I have codes P0456 and P0442. I had a smoke test and diagnostic done when the P0456 came on and it was written on the paper as "LEAK AT VENT PIPE AT FUEL TANK". I do not have so much knowledge about cars besides the mechanic telling me, I need to change the fuel sending unit because it's a small leak. This is an ongoing problem as we haven't driven the car up until now to try and fix the problem and the P0442 code came on as well. We didn't get a smoke test or diagnostic for that one.
I would like to buy the parts and have someone I know who is a mechanic change it for me. Would the P0456 code just be an hose change rather than a change of an fuel assembly unit? I would just like to know possibilities. Does this codes coincide with each other with the fuel assembly pump? Is there any other causes of this problem and could it be located elsewhere besides the fuel pump?
have the same problem?
