Replacements for Liquid Check Valve/Roll Over valve

I have been all over looking for a liquid check valve and a rollover valve. Been to all the major autoparts store's and they just look at me like I'm crazy. I found some online at Georges, but had two questions before moving on.

A few Quick questions
1. Has anybody found an alternate replacement for these?

2. For the Liquid Check Valve, I understand it's purpose is to keep fuel in the line between the tank and fuel pump. Is this correct? If not, what does it do?

3. While I am trying to get the jeep running, is the roll over valve really needed? or can I just plug the end of the line without affecting anything.
The jeep is currently on a set of jack stands and not coming down anytime soon.

I have always thought that the "Liquid check valve" served as a vent(via charcoal cannister) until the unfortunate event of a roll-over, then it would shut off, preventing fuel from spewing all over the place.

The liquid check valve allows vapors to pass through to the canister, but prevents liquid fuel from passing. It works when the Jeep is right-side-up. The rollover check valve shuts off fuel flow if the Jeep becomes upside-down.

I posted info on replacement rollover check valves just the other day in this thread: http://www.jeepforum.com/forum/f8/roll-over-check-valve-175390/

Nice find indeed! Been looking for a replacement one for awhile as my OEM one has a rusted hose barb on it and can't be used unless a braze on a new hose barb.

Sweet find! Those work well on the other vent lines also.. tranny, transfer case, axles...etc. Keeps the oil from running out when your on your lid.

Like I said, great find indeed and I received mine today and they fit and function just like the originals from Jeep. They have the same bolt pattern to to mount on the wheel house support bracket right where the original Rollover Valve was...no drilling another hole to mount it is needed.

I bought 2 @ $5.95 ea. and with shipping the total came to $19.82 to my door. These Rollover Valves are quite rare to find if you find any at all that are OEM compatible. I think Collins Bros. Jeep used to sell them for like $40 or $50 dollars each. Some internet sites sell other type at 4 times the price!

Get them while there hot boys! They are not going to last once the Jeep CJ world finds out about them.

Here's some pics of it along side of the OEM one that is rusted and missing a barbed tube and also of it mounted in the original position.

Yeah, I saw that and that is why if anyone needs one now or in the future, you better get them as they are NOS parts (new old stock).

Not going to be in stock for long.

I'm confused. I just looked up under my '84 and don't have any valves that look like that. I just looked in my Chiltons and it shows that setup for 79-81 and in-tank valves for 82-86. But Keith's '84 obviously has them. Or does this depend on if you have 15 or 21 gallon tank?

Yes, they are for the 15 gallon tank like most of us have.

Well if they run out, check out your local Nissan dealer - the black rollover check valve in the lower left of this photo is from a mid-90's Nissan Altima. Only real difference is the way it mounts, which is why the zip tie.
