What pump did you use on your recent LS L33 swap? Stock 4.3 vin W pump? It's what I plan to use with my LQ9 6.0. If you're going racing with bigger injectors I could see needing something different. On a overpowered DD I think the original will be fine. If it's working as it should.
oldeerslayer your thinking about my build. I built a 95 6.0 for a weekend toy and I’m working on a boost 5.3 build now. The OP doesn’t mention anything about a previous build. OP I used a Racetronixs 255 lph in tank pump on my 95 build.
