I've had other requests for the design. When I built my new desktop computer I did not realize that I had not saved the files to my network server. The files were lost. When I called Oval Craft, I found out that the company had been purchased by another company and they purged all the files that were not standard products. The photos should give you enough information to have a shop build one. You will need to give them all the photos and your Vapor Recovery Tank Cover.
is this canister still available?

Nice work! Most people don't think it's important to keep the evaporative emissions system, especially when they de-smog.
Anyway,for a good-looking fix for an out-of production part.
Until they end up with a vehicle they can no longer drive because it reeks of raw fuel inside!
Then all that "emissions crap" suddenly becomes interesting again...

I have a Fed-spec '78 w/ a 9/77 build date. I thought my vapor recovery unit had 4 lines into it vs. your 3?
I'll have to take a look...
Thanks for posting this! Good stuff!

I am probably confusing with the Pig which has 4 vapor lines, I believe one from each corner of the tank
I dig it! Better than the original plastic stuff, and fits like factory! You'd never know it was there without disassembling stuff. Do you have anything indicating the construction of the thing? It looks simple enough to just make from scratch.

The tank is made from 3" Aluminum tube. You would have to take my pictures and your factory cover to determine placement, clearance and sizes for the components. All the bungs are 1/8" pipe with adapters to barb. There are 5 ports at the bottom which will cover various FJ models.

Has anyone opened up one of the recovery units? I'm curious as to how the ports are connected internally. It seems like you could almost tell from the outside given the bulges, but that may not be what's actually inside.
Also, since I replaced my '77 tank some time ago(I hooked up all the lines to the recovery unit like it was originally), the tank is still pressurized when I stop to fill up. Is this normal?

Are you sure it's positive pressure, and not vacuum? If you have a check valve and a vacuum draw it would have negative pressure, which would be correct.
i built my own recovery tank out of 2 inch plastic pipe. the lines from my 28 gallon tank all to the bottom of my 5 inch long pipe with caps on both ends. the input is from the tank and the top is an output from the tube to the charcoal canister. I don't have a canister so I piped it into the air breather.
works fine and no gas smell in the cab. no pressure on the tank either. Note that some model have to have a vented cap that is how they were disgned, but of course that fails emission check. so buy a vented cap and keep your non vented and when you go to pass emissions put on the non vented cap.
you can pick up a vented cap from Napa part # 703-1034

Yes, positive pressure- blows out when the cap is removed. The tank vent lines(3) are connected to the vapor collector, then out the top to the charcoal canister in the engine compt. through the little check valve(it is open--both ways). The second top port is plugged. The bottom canister port is routed to the frame interior--no evidence of fuel here-vapors or liquid. Before I installed the tubing, the canister was free - you could blow through either top port and get air out the bottom. Maybe the vapor collector is plugged??

Do you have a picture of this set up?
home made gaz vapor seperator
here is a picture of my setup. I no longer get the pressure build up and since I routed the output into the breather I don't smell fuel as it gets sucked into the engine. it does however still smell when it sits in the garage and it is hot. so I crimp the hose so it is in a closed loop.
See attached picture. I mounted it above the tank on the roll cage.

Think that will pass a visual smog test?
I have never had them check inside my rig, they usually look for the charcoal canister and move on, you can feed this to the canister if you have one, mine was toast and since I have a v8 deciced to bypass it all together. my rid of considered a play vehicle so I don't have to do emissions any longer.
I am clearly way late to this thread - but - I have been looking for one of those fuel sperator protective covers for months with absolutley not luck. Can somone point me in the right direction? What is its proper name? Got to have one!!!
