    I'm planning on up-grading my in-tank fuel pump. I have found plenty of 255lph units but I was wondering if any body knew where I could find a larger one. Thanks in advance for your help.

      I believe the 255 is the biggest direct replacement fuel pump they make for f-bodies. If you go any bigger than that, you have to change the pick-up tube and the fuel lines, because I don't believe they can handle any more flow than 255.

        A 255lph pump is good for over 600HP. If you need more than that, consider a single outboard 340lph pump, or do what I did and run a 205lph intank, and another 205lph in parallel, mounted outboard, off a sump in the tank. Good for 1,000HP. And that's through -6AN supply and return lines... not much larger than the stock supply line.

          Thanks

          I thought the 255lph unit was the biggest, but I had to ask the people who know to be sure. In-tanks are a pain and I really only want to do it once. One more question, can a SC be ran (at a reasonable PSI) with out an in-line if lets say your useing a 255lph in-tank? Thanks again.
