1st welcome to the GWOF. Great site with good people & info.
I changed the fuel pump on my 1500 over a year ago. I found an aftermarket on Ebay & it worked great. This is the guys username I don't know if he still has them or not. rperez0122 The kit he had has all the intructions needed to complete installation & worked out great. I will tell you that there was a load of rust & crap in the tank that I had to flush out 1st.
Good Luck.
