csx4910 With straight race gas or unleaded straight gas you get 5-8 years. Again it's back to the methanol eating evrything up at a faster rate.
If you have good pre filters to the pump or pumps, just keep an eye on it. You will need to replace the foam t some time.
It helps if you drain the fuel over the winter. ERA fuel tank has 8 bolts and 3 connections. easy to drain and drop in about 10 minutes.
I have not put the foam back in my tank after installing new fuel pumps in tank. Has long as I carry 1/2 tank of fuel no problems racing. I don't feel any real weight transfer from right to left on turns. I do have the double gas cap setup for the car.
Take out the foam and drive the car, there should be 2 -3 baffles inside the tank that will help control fuel sliding around in tank. Rick L.
