Going to do the Duralift pump. I've seen two part numbers with two different psi's on here. One puts out 9-11 psi while the other puts out 4-7 psi. My truck is a 91 7.3 with a Banks turbo on it. I know the stock mechanical pumps are around 4 psi. Which of the two e-pumps would be better in the long run?

 

Most are using the 7 PSI pump that GenLightening has been selling however either one will work.
here is a link to his thread on oilburners about this pump:

There are several threads here about them on here if you do a search.
Here is a recent thread on the subject:

I got a lot of info from searching but nothing that ever said which pump was the preferred one.
