LS6 conversion - fuel pump question
Working on future plans and collecting parts. The question is regarding the fuel pump to support an LS6 with fuel injection. Is the an option to use an aftermarket in-line fuel pump rather that an in-tank style pump?

It can be done with an external but in tank is highly recommended. I have an in tank and added the external as a redundant when the in tank failed a couple of years back. After dropping the tank and waiting for the replacement pump to arrive I figured it would be better to be able to switch pumps and keep driving rather than be stuck on the road if I were to suffer a fuel pump failure away from home. Now I switch off monthly between the pumps to keep both systems alive and well.
The in tank pump has the standard sock filter on the pick-up and the external pump has a filter in line between the tank and the pump intake.
Both pumps feed to a common in-line filter and from the filter forward to the injection.

I agree, in tank is the better way to go, however I am running a inline external MSD pump. I do have over 7000 miles on this setup without issue, I have side pipes, so I cannot hear the pump run with the motor running, I hear the pump come on when I cycle the key, but after the car is running, I do not hear it.
