i have a fuel cell in my car,i have a question about the rollover vent. mine has an internal check valve, had a cap on it when i got it. should it remain capped? i removed it,and i get a fuel odor in the car. i have re- capped it. any thoughts? :3gears:
I have mine vented outside the car. Several companies make the vent tube. I made mine myself out of aluminum. Rolled it into loops, and out the car the fumes go. Better to smell meltin' rubber than pass out from gas fumes,lol.
Isn't that the vent line fitting? Fwiw - I ran the fuel cell vent line in my roadster up as high as I could go in the trunk then back down through the floor. Worked fine except for a mild gas smell in the garage after the car sat overnight. The smell would about knock you over when you were under the car in the vicinity of the vent. I left the 'up as high as it would go' bit of hose in the trunk and routed the vent line into a charcoal cannister. A nice small one, steel bodied that came off a Toyota pickup. Bout circa late 80's - originally installed in the left front of the pickup engine compt. From there the line went from charcoal cannister to an Earls inline fuel filter. The model with stainless screen. Thinking there was the screen in the filter would act similar to an acetylene flashback arrestor. The line goes from the 'arrestor' to the air filter where it vents into the non-filtered air area. The big worry was a backfiring carb could create a fire problem. It works fine and best of all the garage doesn't have gasoline fumes in it.
At the very least put a filter on the end of the line to prevent dust from being pulled up into the fuel cell.
Dirt and debris I have a small K&N style filter clamped on the end of my vent tube. It keeps the bugs and dirt out of the cell. Just my $.02 Jim BTW Dave has it right!
