I already replaced my OEM tank. I really didn’t want to drop a grand on an extended fuel tank. I had thought a 7-8 gal tank behind the seats and roll cage cradle that could tap into the OEM would be a neat option for long trips, but it would...
1978 FJ40 Gas Tank in very good condition. Very little visible rust (some rust on exterior surface but nothing that appears excessive or compromising of tank integrity). Interior surface that can be seen looks clean with no signs of rust or...
i found a leak in my tank so I think it’s probably time to replace it. I’m looking into options. CCOT seems to have a decent reproduction tank at a decent price ($571), but not currently available. BTB has one ($652! on back order. SOR is...
If you can find a replacement separator, you can probably use some JB weld around the metal tube. It's not the first choice, but when one of my nipples broke off, I superglued it just to hold it in place and then built up JB Weld around it with...
I may have found the source of the smell (hopefully). After taking into account all the great feedback and comments, I checked the Evap Separator and tubing and discovered that one of the nipples had been broken off a LONG time ago and the whole...
I’ve been looking for material. Toyota sells it for $46+ but I can’t understand the length and if it’s enough to do all three or four connections at that price. Guess I can hit the auto stores buts its never a sure thing anymore.
If you replace the fuel or vapor hoses, be sure to use materials rated for gasoline. Even brand new lines not rated for fuel can pass vapors through the rubber. I know first hand !
I also had fuel smell issues the last couple of years. Before ripping out your fuel tank try replacing these 4 hoses that go to the evap unit from the tank with new fuel line. (Apologies for stealing this picture) My lines were original and...
Just behind the cover, passenger side just left of the door opening (silver in pic #1).
You should see something that looks like pic #2. Sometimes these connections can loosen or the lines go bad.
FYI - be careful with the plastic separator/manifold, it can be brittle after many years of service. The below pic was the culprit of my gas fume smell inside my rig.

That evap lets pressure from tank vent & separate funes go to charcoal canister & fluid goes back to tank. The inspection of drain hole is NOT for a leak at drain plug, usually the edges of the hole will be wet just a bit and it can be fuel from...
I drained and replaced the plug awhile back (before this all started). I put a new gas gasket on. I’ll check that closely.
What exactly is the “evap”? There is a plastic manifold behind the filler tube. Is that you mean by the evap? I...
The first thing I would check is the rubber fuel lines that connect the hard fuel lines right above the frame. They get old and cracked after 45 years.
have a look at the drain hole under tank, wipe finger around hole & smell, check fill/vent hose for cracks, verify lines from evap to charcoal can are clear, if all those are good and you have wetness around drain hole it is probably pin holes
