Okay heres what is going on I had the fuel level sensor die replaced it and then started getting the ses light code reads mass vacuum leak. now heres whats different when I fill it and drive some the light goes off and comes back on when it drops back below 3/4 of a tank. I replaced gas cap thinking that might be it but no made no difference. Any clue any one else have this problem?

Thanks

Bill

what is the code?

 

[mrbill65]

p0455 if i remember correctly

That's an EVAP code so ether they left a line off or one the gasket are bad.

crazy thing when the temp outside drops in the low teens the light goes out agian. Last night we had a low of 13 and the light went out with less then half of tank what lines should I look at and what gasket would be bad?

The EVAP system monitor not run if the outside temp is below 40F.

Who replaced the sending unit? Any hose that was disconnected darning the replacement. The gasket for the sending unit.
