Fellow "A" body maintainers, Racking my cranium trying to figure out this fuel gauge anomaly. Needle moves ever so slightly to just above the "E". Here's what I've accomplished: - Installed new tank/sending unit and got that slight movement above "E" -grounded power lead at tank and gauge will peg out to full and return to empty. That tells me wiring up thru the instrument cluster is good. -Removed sending unit. Rheostat ohmed good from empty to full. 3ohms to 84 ohms -With unit out of tank and grounded I manually moved float and gauge read empty to full. -Re-installed sender and grounded as per Mopar and with half tank fuel had no response to gauge movement. -tried all different variations placing ground in different locations. All continuity checks were good. -Ensured I had my engine to firewall ground intact. -Ensured cluster was grounded to dash. - Manipulated ignition switch to see if any help but none. -Tried a second sending unit....same result -Just for giggles, I replaced the volt limiter on cluster...same result. -I turned the sender upside down in the tank and it read full on gauge. Re-installed it right side up and no reading. - Could it be a baffle in the tank is installed incorrectly? Need you guys to help me right the ship.
