My trucks running a little rough at times, these are the only codes it's showing, i kno p0453 code is fuel tank pressure sensor high. P0460 fuel level sensor circuit. I don't kno where to start.thanks

 

I don't think your codes have anything to do with it "running a little rough at times"
Check the wiring harness to the fuel tank,connectors ect
Could you be more specific about "running rough" idle/diving/cold/hot?

 

When truck warms up it idles rough and rich (black smOke when I rev up) was getting o2 sensors codes and running rich codes but they went away after I replaced o2 sensors, now I drove truck for 2 weeks and I'm just getting this codes. I'm getting about 13mpg it's a reg cab 1997 4.2l f150 4x4 5 speed 109xxx miles

 

The po453 could in fact be high pressure in the fuel
tank,but it,with the fuel sensor code I am guessing wiring harness.

 

Here is a link for the po453 Moss
