Rollover vent valve
 

Has anyone replaced the rollover fuel vent valve on the top of the fuel tank? I broke the valve stem removing the tank and plan on installing a new one tom? Tips ? Steps? Do they just pop out do they need to be sealed...Any help appreciated

There is no replacement part, the whole tank needs to be replaced unless you can make a miracle happen with JB Weld or some other epoxy

Nope picked up the replacement for $30 bucks pretty much universal ....pryed the old one out and slowly installed the new one by tapping it with a rubber mallet

i know this is an old thread but what year was the blazer as i have a 04 and i think the vent valve is bad. its a plastic tank and i cant find the valve anywhere

its on the front and top of the tank on a 4 door, and they do make the replacement part (GM actually still does)and it runs about 15 dollars on RA.

i dont have a 4 door i have a 2 door with plastic tank and no the one that fits the 4 door will deff not work on a 2 door with plastic tank.

picture?

picture of what?

THIS IS NOT MY TANK BUT STILL THE SAME TANK.

thats definitely a different part, 4 Doors have a single stem valve.
