I have to fuel pumps.....
I have a mechanical fuel pump and a in tank pump. They run at the same time. It wont hurt anything will it? It will just give it a little more pressure, right. Just found it out today.

If the in-line fuel pump is stronger than the in-tank one, then it might be putting a strain on the in-line pump. If it's the other way around, I don't think it'll hurt anything, but I doubt you'll get much higher pressure than the weakest pump.
