So I needed to replace my fuel tank on my 98 GST because of rust. When I purchased a spare 97 GST fuel tank I thought it was the same. After pulling my tank, it has the charcoal canister in the original tank but the 97 GST tank I purchased doesn't. I can't find the tank I need anywhere, nobody has any idea what I'm talking about. What eclipses specifically have the canister in the tank? Do all 98 GST's have it? 99? Would a GS have it? My GST is sitting at a family members house where I can't stay for much longer! I need to find a tank asap or I have no idea what I'll do with the car.
 
If I'm not mistaken late 98's and 99's came with in-tank charcoal canisters. 95-early 98 came with a charcoal canister in the engine compartment.
 
I can only speak for turbo models as that's all I've owned. I would trek to the local junk yard, or ask someone with a non turbo where theirs is located. Wish I could be of more help.
 
Mitsubishi has moved the 2g charcoal canister (evap emission canister) around depending on the year and whether it's a turbo/NT, FWD/AWD, 2.0/2.4, ABS/noABS (presumably due to the ABS pump location) model. All these cases have shown up in Mitsubishi's real factory manuals (ones published by Mitsubishi). Aftermarket manuals show it, often incorrectly, all over the place or even always in the same place. Locations vary from under the battery, to under the LF headlight, to next to the gas tank, to inside the gas tank. For added confusion Mitsubishi sometimes doesn't even follow their own manuals, especially for 98 and 99 years.

Thanks, you have been a lot of help! I actually do own a 99 GS, but I work all the time. In 9 days I only got one day off and that was BEFORE I realized that the tank was different. Next day off is tuesday, so can't get under my GS till then.

I have an aftermarket that doesn't show the differences sadly. Any links for the manuals that have the info?

Not sure if my GST has ABS since I seriously just bought it and towed it to a family members house. My 99 GS doesn't have abs. Anyway I can still use the 97 GST tank? I found a place where they will sell me the correct tank for $150 shipped but I already spent $50 on the 97 tank so I would be $200 deep and I already owe my mom $400 for registering the car for me and I am broke till next pay check.
 
Depends on how much work you want to go through. Engine compartment charcoal canisters have vent lines running up to the canister and back. Sure, you could keep the tank you've got, but then you'd have to source an engine compartment canister, vent lines and vacuum lines, and then connect them all up.

Since you already have a running car, just be patient and save up and order the right tank. You might be able to sell the first tank you bought to a local dsm'er.

Yea that would be more of a hassle really.

I don't have time to be patient sadly, if I can't get it locally in a week I will be forced to dish out the $150.

Anyone know where I can find the diagram with part numbers? I need 4 of the hoses for the tank but can't find part numbers anywhere. The printout that the dealer gave me for the vin shows the wrong tank...

Thats crazy man. I wonder how that all happened. Mines under left headlight. Well it used to be.
 
Man it's stuff like this that makes me glad we dont have emissions here. I threw all of that sh** straight into a box as soon as I could. If it didnt get thrown away i'd consider selling it.
We don't have emissions here either thank god LOL But based on my understanding removing this will slightly lower my mpg. This GST will be a daily driver soon and me boosting around town will already kill my mpg enough LOL


WHERE DID YOU FIND THIS? Thank you so much! The dealer couldn't even provide me with the correct print out. I would love to know where I can get these diagrams myself so I don't need to bother others?

I need the 3 hoses that connect to the canister. Not sure they are on that diagram? I don't see them. Maybe there is a separate diagram? I also need the single hose next to the canister. Not sure what that is, but it looks like it's part #05015B. Once I have the other 3 part numbers I'll order them from the dealer.

Also, I don't really like those factory clamps. Would it be bad to replace them with the worm gear clamps?

This is from the Mitsubishi ASA database (same one dealers use).
Download database here: http://www.dsmtuners.com/threads/dsm-caps-program.470931/#post-153340217.
Or use online version here: http://www.partsbase.org/mitsubishi/us/

Attached is the diagram of the hoses on the in tank canister.

PNC is Part Number Code - it is not the part number. Example: PNC is like the generic code for a fuel pump where the part number is the actual number for the fuel pump used on a unique year, model, engine, options, latest revision etc. (and is often stamped on the part and is what you order it from Mitsubishi by). Part numbers usually start with MB, MR, etc.

The 4 hoses are:
PNC 5617D, PN MR323718
PNC 5963T, PN MR299442
PNC 5963S, PN MR266607
PNC 5015B, PN MR342240

Ya worm gear clamps are ok as long as the gear teeth don't dig into the hose.

Thanks for the links! My computer won't boot into Windows atm only Mac so I'll use online version for now. I favorited both links.

Thanks for the diagram and part numbers! I'll put in the order for those hoses in the next few days. My only free day was yesterday but they called me in for work because they were short staffed.. So I'm taking the $150 hit and ordering the tank this week.

