Default help with fuel pump issue.

long story short I just finished installing a new TRE performance fuel pump. i did the trap door and did it my self. drove fine for a day then it stopped working, the pin connector was loose (my bad) fixed it and it worked like a charm. drove another 300km and suddenly it stopped today!! guage was pointing at 1/4 it felt like it ran out of fuel. i added fuel A LOT of fuel and its still doing the same thing!! it sputters and misfires like it has low fuel. all connectors seem fine. what do i look for? i took the pump out twice, am ready to lit the car on fire now

do i tow her to a garage? or take the pump out again in the middle of the street? i dont have a pressure guage. could it be one of the lines? or vaccum? ideas please!! thank you.

In tank leak. Check the hose clamp tightness.
