Stock fuel pump with 42lb injectors
Well finally the 6.0 is going in to replace the 5.3 Tomorrow. The new Cam, headers and Supercharger is ready to go in. Im now concerned with fueling. Does anyone know what the stock fuel pump is capable of with the 42lb injectors. Pleas advise.
:confused: |
Mine is still holding with a mild heads/cam 5.3L and 100 dry shot on 42lb injectors. However, I have a little over ~108K miles on the pump so I plan on swapping it out with a Walbro 255 for safety's sake sometime in the near future.

I had to put a Walbro 255, stocker couldn't keep up @ 5psi boost and 44# injctors.

Vortech inline pump to keep up with my truck and a good $40 inline 255 pump on my Blazer.
I'm a big fan of the simple inline pumps. LOL |
