When you guys have a full tank of gas on the 95,96,97's how full does your gauge read? Does it touch the "F" post pictures if yo got them.

This is a 97 4D BTW

 

trad444, welcome to the forum. There is a wealth of info on here for most anything you could want to know. Here is a link to about 100 threads involving the fuel guage.

BTW I'm always on E, always staring at a fuel warning light, and most of the time I remember to re-set my odometer...

 

agreed - im a odometer re-setter as well. Working gas gauges are for poo heads, lol j/k. anyhow, the chevy gas gauge, if i recall, is measured in ohms resistance - 90 ohm full tank and 0 ohm empty. so that being said, the resistance of the sender could just be old and not sending 90 at a full tank.
