Stratocaster infinity indicating double the fuel flow

[Dusty]

I have a Stratocaster infinity fuel flow in my Savannah S I’ve just purchased.
I had to replace all the fuel hoses and now the gauge indicates a fuel flow at double that it used to.
Before, it was slightly lower on the outgoing side, but I changed that for it to be slightly higher, exactly as the photo that is posted under installations.
It worked perfectly before, what might I have done, and how do I get it back to normal.
