pressure, about 5-10 min after cutting the truck off I get a drip/stream for a minute or two on the front of the block near the pump. I have felt around the pump/block union and it is dry. Am I missing a weep hole somewhere or have I completely lost my mind? I did not replace the back plate to pump gasket so that is a possible but I'd think I would feel it when checking the area under the pump. Anyone have any suggestions?
