Think that is the same part # as the VP I just put on my truck, (its pouring down rain or i would go check). What they told me is in late 2000 early 2001 there was a switch from a crank sensor to a cam sensor and it is a different pump. Dont know how true this is had a pump from a early 2000 truck and they look the same so must be internal, (holeshotholset should be able to answer this). Price was the same on both pumps but they said the one in question was a restricted part whatever that means. The core was 200. 00 less than the other pump.
