Elshaunero White 5pts Overall, I really like this photo story. Since I am considering doing something similar with my 88 K5 Blazer, I have questions about details that were left out. What specific fuel pump did you go with, and why did you replace your stock tank? What specific motor mounts did you go with for the LS motor? What does "HRR" stand for? You mention attaching the two heater hoses to the water pump, but what are they attaching to on the other ends?
