P Pump Gurus, i need your help, Fuel leak...
Guys
poppin the hood on my truck today for the weekly fluid level check, i noticed two leaks, one was a coolant leak, (not the HG tho, so big sigh of relief) and the other was at my P pump..
The leak is right under fuel line number one, looking from the driver side of the hood towards the P Pump, At injector line number one (closest to the front of the truck) i noticed and saw a small stream of diesel fuel running all the way down towards injector line 3 then dripping down.
I tried tightening down the injector line, then undoing it, and retightening it again while the truck was running, and it was obvious that the line itself wasnt the problem.
I am now looking down my P pump and seeing that there are 2 9/16 size nuts holding down something, and thats where the leak is coming from. I tried tightening these things and they were already tight, no leak stoppage..
My question is, under those 9/16 bolts, what is house? I know that the DV goes into those barrels, and i know that they have gaskets, now my question is, did a DV gasket go bad on me? or is there a gasket underneath those 2 9/16 bolts that went bad?
Im hoping i dont have to do a complete teardown to fix this leak, guys please help me...
Thanks in advance!

Thanks Ok bill
I found something on the cummins data base that might be of good assistance...
http://www.cumminsdatabase.com/read.php?id=182
Going down to the picture that says delivery valves, i see a green thing that appears to be an O ring, Just wonderin if im right on that, I also see no gasket where the bolts seat the barrel base(?) to the actual pump housing.
Since im not seeing a gasket, nor am I seeing RTV or any other kind of sealeant, im starting to think that Little O ring might be a culprit, any idea how hard that would be to replace? or must i take my truck to a reputable diesel shop and have them fix it?
Ive done DV's, but im not sure i can stomach this one.. any ideas?
Thanks!
