April 7, 200420 yr comment_75821 I've seen other posts about removing the evap. tank. Just out of curiousity, why would you want to remove it? Link to comment https://www.classiczcars.com/forums/topic/11135-evap-tank-elimination/#findComment-75821 Share on other sites More sharing options...
April 7, 200420 yr comment_75831 For infoUK 240z's had no evap tank from new. Just one tank vent pipe that vents into the filler neck, and a drain pipe from the filler neck to air. UK fuel tanks only have one vent pipe.This is what I am following for my 1970 ex US car as the plastic evap tank is brittle and cracked after 35 years. I have also removed the pipework from evap tank to engine block. for what its worthAndrew Link to comment https://www.classiczcars.com/forums/topic/11135-evap-tank-elimination/#findComment-75831 Share on other sites More sharing options...
April 7, 200420 yr comment_75838 I had asked becuse I have a 78 which has a metal evaporation tank. It has never caused me any problems. Is there some advantage to removing them or is it just to eliminate a damaged one?

April 7, 200420 yr comment_75845 Would removal of the vent tank be a problem for a US smog check? It does cut down emissions by recirculating petrol fumes into the crank case.I suppose a major benefit would have not having to replace as many of the extremely expensive fuel tank hoses.

April 7, 200420 yr comment_75856 The fumes don't go into the crackcase. That would be dangerous. Instead the fumes, and any overflow from expansion, are collected and hopefully condensed in the evap. tank and returned to the fuel tank. I dunno why one would want to remove the evap. tank either, except to simplify things. The filler neck should be able to hold some overflow, if the tank is not too full, and recirculate some condensed fumes. I think I would rather eliminate the carbon cannister. cheers! ciao! gesundheit!

April 12, 200420 yr Author comment_76754 When the evap tank is removed .The air that is in the fuel tank when the car is refuled is vented into the filler neck and out of the car. This is the difference . In most of the states there is a rubber seal on the dispenser nozzle that will capture these fumes. The vent line that runs from the three way valve , this should be connected to the fuel tank to replace the air volume in the tank as gas is being used. Eliminating all the vent lines and the evap tank helps greatly to eliminate the smell of stale gas in the cabin of the car. In fact it should stop it altogether.:classic: Link to comment https://www.classiczcars.com/forums/topic/11135-evap-tank-elimination/#findComment-76754 Share on other sites More sharing options...

April 12, 200420 yr comment_76773 You could just takethe evap. tank out, but thewn you would have to be carefulhow full you fill the tank, especially in the summer, or the gas will expand & overflow- which is what the tank is for.Bill--You should try this web site: http://wordweb.info/ Link to comment https://www.classiczcars.com/forums/topic/11135-evap-tank-elimination/#findComment-76773 Share on other sites More sharing options...
June 12, 200420 yr Author comment_84847 I roll up the windows when it is raining and when I park the car outside. The three way valve will take care of the expansion as it has all along . If you like the stink of stale fuel that is up to you. go for it. Driving around with the windows open is like sticking your head in the sand and disappearing. :stupid: :stupid: Link to comment https://www.classiczcars.com/forums/topic/11135-evap-tank-elimination/#findComment-84847 Share on other sites More sharing options...
