Tank cap will not tighten due to bad threads. I tried 2 new caps and had the same results. Will not but again.

Being able to see through the casing clearing is definitely a step up from what I had before and it came a the sensor, which is a major bonus

It came with a bad sensor. First day my clutch fan wouldn’t go off, spend extra 80 dollars on fuel that day and wouldn’t read when coolant was low. Ended up using my old sensor.
