75 power wagon fuel question

[gilberttitan08]

I got a 75 dodge power wagon and there is this fuel line that comes off the fuel tank and used to go into a charcoal (vapor) canister that bolted into the radiator support. I have removed the canister since it broke into pieces. Now my question is, how should come about this, should i cap off the line?

I don't know. If possible, find someone online or otherwise, with a factory service manual. "We" have discussed this no end here. In the car line, that line to the rear IS the vent and generally speaking, you want to leave it OPEN "up high" somewhere for a vent. You can also plumb it into the open part of the breather AKA the air filter bonnet.

The fuel cap, I'm sure, is what is known as "pressure / vacuum" which is a way of saying it relieves pressure either coming in or going out. this is not the same as vented
