HPOP lines leaking?

I was just replacing the 2 o-rings on my fuel/water seperator and noticed that the two lines coming off the HPOP going to each head look like they are leaking (by the pump). The leak seems to be coming from where the hose connects to the part that screws into the pump. Is this a common problem? Is this small amount of seaping hurting anything if I dont replace them right away? Any info would be appreciated. -Thanks Jim

Is it leaking between the pump and fitting or between the fitting and hose fitting?

A leak between the pump and fitting is quite common. There is an o-ring that seals there and they will leak on older trucks. A leak between the hose fitting and the fitting that screws into the pump is not as common. If it is a little dust collection then that would be considered "normal" If the engine is wet with oil below where the leak is then you should be thinking about getting it fixed.
