What is the part that I have circled in red? I know the blue circle is the heater fan. The reason I ask was when I first got the car and it had a 250 in it, that part was never hooked up to anything.
That's because it was one of those useless parts the factory somehow thought was needed. Just running the tank vent into the air cleaner accomplished the same thing.
I'm going to be running a fuel cell in the back. I was planning on using the top vent of the cell for that anyway. Thanks, now I know I can just remove it to clear up some engine bay room.
That was the first ting I removed and plugged the lines in a Duster I had years ago but didn't know at the time it contained the tank vent - every time I opened the gas cap, I got a pressure release
Actually those help keep your front end in line. I took them off of a Mustang I had and after that the front end would not keep a front end alignment. The guy at the shop told me to put them back on and he would realign the front end, and it stayed aligned!
The reason for the canister is to store the fuel vapors. Once the engine is running, the vapors are pulled from the canister and burned. If you just run the vent line into the air filter, the vapors collect in the filter and make a warmed up engine hard to start. It (in effect) floods the engine. I found this out the hard way! I hooked it back up properly and no more issues. It probably wouldn't affect a car in a cold climate, but it sure doesn't work here in Fl.
could you explain how the canister "stores" the vapor. is there a valve in the system that opens after the car warms up? if not...with the flap closed in the breather snorkel, on start up the vapors are drawn from the canister as soon as the engine turns over the first revolution and should cause that same "flooding" effect....
I just put a nascar cell in the trunk of mine. I routed the vent hose down into the well behind the right rear wheel, there's a hole in the inside wall of the well there that's perfectly sized for the 3/8 vent hose I used to poke thru. I had a tank in the bed of my 89 Ranger with the V8, I routed that vent hose to the aircleaner, ran it like that for years, worked fine just like that.
No, it does not. I ran that setup on my V8 Ranger for years. Never had flooding problems. It's just as hot here in the summer as Florida is. If anything I think it made it easier to start. As for the volume of vapors, that too depends on where the tank is located or the car is parked (in the sun) and the fuel in the tank (high RVP, low RVP)
