- - Fuel tank vent puking gas !! (https://www.lateral-g.net/forums/showthread.php?t=14688)

I had to have Rick's fix my Nova tank several time's..This last time was finally the solution.

At first my vent was super small like Gregg mentioned and the fuel would just expand and climb out, no matter if it sat in the garage or I drove it.

The final stage was to make the breather bigger so now I have two big 3/8 port's that face forward at the top of the tank. Inside they have big long tube's that run the length of the tank so it's harder for fuel to climb in there.

On the outside I have the two tied together from a 3 way tee then the hose climb's to my trunk where a canister sits from there it climbs back down under my car and vents outside the car..

I drive the car in 110 degree weather and have had zero issues with pressure again.

I do want someone to make me a vapor canister but has not been a priority.

Greg's right: putting the vent in the trunk is a concern. If one can find a way to properly vent the tank and keep the plumbing on the outside of the car, that's always preferable.

However, on some cars, there's just no way to do that unless you live with leaking gas caps or a vent directly open to the atmosphere, and that has safety (not to mention environmental) issues too.

I would also observe that typical pressures within the vent plumbing rarely goes above 2 psi, and is usually at zero psi. Using quality plumbing rated at 100+ psi, plus doing consistent leak checks can mitigate that risk.

Doing it this way isn't as good as keeping it all outside the vehicle, but it's better than dumping gas on the ground during typical driving.

100% agree. I have a Rick's Tank and was extremely dissatisfied with how the vent puked all the time. I was even more dissatisfied when I called Rick's Tanks and couldn't get an answer on how to properly vent there tank! It's a waste of gas not to mention more of a hazard than what I built. Can you imagine someone flicking a cigarette on the gas your car just puked out? There are no fumes in the trunk of my car and I built the canister from high grade stainless steel and used quality Aeromotive gas hose. I would be amazed if there was any pressure in the vent hose. Maybe I should have included how I plumbed all the lines to the front of the tank, but that was my mistake.

I've been driving this car for almost 20 years. It's my daily driver and it has to work and be reliable. I wish I had the time to do everything the way I want to, but I don't.

I figure primer is a color too.

Nice chevelle! Primer IS a color!:D

I figure there's no difference in safety compared to a plastic fuel cell in a trunk. I do appreciate the criticism and I'll probably remake a canister that fits on the inside of the bumper. I wonder how small the canister can be and still be effective...

Having said that -- a canister tucked into the bumper is a great idea! Maybe fill it will charcoal (not the barbecue kind -- the kind you'd buy at a fish store that they use for filtering the water). That would kill any fumes when parked in the garage.

I have a question.

Does anyone else think a charcoal canister with proper fittings,lines and instructions should be included with their $1200 tanks? Not just vented catch can, but charcoal filled one. Spilling gas on hot pavement at triple-digit temperatures is downright dangerous . The nasty gas stink in garage ,gas spilling on expensive paint job is not cool either. I think it's a serious liability issue and should be addressed ASAP.I don't mean to throw Rick under the bus, but he suggested to attach a hose to vent tube ,loop it twice and route it inside the trunk. IMO that is not a solution,I don't think anyone wants their interior smell like inside of gas tank and have headaches every time they drive their car,especially on long trips.

Yep, I agree

I know that Prodigy Customs has some inventory of Rick's Tanks, and that they also have inventory of my vent systems which can be offered as an option for those tanks.

Since you jumped on. On my latest project I am doing a carb'd LS1 with an external Fuel pump ( all edelbrock ). I am torn and not sure if a custom tank is the way to go.

Your thoughts John.

ps - that car is being built to be driven and enjoyed. The chances of me finding time to go out and race the car is slim. But I do plan to do the autocross at the GG Events.
