I keep getting the check engine light with a code o P0442, I have changed gas cap along with the purge valve under the hood, and still keeps throwing the code. I went and had the local dealer do the smoke test and they informed me there was a leak in tank just above the filler hose, I dropped the tank again and pressure tested the tank with air and used soapy water and couldn't find any leaks or small holes, inspected all lines and couldn't find any visible leaks or holes any ideas on what else I could check or what the problem might be? The dealer told me I need to replace the filler pipe and tank at a cost of 1600-2000 dollars. really appreciate any help.

WELL, YOU SAID THE SMOKE TEST SAID IT WAS IN THE FILLER ABOVE THE TANK

I SORTA FIGGER THAT'S WHAT MIGHT NEED THE ATTENTION?

AS A HILLBILLY TEST

CAN "YOU" TAKE THE FILLER LOOSE FROM THE TANK???

CAP THE TANK'S INLET WITH A TIGHT FITTING RUBBER/ VINYL CAP, OR SOMETHING SIMILAR OR HECK! JUST DUCT TAPE THE TANK INLET COMPLETELY AIR TIGHT SHUT

CLEAR THE CODE, DRIVE A WHILE (INSURE YOU DON'T EXCEED YOUR FUEL VOLUME!)

IF THE CODE DON'T SHOW, THIS MAY VERIFY IT'S THE FILLER THAT IS THE PROBLEM

I CHECKED 2 ONLINE/ AND LOCAL AUTO PARTS STORES (LIMITED TIME ON MY PART) I DID NOT FIND THE FILLER WITH EITHER. OTHERS MAY HAVE IT, YOU MIGHT CHECK ROCKAUTO.COM OR OTHERS. EVEN THE DEALER MIGHT BE A FINAL OPTION.

HAVING SAID THAT

LET'S LOOK FOR A QUALIFIED AND REASONABLE SHOP TO INSTALL IT, IF YOU CAN'T DO IT YOURSELF.

HERE'S A NATIONWIDE WAY TO FIND THE RIGHT PLACE! SEE MY ANSWER IN THIS LINK

I FEEL SURE YOU CAN, AT MINIMUM, CUT YOUR COSTS, BY LEAVING THE STEALERSHIP OUT OF THE EQUATION!

GOOD LUCK!
