Check the seal on the underside of the cap, you might need to replace it.

This error code p0457, just popped up and I have a diagnostic reader. After reading the code it said it was a bad gas cap but the cap is fine. After further looking into the problem i noticed a small fuel...

The bad gas cap is related to the evaporative emissions what happens is the gas that is not used in the engine return to the tank via the 2nd hose. The tank is pressurized very lightly by this and a sensor detects whether or not the air escapes. So if the cap is loose or there is a leak in a hose the code will set. Since you also have a leak I would start there first. The straps most likely are not cutting the tank the epa would have a fit. Most likely the the gas is coming from above the tank and working its way down the straps. Lowering the fuel tank requirs raising the car quite high. If you are able to inspect the area and reach it I think the leak would be in the gas lines above the tank. Or from the filler tubes when you fill with gas. If you can see the gas leak but are unable to reach it take it to a shop. This may fix the light if not a shop with a (smoke machine) will pump smoke into the system and search for air leaks that way. Good luck .

Engine light on code is po440

P0440 Fuel tank vapor emission problem.
Could be as simple as a leaky gas cap.....or a missing gas cap.

Have you purchased gas and left the engine running as you filled it?
That will turn on the light too.

The P0440 is one of the most common codes and pops on the dash of 50% of cars on the road as they get older on a weekly basis.
An extremely small vapor leak on the fuel system will pop this code on.
Most of the time.....this code cannot be fixed......the answer is to buy a cheap OBD2 code reader and remove the code yourself every time it pops on........and on the 50% of cars with shows up about 2 times a week.
When the engine light is on,you will loose 20% of gas mileage and has 20% higher turn it out!
Some cars will not go into overdrive with this light on.

you have to understand that there is a leak in the system other than the gas cap for the evaporative system. The system needs to be professionally closed, and smoke introduced into to find the leak, and a through component check, eg.. purge valve vapor canister vent solenoid all functioning correctly

best bet would be to get a new one also remembering how much the dealers charge for there products i would go aftermarket threw partsunlimited, cruiser, or Tucker rocky but the dealer still has to order it for you, all have great quality products at cheaper prices than O.E.M replacements unless your still under warranty.

Evap leak in fuel

Remove the gas cap and re-install it making sure that you hear it click several times. What your evap leak could be is the gas cap allowing gas fumes to escape. All it takes is a .040 leak to turn on the engine light. If it persists you'll have to have the emission system smoke tested. What happens is the system is literally filled with smoke and the leak will be found by where the smoke comes from.
