I think I am out of warrantee on this 70,000 on my truck. Looks like the pump is leaking real bad from the top of the pump from what I can see. Is there a seal up there I can replace or what will it take for me to pull this thing. I don't have alot of down time here as I need to hit the road again. Are they rebuildable and do they sell kits or do I need to buy a new pump from the dealer ? Also, If I need to buy a new pump am I better off just having the dealer replace the pump or go elsewhere ?
