Hi I had taken the bed off my ranger and I had noticed that the vent hose connector had a hole.

 

Are we supposed to guess what year truck this is?

 

clean the area around the hole and get jb weld for plastic and patch it , you will want to find what was rubbing on it first so it doesnt happen again

 

Fuel tank vent hose. Looks like a mouse chew. Clean the area and patch with two part epoxy.

 

If the JB weld for plastic doesn't work, then scrap yard or dealer.
Rock Auto doesn't list anything, or at least I couldn't find anything.

And definitely a mouse chew, you can clearly see the little buggers teeth marks.

There's this too, but kind of expensive.

Auto parts stores sell a two part epoxy that is in a putty form it will do a better job here because jb weld is thin and will run down in to the tank.