Question about the database. First, what's the difference between GS-T, 5FM/T FED and GS-T, 5FM/T CAL?

Second question, how would I have known my car needs this specific tank if I had not taken it out already? If I need another diagram how would I know it's correct for my car? For example, I took a look at the GS and it has multiple tanks as well. How do I know which one my 99 GS needs?

Note that you can get the oem parts cheaper here (even with shipping) than your local stealership. If you know the PN, just enter it in the provided space. If you don't know, either go through their proceedure (time consuming to find it) or use the ASA database (faster):

The easiest way to use ASA is to enter your VIN in the ASA database. That will select the things your car came with. If you don't know the VIN, first select the correct Model and then the Classification choices in the ASA database (which can get confusing if you don't know what the abbreviations stand for - experimenting and experience helped me). Then select the area of interest (engine, pwrtrain, etc). Then the square of interest (note: when you want to go to a different square, you have to uncheck the previous one or it will keep going there). Then the item (which is the PNC number) which will bring up the part numbers. If you select a part number and click PNC (at the top), it returns to the diagram. A couple left arrows gets you back. To start completely over click the All Clear icon at the top or under Edit. When showing the diagram, sometimes in lower right corner there is a "Page" to select which shows different versions of the part for different configurations (Cal vs Fed, AWD vs FWD, NT vs Turbo, etc) although it doesn't always tell you which is which unfortunately. And when you finally select the part, it may show different PN's for different years (so you may need to know the month/year the car was made - sticker on door edge). [Note however that ASA build dates use the format xx.yy.z where xx is year, yy is month, z is which 10 day period of the month.]

So I do the best I can but then also visually compare my part to the diagram even if it's still on the car (it's very rare but Mitsu sometimes changes a part at the last minute before they ship the car which didn't make the ASA database). Visual example: removing the LR wheel and looking on top of the gas tank (with a flash light) showed me I have the vapor canister inside the gas tank instead of at the many other places it appears.

Thanks for the tip I'll compare those prices with dealer prices and see which one is best!

Thanks I'll try getting my pc running so I can install the database and use the Vin search. I never thought it would be different so I guess it's my fault I never checked my tank before purchasing a used one. I'll be sure to verify with the database and visually which part I need next time!

Thanks for all your help! I'll hopefully have everything ordered by this weekend! Once I'm up and running I will update my profile LOL
 
So much work for maybe 1 mpg.. emissions in our cars are seriously useless. Even if you do get all the emission lines and sensors hooked up correctly, a week later a sensor will decide to crap out or a random CEL will pop up for emssions. I for one could never get it to function correctly so I tore it all out and in the garbage it went. I'm surprised someone here hasn't tried to stop you from wasting your time.

Good luck tho Merry Christmas :)

I'm surprised too. I really rather keep it original anyway. If I put the 97 tank in I would still need to run the hoses from that tank because I can't just keep a hole in the tank and the car only has the hoses for the in tank canister. I have time to google parts and such while at work, but I don't have time to sit under my car and try and figure out how to use the 97 tank I rather just buy the parts I need and install it in an hour or 2 after work one night.

I have a CEL that I'm not even sure of yet LOL The seller told me what it was but I forgot. I know I didn't care at the time so it can't be that important. I'll check it once it's running.

Thanks, Merry Christmas to you as well!
 
$101 for 4 hoses?! WTF?! This is crazy! Makes me regret cutting them off! How in the world is one hose $48...

$250 to get this tank replaced is a little much. That's still without the clamps, new pump, new gas. If anyone can help me out and has any ideas please let me know.

No this is a DSM! You didn't think the parts were cheap did you? They will be even more pricey at the stealership.
When it comes to a set of hoses I wouldn't expect to be spending $100. It's really the only option?

If it is, then I'll go for it. Just really don't want to.
 
I don't know if it's the only option, I've never had my tank off or worked on the canister. The OEM hoses will be all pre-bent to match all the chassis (and stuff in the way) bends perfectly (so it's nice and tidey). Perhaps you can cut your own hoses and make them work.

Does anyone have any experience with replacing these hoses to help him out?

I don't know if the hoses have to be a certain type and I'm not sure the diameter.

Hopefully someone has experience and can help me.
 
Anyone know if I'll need another canister? My old tank is very rusted and I'm not sure if the canister can be re-used.
 
Quick question, is there just vapor going through the canister hoses? I received some used hoses along with the used tank I ordered. The hose that runs back to the engine was cut short and one of the other ones has a split right at the end of the hose, it shouldn't leak.

Would it be fine to run the car like this? I'm worried about the hose that leads to the engine not being connected. Will vapor just come out to the atmosphere and all be fine? Or does any fuel come out?
