94 civic fuel lines
 

How big are the fuel lines that run underneath the car?
I need to know the size of all three.
Fuel supply
Fuel return from fuel rail
Fuel return from charcoal canister

i guess none of you have changed these lines before?
Fuel supply and return look line 1/4" lines but can anyone confirm this?
What fittings are used? 12mm?

There is no return from the charcol canister. It's just vapor and it's dumped I believe out of a tube on the passenger side that is just cut off.
If you're re-doing all those lines than it really doesn't matter what the stock size is. Just go bigger. >:D -6 will do it.

Goes to the passenger side rail and out on all my Hondas.I have turfed the canister on all of them as well.Should be 5/16 fuel lines or 8mm for the lines.

Check the lower passenger firewall and tell me what that cut off hose goes to.

we may be thinking of different pipes

I know which one you are talking about now but its not the same one.
The vapour pipe under the car is the one most toward the bottom on the pic. Anyways that one isnt important.

whats the fitting size on the fuel supply
doesnt seem fuel return has a fitting anyways

Re: 94 civic fuel lines
 

The fitting from tank to filter on the EK is m14x1.5 I know that much. :P If you're going all out on new fuel lines, I can't see why you'd waste your time on that tree hugging charcol cannister. :1
