I am in the middle replacing the water pump on my 99 7.3L F250 and I noticed the impeller blades on the new pump (AirTek) slightly touch the pump housing. The impeller spins fine but on the old pump I pulled off the truck there is a gap and no contact. Do I need to return the new one or will it wear into the slight gap?

I'd say get a new one. I bought a Ford Waterpump last year, and I too had just a bit of impeller rub on the housing. I also noticed that the seal would squeal just a little bit when I started to turn the impeller.
I took the pump back, and the dealer replaced it no questions asked.
Good luck in the changeout!

Something is not right with that particular pump. A couple of years ago I bought a new OEM pump from DIESELSITE.com to have a spare and it was a good deal at the time. I still have it in the box in my shop have not needed to install it . The impeller on the new pump I have does not rub the housing. Take that one back and get another, I wouldn't install that one. 106
