Remove them. I guarantee you already have rust, and it's only gonna get worse.

Ethanol in the US is a joke for a couple of reasons. Actually it's nearly criminal. Ethanol has a lower energy density than gasoline, so it's no surprise that most vehicles have worse fuel economy running on E10 blends. Certain engines, have actually been known to have economy worsened to the point that the overall rate that gasoline is burnt has actually increased! Go figure huh. The great "environmental" irony is that ethanol burns cleaner than gasoline - this is true - however in the US (and Canada, by extension) ethanol is derived from corn. As you've probably noticed after eating corn on the cob, corn is incredibly tough. To process the sugars into ethanol and break down the fibrous matter, the corn is made into a slurry and cooked in coal-fueled furnaces. So not only are engines using more gasoline, but we're also firing massive coal plants! Yeah that sounds green to me! In addition to this, the whole nightmare is actually driving up world food prices because we're using food for fuel... and world fuel prices because we're using more fuel because the food doesn't burn well enough! (Technically the corn used in ethanol isn't "food grade", but tell that to cows. As well the amount of arable land is very limited and this is a colossal waste of natural resources, and stuff like fertilizer) Literally the only parties that benefits from ethanol are corn farmers, who receive a nice government subsidy to waste gas instead of feeding people.
Brazil, on the other hand, is doing it right and using sugar cane, which is easier to process and much more efficient in terms of resource use to produce a certain amount of sugar (way sweeter than corn...). The US and Canada would be doing the same thing if not for some political bull****. In vehicles that can run it, sugar cane-derived E85 is much cheaper and has an overall lower environmental impact than running pure gasoline or E10.

lol... no, I was serious! You guys use ethanol in your fuels and yet you said ethanol mizes in america... made it sound like you're still using pure petroleum. Nevermind. Still wouldn't mind moving to Canada though.

lol no, all of North America. You can get ethanol-free at marinas and Shell V-Power 91 at some stations up here. http://pure-gas.org/

what is this little tube, please?
Hi I was wondering if someone could tell me what this (broken) thin little tube is for. It's by the windshield squirter reservoir. There are 2 of them, just little straw size tubes. This broken one is supposed to connect to a module of some kind (says made in Mexico).
Is it part of the squirter system? My front squirter has only been working intermittently for a long time. Or, is this something totally unrelated?
Also, I have no heat inside, a slow water leak under the Jeep, and the reservoir bottle (radiator res) was empty. Overheated on my way to work today. Luckily it was freezing cold.
Does that sound like a bad thermostat?
So really I have 2 questions: about the little tube and about the cooling/heating system. I've found quite a bit of info re: heater core, thermostat, etc....so really I'd be appreciative if someone could tell me about that little broken tube.
thanks!

Thats a vacuum line for you heater control valve - lets coolant into the heating system, which is why your heat sucks.
As for the overheating your radiator is probably frozen

I have a question:
1989 MJ 4.0, manual, 2wd.
Is the fuse box interchangeable with an XJ? What years work? Is the fuse box all one piece with the dash harness or does it disconnect?
I'm thinking that they are interchangeable except they'll have extra circuits for the rear doors and lights. 88-91? I'm also thinking it's all one piece. Fuse box/entire dash harness. Correct?
Finally, do you have one for sale? Friend of mine needs one.

Was that supposed to be an answer to my question or a freakishly similar question?
Btw, I'm referring to the fuse box under the dash.

first time
I've read threads until I'm blind! my 99, 179,000 runs like a champ and then 3 weeks ago wife took to job interview in snow storm she said "almost died" check light comes on and motor jerks, light off motor recovers does couple times. I drove that morning was fine. read a bunch of threads FUEL PUMP,CPS,ELECTRIC GREMLIN. one guy suggested start simple , I tuned it up was due and had everything in garage. Ran for week no problem started up one evening about an hour after shutting off and motor fires then dies, never does that, quarter mile down road check light on motor jerks then right back on does this 2,3 times real quick mash the throttle no more problems. sits for a couple days. Read more threads think may be electric check out what i can visually find the harness going to rear defrost, wiper is in pretty bad shape ie,boot dry rot wires bare. She's back running great no problems friday put 200 miles on saturday go to wrestling tourney sits for 7 hours starts up, pull out, stalls completely, crank wont start mash throttle , fires wont run unless throttling. have to throw in neutral at stop lights to feather throttle cuts out couple times, light on, motor jerks speedometer starts falling then recovers light goes off. checked fuel pressure 46lbs at fuel rail dropped a pound in 20 minutes. tried to get to auto zone to check obd codes but afraid wont make it and temp is around -10 right now. tried the key on odo button diagnostic but it runs thru the bells and whistles and shows no codes. going to try and rent scanners all out right now. open to advice this is my DD leaning towards cps now but want to check for codes first. thanks
