I need to get rid of it to put a catch can in it's place.
Do you just plug the lines going in to it after you get rid of it?

i took the canister out, removed the tubing from behind the motor and then ran a wrap around hose on the left side from the one open hole to the other. Yes one is bigger than the other, but hose clamps are wonderful items. I talked to rxtreme about this today after the races. I think he might remove his too.

Whats so bad about it that you want to take it off?

RXTASY1

Nothings bad about it. I just don't think it is a neccessary item to have on our cars. I need to reduce as much weight as I can and also I need to use that spot for a catch can so I can put my Jacobs box in the existing overflow spot.

How do you plan to ventilate your fuel tank if you plug up all the hoses?

Josepi

I don't think they mean completely blocking off the return lines...

If that was the case, wouldn't the tank then be under vacuum seeing that gas is being removed, no air in to take its place. Wouldn't it then be harder for the fuel pump to pump gas out of the tank?

Just wondering how things work...

RXTASY1

So am I the only one that wants to do this?

Hell, I did it weeks ago. No biggie, just smells like gas all the time.

You talking about an oil catch can? Where are you going to catch oil from? These aren't required on rotaries because the oil in the sump completely isolated from the rest of the engine, and we don't have blow-by like piston engines do. The charcoal cannister would be more useful to you. Who wants a car that reeks of gas?

RXTASY1

Yeah... I guess I should clarify this.
Since I posted this, I have installed a Haltech and I put all the sensors and fuse blocks in that area. Now I have to get rid of it.

Mine is just gone. All of the hard lines are open. I don't smell gas at all...

...except for that time my gas cap went bad. I changed the cap and I'm back to no gas smell.

Is it safe to leave them open? I just blocked mine, and the only difference is when i open my gas cap, there is a big swoosh sound. I was thinking about just running a vac line from the hard line to the bottom of my car.

MikeL

Mine have been open for two years.

The larger hard line that runs along the firewall from the cruise control area to the brake booster area is open on both ends.

The smaller one that runs runs along the firewall from the cruise control area to the brake booster area is open on the cruise control end and is connected by a rubber hose to a hard line that drops under the car.

Now that I know this, I'm gonna remove both lines from the car.

I was about to remove my upper intake last year because I smelled gas. I actually had the socket on a bolt when I heard a hissing noise. I found that gas fumes were coming from the small line. I could only guess that the tank was now pressurized when it had not been before. The only reason I could think that the tank would be pressurized is if the gas cap had gone bad and was allowing pressure to build. I replaced the cap. The hissing and smell went away.

If your lines are capped and your tank is pressurized, I think you need a new gas cap.

I hope this helps

I though there was only one hard line, that came from the gas tank, one line that filter out to the ground, and one that came from the engine. I gotta go look,

MikeL so ur gonning to remove all lines and leave everthing open? I have a new gas cap and it hisses when i open it, thats w/ all the ends capped.

"thread Ressurection" whooooooo.


Couldn't you tap your intake tube and just link the charcoal canister lines into the intake?

Just take the hose coming from the tank and shorten it so its behind the drivers area. that way no fumes can get in. basicly cut it off near the tank.

Mazda seems to think it was necessary.

It weighs 1.6 LB. Probably the same as your catch can.

The existing coolant overflow area? Not much air flow there. Best to put it near the front of the bumper, where the crossmember is.

Also, the charcoal canister is designed to absorb FUEL vapours. Simply open venting the line or plumbing it into the intake is pretty stupid and dangerous.

I relocated mine down out of the way. I needed the extra space for my intake but found no good reason to remove the charcoal canister.
