Trying to get a reading from the stock gauge is like trying to get temperature from a clock. Thing is about useless as far as I'm concerned. At start up it's reading as operating temperature. at operating temperature, it's reading operating temperature. Aired down to 9PSI going 65 down the highway it's still dead center even though my DSM gauge is reading 200+.
Keep it TOYOTA!

In the past years, I used to get a lot of calls from Jeep owners wanting to go slow like the Toy trucks.

Gotcha. Well I ordered an ob2 Bluetooth module. It says I can get a temp reading from it. Not sure if it will work with this but hopefully.
This way I'll have all digital tach, temp etc. I

It will capture all generic ob2 data, which includes temperature

So the tube that goes off the charcoal canister is leaking gas now?? What could this be?? My canister makes a weird buzz ever once in a while, I unplugged all the electrical and it still does it. What the heck could this be?

Okay so I've read up a good bit. I tried to open the gas cap and definitely had good pressure. But the dripping didn't stop. I guess the buzzing is normal. However has should not leak from the air  drain hose.

Do I need to replace the canister?

Okay so I pulled the return line from the canister and then replaced it. It seemed to have some back pressure when I first pulled it off. He pressure came from the tank. After I pulled this line the dripping has stopped.

Do I have a faulty canister? Seems so odd to me. I'll have to keep checking on it. But this is the first time it happened. Maybe has something to do with the gas tank being full as I normal just throw in whatever cash I have at the time and never really fill it up.

Do i need a new canister?

IS it possible i have the return and evap lines switched? How would i know if i did?

When I did my swap, I labeled hoses, then followed back to tank. You could try swapping them  :dunno:

Yes just tried that, but now the sun is hiding and it always slows down when the sun isnt out. Its still dripping slowly, not sure if that was still just left in the rubber line or not.

What would happen if they were switched? I didn't seem to notice any issues until I filled up my tank. Maybe I overfilled? But I just waited for the pump to click and didn't keep going.

Tomorrow, I'll chase lines down. Are you using the 87 fuel tank

Yes sir. All p/u stuff is from an 87 22re setup.

My 4runner is 87. I'm sure they are the same. As far as fuel/return/vent on tank

You should not have raw fuel in the canister. You either have a plumbing issue or bad canister.  Typically fuel in canister is caused by overfilling tank.

a

I suppose it possible that it was overfilled, I pumped normally and let it click off, (not topping off) I think i may have had return lines mixed up, but not really sure since it runs all the same either way. It will only leak when It is over 70 degrees / sun is out and truck is off.

It sounds like you have your vent and return lines mixed up. The return line drops down to the bottom of the tank so if they were mixed up you would be venting liquid gas. The system is designed to vent fumes out the drain tube when the engine is off and there is excessive pressure in the tank, otherwise it's venting fumes into the intake when the engine is running. It's not very easy to flood an evap canister that is under the hood compared to newer vehicles that have them mounted near the gas tank when (over)filling. If you want to compare your connections, I'm in the San Diego area.

One question for you swapped 3rz out there. What is your running temperature? I'm sitting just slightly above half way mark on my 87 guage.

my gauge also sits slightly above half way(185). one of the beauties of the swap is the obd port which allows for monitoring and diagnostics. I use the torque pro app along with gaia/avenza gps for offline mapping

My truck sits about 210(using OB2 scanner), is that to warm? Im pretty sure I bought a 180 degree t Stats... Anyhow i have no fan shroud so that could be part of it.

If you want to compare your connections, I'm in the San Diego area.

I've switched the lines and ran the truck for a good while just to try to use up some gas. I'm thinking I had the lines mixed up and I had my tank overfilled, guess I'll just have to be careful at the gas station when filling. Not a drop has come out of the vent line since and we had a few warm days, which is when it typically happens.

Also Id love to come check out your rig sometime, just to see what you have done to it. Not that I could really drive my rig anywhere yet, still waiting on my PS box to arrive.

I did get a few things done today!  :beer:

Got my spare tire mounted on my extra rim finally...

I also got my pitman arm all figured out! I picked up one from a 3rd Generation Toyota P/U 2WD with power steering. Its perfect option that's in between a flat arm and the 3/4" less the stock drop Sky arm. Part#45411-35320 You will have to file 2 splines into it. Super easy using a triangle file.

I ordered it from https://partsouq.com. I was a little skeptical at first since it was half the price of others, but It arrived pretty quick.

My truck runs all day at 187 degrees F.
So I am running too hot? Should I replace the Tstat? Any other recommendations? I have a new radiator, just flushed and new coolant.
Maybe I need to try to make a fan shroud that would fit.

Are you running 3rz fan..  I'm using 22re fan and fan clutch, with stock 22re fan shroud.

Yes I have the 3rz fan, I thought It would cool better since its WAY bigger.

How's your fan clutch? Also I'm running aluminum radiator. With as shroud. I was going to go 3rz fan route. But when I saw it wouldn't fit into shroud, I decided on 22re fan,fan clutch, and shroud

Im using the RZ clutch, Seems pretty good, yes same here 3 core all aluminum as well. I might just try to make one see if it will make a difference. Or maybe add a pusher fan on the front.

Didn't notice a difference on the temp gauge with or without a shroud.

What gauge are you reading off. The stock gauge in cluster. Or aftermarket.

I have an ob2 unit that's giving me live temperature. The gauge itself only reads half. But yes useless for actually temp.

I only have an electric fan on a thermostat switch and mine never breaks 187-188. I suggest to put your 22r shroud and fan back on or go electric.
