My gas tank has been pressuring up & ignored it to the point that my fuel tank ended up acquiring a stress crack. So a fuel tank replacement is coming up soon, but for now I installed the replacement charcoal canister. Toyota no longer sells the stock one... so the AC Delco 215-153 & a AutoZone VC120 are as a direct fit one can get.
Here's the AC Delco setup. It comes capped from the factory, but I removed the cap from the air line and left it open to replicate the bottom hose of the original set up.
As others have said, I deleted the bottom bracket and used an extended bolt for the top. The bolt I used was an M6-1X50. It's just long enough to work. I also just left the air line open, as I don't see too much purpose in routing it down to the frame, but if someone convinces me otherwise, I'll add a hose there.
Last June 2017 I went ahead & purchased the Intermediate Slinky rear coils. When I originally purchased the rear slinky coils they just had 160/320# heavy coils in stock, I didn't want to wait another 2 months for the lighter duty coils. The heavy coils were just that... I run a light rig so the normal 160/270# Intermediate coils suite my needs much better. If I had a dual swing out & spare tire out back the heavy coils would of been just fine. As far as specs... turns & free height are basically the same but the wire diameter looks to be a couple mm thinner.
The ride is much more supple but the handling is really good. I only run approximately 250 lbs overstock in the rear so I can feel that I'm still in the 160# rate then when my family climbs in I can feel it hit the 270# rate. The on pavement ride is like a stock feel same as the heavy coils. The real difference is on the trail... they compress more & soak up some of the heavier hits. Also when I wheel solo... at the end of the day my back likes me better.
