Marshall, do you have pix on the way you solved the fuel line situation?......did you place a standard fuel line hose clamped to the hard line stubor did you plumb in new hard line on your fuel line to gas tank with threads write up?..last pix are not showing so maybe it is there TIA
Lou
Lou
Just used a stub and a hose clamp. Works great.

When I orded the nut a ferral I asked for one for a 76 fj40. Don't think there were any differences in the years though.
I filled my tank on the 55 yesterday after checking all lines...I missed this one. I have a modified and expanded tank and all the lines are attached. The only one that has nothing on it is the threaded one. It needs to be sealed off. It is no longer needed. It now has a piece off wood from the mulch at the gas station. The gas was flowingg out ot is in an amazingly fast flow. Mgiver came to mind and I decided the wood was the quick fix. I need to cap it and found this.
What part should I look for to get the threaded end. The 55 is a 71. I am looking for a cap or a fj40 part that I can modify to close this dam thing up. Kind of embarassing when the entire gas ststion is flooded with my gas leak!

The nut part # is
90402-13041
The Olive (lol ferrel) is
96395-71400
This covers 68-80 it is originally for the carb but it worked for me.

Lou,
Should I look further into venting rather then plugging the thing? The tank has 4 lines going to the emisions boxes on each side. I was assuming I can plug the last one uo. Guessing the threaded one left off was the old line to the engine. There is a new line in the top of the tank. Hope plugging the thing won't cause a problem.....
Goebs
And thanks again for Dan's info. I'll be making a list and calling him ......

need for venting the gas tank
Goebs; yes, need to keep the venting that goes to all 4 corners of the tank to compensate for different positions........believe in your case; a very early pig the thread was for some unknown reason a british pipe thread......later ones went to JIS metric standard........our gas caps are unvented so the mistake I found the PO had done was to plug off everything except 1 out flow to the carb and one input from the gas filler....one would think that not overfilling the tank and drive 40-50 miles would solve the problem.........
that was the mistake; as fuel is consumed it leaves air to fill the top of the tank and as the day warms up the air expands at a greater rate than the fuel and being on top as a gas it pushes the fuel out the path of least resistance; in my case the gas filler cap; in others cases it might push it out in other weaker areas.........guess what I am trying to convey is that the toyota mechanical engineers designing these vehicles had the training and the smarts to put together a superb vehicle within certain limitations of costs and when we attempt to modify things a lot of times we just set in place a chain of events that open other problems instead of solving anything
........luckely the gas pouring from my tank did not ignite
, but a chance spark a cigarret butt or? and poof.....I will be glad to just get my piggies back to original condition undoing the neglect and ill thought out mods of the last 30 or more years.......BUT.....must add that I have seen in this forum some absolutely awesome examples of beautifull restorations and upgrades that make me drool but being a former? hotrodder I know the amount of energy money and love that has gone into these vehicles to bring them to that point, in my case just happy to get them back to where they once were; just good solid transportation, slow but dependable and with the ability to go off road without wondering.........how the heck can I get back

There are venting tubes from the 4 corners. The passenger side has a larger tube running from the top of the emmisions control tank and down. I blew in it and gas once again came out the threaded opening like a garden hose. Back in went the stick. I think I need to learn more about the fifth line and where it is supposed to go. I think I need to plug the threaded still. I am going to drop the tank if I need to to see what the hell I am dealing with. Ironpig built the tank and had photos on their site. Maybe I can look for them again...
Goebs, am at a loss IPOR I know fabbed your tank and there were some pix on scottryans build thread will have to check..IIRC the 4 vent hoses coming out the DS rear went to the four corners of the tank as Toyota had them originally, there was a 5th larger one that went to the filler neck........I don't know if yours has the fuel/air separator; if so then another hose will go from the fuel/air separator to the charcoal canister in the engine bay.....then there will be a feed line from the tank to the fuel pump and then a fuel return to the gas tank........are we OK till there?....on the 74s till 79s that I have pesonally seen; 4 to the fuel/air separator on the DS+1 Gas 2inch filler hose + 1 from filler neck to tank...total of 6 on DS of tank + another from fuel/air separator to charcoal canister running alongside...total; 6 to DS of tank + another alongside it..........then on PS of truck......one hose to Fuel pump + one return from engine bay these 2 + the one from air/fuel separator run as partial hard lines on the inside of the PS frame separated by rubber deviders where they are hardlines....earlier pigs had a lot simpler plumbing and am trying to figure out what to remove/leave off or replace on the body transplant 79 w/o screwing up the basics as happened when the PO plugged up everything on the 78 except for the filler neck and the feed to the fuel pump taking out all venting....you can give me a call later this PM after I have time to find the pix of your tank build and see if we can figure out what is going on;

Fuel Line
As I was cleaning and putting a coat of paint on my 55 tank today I also realized that I have the screw on type. Since the brain surgeon that removed this tank cut the line I'm in the same quandry as what to replace or stub this with. Are you guys saying you are creating a sub with an aisin carb inlet?
Thanks

You can just get some fuel hardline from most auto parts store. Only need about three or four inches. Then use the nut a ferral listed above. Then you can just slip a piece of tubing over it and clamp it down with a couple hose clamps.
That original piece of hose is not available anymore so this was the only fix I came up with. Works but I'm sure there is a better option.
Question of the day...
Does anyone know of a vented gas cap that will work on the original fuel filler tube on a 71 55?
Thinking I might want to do this just in case my fuel line plugging isn't the best fix for my tank.

Goebs; I looked for a vented gas cap but came up with zero; one way of venting would be drill a small hole in the middle of the gas cap as suggested in other threads............found it easier to go back to original as much as possible........do you have a air fuel separator on yours?; it is located in the drivers side rear quarter panel area and the 4 smaller hoses feed to it; the 5th medium size hose feeds to the filler neck; if this is the stub that is capped with a piece of wood you might see if the stub it goes to on the filler neck is still there then route a hose back again between the 2 stubs....hth;

Lou,
I have one on the drivers side and one on the pasengers side. The one on the passenger side has one tube going to the tank and one not going any where. I was thinking it shound be connected to that threaded line via some type of hoses. The other side has two lines that go to each side of the black fuel thingy and back to the tank. The darn tank is custom so it is difficult figuring this one out. I might have to try IPOR again to see if they can jog their memory. I am going back out soon or in the am to see if it makes more sense.

On my '76 there is a fuel supply and return on the passenger side, 4 vents on the drivers side as well as the big fill hose and a 1/2" or 3/4" overflow that I believe ties into the filler neck.
