Getting ready to put the fuel tank back in... vapor canister line

[jjlaughner]

Do I need this? I thought about removing the can to make way for some mods. If not I need to find a rubber line to run with the fuel lines. Theres a rubber line on the canister but it disappears under the motor somewhere and there are no rubber lines past the tranny /forums/images/graemlins/thinking.gif


Am I correct in assuming the vapor line goes to the canister? /forums/images/graemlins/confused.gif

Yes it is worth hooking up. It sends the extra fuel vapors thru a charcol filter rather than straight to the atmosphere. It is an effective pollution control with little to no maintenence required and also doesnt hurt the performance of your truck /forums/images/graemlins/thumb.gif

Not only that, but if you don't vent the tank with another cap (which apparently can/will eat your paint around the fill neck after years) it will build up excessive pressure inside which can cause more problems.

Also, the EVAP system should be fairly effective at keeping condensation from getting into your tank (an early low pressure vented gas cap may work too) which will rust it inside out.

/forums/images/graemlins/thinking.gif maybe I will relocate it to another place then. Its going to be in the way. Now I have to go by 20ft of rubber line /forums/images/graemlins/rolleyes.gif

If your really bent on getting rid of the charcol canistor, put a check valve on the end of that line, so it continues to vent...simliar to an axle vent line check valve....my buddies '77 1 ton had one from the factory
