Hi all,
I am going to remove the EEC (Evaporative Emission Control) in other words the Fuel tank vapor canistor. I dont want to have the fuel tank vapors venting in the engine compartment. Does anybody have any ideas on how I prvent this?? If I cap the vent line from the fuel tank, will this cause vapor lock? How about putting a tee connector on the PVC hose and have hose from there to the canistor vacuum purge valve. Any ideas comments, suggestions, or what you have done will be greatly appreciated.
i have a question about this. ive converted my engine from TPI to carb and i removed the canister. stupidly i tryed pluging up the hose and my car stopped running after a while (would start running again after a half hour or so). so i opend it up and WOW, it started running again i just routed a hose from the line down through a square hole where the canister used to be so really it vents somewhere between the wheel well and the nose on the passanger side. is this alright to do? its been running quite nicely for the last 5 months and ive had no problems. honestly i cant see a way to hook up the canister so that it returns the vapours to my carb. all of my vacuume ports are being used. but like bluegoose mentioned, could i just connect it to the "pcv hose" that goes to the front of the carb? or would that create to much of a vacume for the canister to handle, causeing it to suck in un-purged gasses? would it really be so bad if i just hooked the vent line to my air cleaner some how? i mean its still flamable gas right? what are the benifits/disadvantages of it being hooked/unhooked?
I've removed my canister entirely. I know of several others who have also. The two basic methods are to either cap the line OR to run some fuel hose from the line to a small fuel filter that is placed in any hole you can find up there. This will vent the tank vapors away from any danger (sparks, hot spots, etc.). I've taken the little fuel filter venting route. Others that I personally know have taken the capped approach and have been running like that for years.
