This is a plague of the 370z, for the fuel level gauge to be off by around a 1/4 tank... often it will bounce between 1/4 off and correct, once or twice a tank. Or for some it just stays wrong, never reading entirely full.

Very often, it happens immediately after molesting the fuel pump housing for modifications.

I am not sure the source of the problem, I would need the car here to diagnose it. But dont feel bad, it is a common occurrence after fuel system work.

One suspicion I have, is the in-tank siphon hose slack interfering with the fuel level float arm travel. But I have in the past run into slightly worn level sensors that do not read correctly.
