I've got a puzzling question to pose to all you intelligent boxster DIY guys out there...

My boxster never reads 4/4 when I fill up. The best I get is a hair over 3/4 full.

I replaced the instrument cluster with a brand new one (needed it anyway for a burned out LED segment). Didn't fix the fuel indicator.

Hans (mechanic) tied off the fuel lines inside the tank to keep them from getting in the way of the sending unit's float switch. Didn't fix the fuel indicator.

I replaced the fuel sending unit and calibrated the unit. Didn't fix the fuel indicator.

What else could be causing it?
