Has anybody ever seen a lift pump leak externally? I replaced it in 2018 and the truck starts and runs fine, and I don't have oil getting into the crankcase.
There is a small amount of diesel dripping down off the bottom of the engine, and I know the injector pump is leaking (saving up for a replacement pump/injectors in the next month). But it also looks like the lift pump itself is leaking from the crimp at the perimeter of the housing. I cleaned the pump with degreaser and sprinkled baking soda on it, and after driving for an hour its still dry on the top but most of the baking soda has been washed off the bottom of the pump and it is wet with what seems to be fuel. There is no obvious dripping leak with the engine idling, but the engine crossmember is also soaking with fuel after driving for a couple hours. So it has to be coming from somewhere.
I'm planning to change the pump tomorrow and see if the leak stops, but was curious if anyone else has had these leak externally. Its kind of a pain to change them, and I was hoping it would last more than 4 years...
