I had to replace the fuel sender unit on my 2000 Boxster base because of a leak, fuel gauge has always indicated correctly. Before doing the job tank was almost empty, low fuel light on, gauge sitting on top of the lowest line.

Replacement was smooth, i did my best to ensure the float is not obstructed by any fuel lines inside the tank and also that the top of the unit is lined up correctly (arrow on top aligned with the 3 lines on the fuel tank). Once buttoned back up, all worked well, gauge was exactly in the same position as it was with the old sender unit (bottom line on the gauge, low fuel light on).

I filled the tank up completely (took 14 gallons) but now the gauge indicates exactly half tank.

Could this be a faulty fuel sender unit or the float is stuck on something?
From the research i did there is nothing to reset, nothing to adjust on the unit prior to installation.

Any thoughts would be appreciated. I was going to drive it and refill again and see if that helps, otherwise i might need to get in there again.

Thanks,
