Off Topic but did anyone see that Buick is bringing back the Grand National, T Type and GNX? Not looking like they'll be the fastest production cars like in 86/87 but still awesome nonetheless. They're a way out yet (maybe 2014) and I'm curious to see what powerplants, thinking 3.6 turbo for the GN/T Type and the new LT1 for the GNX. Guess I'd rather have the CTS V for a daily driver! Just had to mention.

 

I like the caddy myself. I have a buddy with an 87. It runs like crap. It is a wiring nightmare. In its day it was just about the fastest car I ever rode in. Now I laugh when he tries to scare me.

 

I wasn't suggesting that at all. Only that a tank under pressure will help to keep the pump primed for an easier restart is what I was getting at.
Oh, and those dorks with a stuffed rag, I call those a Molotov Cocktail on wheels!

 

The vent also lets air in as you use fuel up. If you didn't have some sort of vent, whether through the cap or the charcoal canister you'd build up a vacuum in the tank and you wouldn't be able to draw fuel when the vacuum was great enough.

 

I appreciate all the insight about this vent line gentlemen. Not sure if I understand the venting of air in as opposed to out but as long as venting can be done in the back of the car and not the engine compt. I'm cool with that. It would be a good problem to have if I was out in the garage tackling this right now but as of today, it's officially too cold to be out there working! Next step is to get a new source of heat out there. The wood stove takes way too long to warm up and with it in the 20's, I can't do it by just bundling up. Think I'll get one of those LP forced air torpedo type heaters and be ready to work in minutes as opposed to hours. There goes my poly bushing money.... lol

 

I'll add this. Over the summer when working on my truck. I put my 16g fuel cell in the back because the PO decided to weld the tank straps in, which are really 1/4" plate. Fine on a new tank, crappy for a guy wanting to pull it. So anyhow, I hooked it up and forgot to take the cap off the vent. In the sun the tank swelled up. Then after getting it running it ran for a few minutes and the vacuum created by the pump collapsed the cell and the motor died. Hmm, I removed the vent cap and the cell popped back out. And then i primed the carb and it fired right up. So my though it has to vent in as well as out. In through the cap or return, out through the canister. The canister scrubs the raw fuel smell.

 

I wonder if the cap on there now is vented then? It's old, and metal, kinda like my back. Is your pump mechanical or electric? The return line was blocked and the tank never looked like memory foam that I'm aware of so hopefully I'm good. Strange thing though, I can stick my nose right over the end of the line in the engine compt. and not smell gas? Interesting stuff though, glad I asked, never would've thought there was that much to it. Sincerest thanks and appreciation everyone.

I guess today's the day I change out the summer wheels/tires for the winter ones. Gotta love when the weather channel says "accumulations of less than half an inch" and you get 6" of snow overnight!!! Promised my kids I would come and have lunch with them at school today so I better get busy.

 

Not unless somebody changed something. Your car has what's considered a sealed system. The reason for the setup your car had was for emissions to stop the outward whoosh of gas fumes that older cars can do when removing the gas cap. Think of your charcoal canister as a holding tank for fumes from the gas tank. Then when you start the engine, the fumes are sucked into a manifold port of the carb or intake manifold and burned. My car has no additional venting, except for the gas cap that lets air in, not out. So yes, my tank will pressurize, which is normal, but the cap will let air in to compensate for the fuel getting drawn out. That is how a vented cap is designed to work, and if you have one, it will be stamped "vented" on the face of it.

 

I purchased one off the local CL for $40 that was like new! Might check the local listings for a good used one. I see them here for $40-$60 often. I love mine as it heats the place up in minutes, and then I shut it off until it gets too cold.

 

I've been looking around and found a kerosene torpedo heater for $65 but would have to drive almost 2 hours to get it. There goes the savings. I read some reviews today on Home Depots site and looks like I can get one of the smaller heaters for $100 and that should work perfect for me! Glad I read them as everyone says that the smaller heater is just about as good as the bigger ($200) one. I'll pick one up this weekend.
