I've got a replacement tank on salvageV6 my daily driver.
Pan baffle is what is in it.
Works fine, never starved out and it's been run hard with the little yellow low fuel light on once in a while. ;)
At the track the car usually has 7-12 gallons in it.
Baffles are way over-rated.
Had to buy and solder on the neck to the tank however so that may be an issue for you, make sure your tank comes with a neck.
