Smelling some unused gas towards the rear of the car after some spirited driving.

I was doing some spirited driving today manual shifting around some backroads. I pushed granpa car harder than I normally do, doing some nice counter steers (drifting a bit) etc. Well after I pulled up to my house I smelled gas towards the rear of the car sorta where those black fuel whatever lines are in that mount inside the rear bumper. Is that normal? I would say either it was unused or recycled gas is my guess? Pretty much my question is what do those black plastic lines in the bumper do? I also have 103 autoites gapped at about .40 currently so that could be a reason im running a bit rich, but the plugs show a pretty clean burn... maybe a little uneven on the electrodes because of the close gap, but nothing too substantial. I'm not running the juice most of the time so im debating whether or not to put different plugs in?

running lms chip - 160 T stat fans coming on at 175, it runs pretty cold normally never leaving the L on normal even if im romping on it, itll just barely go above between the A and the L in street driving. So I assumed that the one step colder would benefit NA driving, but with this gas smell and sometimes the cats smelling like rotton eggs ehh im getting a feeling something is off. I'm not getting any CEL's and it doesnt stumble at all. As others run two step colders, i know geno runs stocks @ .048 gap right?
I ran the 103's gapped at stock at about .054 and with the chip in their the car acted funky longer revs and stumbling, with out the chip is was fine.

let me know what you think, trying to tune this beast... I spray pretty regulary but as I don't know if its enough to warrant keeping those plugs in? Or if those plugs are perfectly fine? IDK! I'm not sure how to go about tuning this thing relating to colder plugs vs fouling vs spark plug gap.

ive also been tightening my plugs hand tight, a buddy of mine whos a tech said i should snug em up with the ratchet but I read a bunch of horror stories about messing up the threads in the heads so i always just do em as much as i can by hand? maybe not enough torque on the plugs possibly as well?

They need to be tighter than "hand tight" but not a great deal more.

If you dont get them tight they will blow out..and take the threads out of the head when they do.. {been there, done that)

The torque spec is insanely low, but it's probably a little tighter than "hand tight" unless your King Kong with Kung Fu grip.
 
The gasket is fine... As for the plugs, I snugged em all up. Normal driving I don't ever notice it so it made me think I was running a bit rich. What do those plastic lines inside the rear bumper do? There just black plastic and have some kind of rubber thing on the end.
 
Do people not own torque wrenches?

Everybody's "snug" is a lot different, but every calibrated torque wrench's 15 ftbls is the same...
 
Mine does that below 1/2 tank, did it with the fuel cell and the stock tank.

so does it have something to do with the evap system? I was driving normal around end didn't notice anything as for the plugs I guess I gotta buy a torque wrench just to make sure my plugs are in right :-(
 
Abe with half a tank and spirited driving you are creating a lot of sloshing in the tank which creates vapor pressure. The pressure has to go somewhere most likely over driving the evap system.
 

someone has a great sense of humor!


Do you have an annoying rattling in your mufflers? Are they sagging a little? Don't quite sound right? That could be the symptoms of a worn muffler bearing. Allow me to introduce the KaleCoAuto muffler bearing! It's unique iron-graphite composite with pre-grease-packed assembly provides over 200,000 miles of smooth muffler operation! It is most likely they will outlast your mufflers. Also works well on heavy duty exhaust systems. One per muffler.
