evap delete question? Ok i have my evap deleted and all the lines around intake are gone. I ran a line from the factory line under the car so i wouldn't have to smell gas as much. Well now im wanting to drop the tank and remove the charcoal canister for extra weight loss. If i do that everyone says it will smell like gas in the car bad.
Well the question is can i just cap everything off and run a vented gas cap so all the smell is out of the car and at the rear of the car?

after my twin in tank setup, i ended up with only one vent tube (factory vent). My tank didn't have enough vent to it and i couldn't find a vented gas cap for the 98 tank, so i put a better one way check valve on the end of the vent line and did away with the factory crappy plastic one way valve. I ended up getting a air ride one way valve from orielly's that had a 3/8"s pipe fitting on it and it worked great, I will be reusing this setup on my new car.

removed my EVAP, still using the factory vent. id suggest using some sort of vent other than only a vented gas cap. without any other vents, u may have a hard time putting fuel into the tank
where is the factory check valve? i wanna modify that to make inserting gas easier

I've deleted all my engine EVAP hardware and lines for a nice steel braided fuel line setup, all I did was delete the codes and cap off the vent hard line with a small hole cut in the cap that I used......never had a problem with smelling gas or filling up ever.

Great pics 
Anyone use a 3/8-3/8 fuel filter for a vent, just to keep trash out over a open line. Some have a removeable filter to clean. Maybe but some charcoal filter in there, to keeo the smell down.
Or some drier sheets in a tube

No I put it all back in, and everything 100% stock. I had troble getting it to purge and get the readness motior to complete (to get the car inspected). I filled the tank, parked at car in the cool garage over night, left it in the hot parking lot. Only messed with it for a few days, but ended up having all the other montiors check, but 1 other one that I didnt think would? But got it inspected with the 2 not ready and havn't checked them for the rest of last year.I may remove it for the weight, and with the SV Id have to add another fitting for it.

ya, I;m gona take the whole metal line off for weight so there no going back, but I could put the carcoal canister back in and have it vent thu that, and shouldn't smell. But worried like you, and running a muffalr in the back it gona be heating the fuel up and have alot more venting then a car with open header.
Looked at it more today with the tank out. that white valve thing, the line off it on my car dosn't do ****. It dosen't flow air in or out???? even putting a few pounds into it, or filling the tasnk up with a few to ballon it, it is sealed up tight, I think thats the "fill limit valve: and it has someing inside thats a floating check valve for when the gas it full in the tank or somthing. But its not going to work as a open vent. It just runs to the back of the tank and points to the ground so, just gona leave it like that.
Only line thats dose is the lines off the mid black fitting with the T. Theone is smaller line is 5/16 nylon thast gose to the middle line in the pump sender unit. I think thats the "fuel tank presser" that has a noild to contraol it. That fitting dosn't pass air, must be ele. controled.
The big fitting is 1/2 or 5/8th that gose to the charcol canister, and the evap system. its gona be harder to find a breater for that size line.
Not sure if I can remove the fuel tank pressuer line, just cap the port on the upmp sender (middle port) and use the smaller line on the T for the vent, and cap the bigger one. I think that 3/8 line with a fuel filter on the end flows enoght air to fill that tank fast like normal at the pump. Then I can remove all the wireing for that "fuel tank pressuer" solinoid. But not sure if that is used for normal tunning? like uses for the fuel trims???
I have a spare harness I'm remove extra and un needed wires form so can get at system all gone if I dont need it.
