waiting to hear from the dealer that they have gotten the part. will post the part number as soon as i get it installed on the truck. . It was funny though, when i took the truck in for testing, the "knowledgable" mechanic told me the truck would not run if the lift pump was not working. When he brought it back to me and said the lift pump was bad and they had to replace it, i just kinda smiled and asked if i could drive it till it was fixed and he just said "yea" and turned and walked off! gotta love it!
