I can't imagine why anyone would put that pump where it is right now. A high pressure FI system needs the right install. Electric pumps are great at pushing, not so great at pulling fuel, especially that far away. Electric pumps work best if they are either gravity fed, or in the tank. In any case, you need to have a look at that pick up, and then rectify the fuel pump situation. Here is the Sniper installation instructions, https://documents.holley.com/199r11031r.pdf Have a look on page 5. Whoever installed that fuel pump didn't read the manual.
Since I already have the sniper EFI I think I might just get the holley in tank pump module for it. I'll kill 2 birds with one stone by having the pump in the tank so I can't hear it and I'll get a new fuel sender which I probably need anyway for the gauge to work again.
