Deleting charcoal canister

Ok so the po of my jeep has nothing hooked up to the charcoal canister. Well I have a lot of fuel tank pressure for that when I drive her a few miles I can take the gas cap off and the pressure is insane. I have 90 jeep yj with a 84 258 engine Holley carb and hei dist. Now the problem I'm having is every once in a while on the highway the jeep starts stumbling "example like I use my gas pedal like a bass drum " alot of jerking otherwise. So I can't find any vented gas caps that fits so I decided to drill a hole straight thru the cap well that was prior to me figuring how a vented gas cap works. So I still need a vented gas cap. Any advice . I live in fl no emissions here

The PO of my YJ took out the charcoal cannister, and I have put one back in. Without it, the gas fumes were horrible when parked in the garage. I would say, since the cannister is still there, hook it back up and your venting issue will go away.

But I no longer have my erg valve nor my Carter carb just one PVC to my carb and that's it... So hooking back up the charcoal is gonna be a little different plus the po removed the rollover and fuel vapor valve things that are tucked under right rear corner of jeep body

It was all removed from mine too. Just connect the out port to the PCV vac line, the fuel vent to one of the others, and plug the rest. You are no longer using it for emmissions, so it is simply a fuel vapor filter. The PO of my YJ solved the pressure problem by pulling the vent tubes off the top on the fuel tank... They were not too bright, this was one of many "farm engineering" fixes that I have corrected.

93 similar issue

I have 93 YJ 4.0 and have similar fuel tank pressure issues and the bucking you talked about. Don't know for sure what the issue is yet but when I dropped the fuel tank to replace fuel pump (after trying just about everything else to get the bucking to stop and replacing the gas cap hoping to reduce the pressure) I found a kink in the vent line. In about 8 weeks when i can get back to it after recovering from a run-in with my pocket knife I will put it all back together without the kink in the line and let you know if that fixes it. BTW, My charcoal canister appears to still be hooked up stock.

If you come up with something in the meantime please post it - I might have the same problem...

Knifed...

Yeah it is. My father-in-law is a knife maker and he sharpened it for me. It went through skin, meat, and tendon straight to the bone - and didn't hurt a bit - at least not until the doc got hold of it

Getting the original splint off tomorrow so I can at least start picking my nose again...

I have the same problem/issue. The PO has made a mess, the "carb bowl vent", "to fuel tank", "can purge", and "purge sig" are not connected or lines severed (see image). I see the "to fuel tank" line just hanging off. and I think the "purge sig" is severed, the others are gone.

I am going to D.U.I HEI the distributor soon, the Jerep is not "Nuttered" as far as I can tell. Could you please elaborate on "Just connect the out port to the PCV vac line, the fuel vent to one of the others, and plug the rest. You are no longer using it for emmissions, so it is simply a fuel vapor filter." Since you do not explain the actual identifiers on the the canister, I do not know what to plug in where. Ie. what is the "out port" what is the, "fuel vent" assuming "to fuel tank" to "others", Huh?

I too have no care for em missions, it is historically registered in Fascist Maryland. At least I get this one for free, LOL.

HEI next.
