2002 2500hd (gas) fuel pump problems

[Hillger 189]

Well I replaced the fuel pump in my 02 2500 and while I had the bed off I decided to drive it down the street to the car wash to clean my chassi since it was visible and while I was driving I noticed a weird ticking that seems to go up and down with my RPM's, even when it shifts the tick stays with my RPM's. But how ever when I'm in nuetral and rev up my engine it dosnt do it, even if I'm rolling already and put it in nutureal and rev it it stil dose not do it any ideas guys????
