Was told by my machanic and parts manager at GMC dealership that the 6.6 Duramax didn't have a lift pump. Have a 99 H1 that does but it's a 6.5. It has set awhile and I have been trying to find a filter housing for weeks. Went to the dealers parts man and we went through every duramax configuration on the system, the only thing close was a Kodiak 5500 but the primer pump is straight up and on the H1 it is angled towards to front. Thanks
