I own a 2002 Dodge RAM Quad 1500. Recently I had a squire, chipmock, whatever eat away the top of the check valve on my gas tank. There are two check valves that are plastic and glued to the tank. The one in front is a light brown color with the number 3481. The check valve towards the back is black in color and has the number 3401. The entire 1/4" port is chewed off the black check valve. Rather than replace the entire tank does anyone know if there is a like replacement for the (black) check valve. I know they are roll over vent valves that are part of the EVAP system however I don't know what the difference is between the two of them and can't find a part number nor source of purchase. In Maryland we are stuck with the bi-yearly Maryland Emmisions test. I need to find a solution before the next VEI test comes around. Does anyone know of a part or subsitute part that can replace this valve.

 

Welcome to the site. I moved this thread to the third generation Ram section,

These tanks do not have replaceable check valve unfortunately. They are serviced and replaced as a unit. You can click on the link and download the Service Manual from the links in my sig for your truck
