LS Swap,Gas gauge seems screwy LOL

OK guys, went for a 15 mile test run today with the car. I noticed the gas gauge seems to be erratic. I put in 7 gallons of gas and it read 1/2. Didn't think much of it. As I was driving it read FULL. 5 minutes later back to 1/2. I'm using the Classic Instruments fuel sender with the Correct Ohms etc for the gauge. This is with a NON vented cap. Any ideas ??

Sounds like you are loosing your in tank sender ground. You drive and all of a sudden you are seeing it read past full?
Check the sender ground on the passenger side rear tank strap location. It may need a star washer to make good contact.

Checked ground, all was tight and secure. Good contact too. I should also mention I'm using Vintage USA gauges. Hmmm.
