Fuel cutout solution

[AZReason]

When I first tracked my Elise I could run the gas gauge till it was down to one pixel line (not one bar) of gas without cutout on track. Then I needed more gas to keep away the cutout. I decided to have a smaller fuel tank made. I bought fzust’s fuel tank to have made into a better tank. After I removed my tank I looked inside. I noticed that the sealant around the metal panel that is spot welded inside the tank was no longer sealing the “collector” section of the tank. I changed my mind with inspiration from a post by kverges. I decided to reseal the metal panel. I removed the old sealant, prepped the surface and resealed it with a fuel proof sealant. After reinstalling the tank I added one gallon of fuel to the car. I noticed that the gauge only indicated one pixel line of fuel. This might explain why some people run the car till it shows completely empty and can only add 9.5 gallons of gas. Once again I can run my car to one pixel line of gas without cutout on the track. Check the for sale section for a stock tank for sale since I don’t need fzust’s anymore.

An aviation mechanic friend of mine highly recomended the following:

PRO-SEAL TYPE TANK SEALANTS from Aircraft Spruce

However, something like quicksteel (a fuel-proof epoxy putty) might be easier to apply and can be found at your local auto parts store.
