Default Mounting a new gas tank hard?

I've been thinking about getting an awd gas tank for my 95 impreza L fwd.. not only do I get a larger tank (about 2 gal) but it would be somewhat more ready whenever I plan to go awd.

however is it a pita to remove and drop the tank?

Just nuts and bolts. About a million. Everything in the rear comes out - suspension, unhook brake calipers, gas lines, etc. If you enjoy wrenching it can be done in a day.

You have to emphasise EVERYTHING has to come out. The amount of work to replace the tank is enough that you might as well put the AWD stuff in all at once.

I agree with you Storm. I did say everything. EVERYTHING, FOR EMPHASIS! How's that? And yeah, put in the AWD system unless you want to do it twice. To me it was satisfying to do it. In a word, fun.

I did it to have a tank that wasn't ventilated with a giant gash on the bottom. It was NO fun..... Emphasizing NO!

Whassamatta, don't you appreciate lying on your back with dirt falling in your face while you loosen rusted on bolts? Or the gas draining out of the tank, down your arm into your armpit? I thought you were a scooby specialist, hehe.

subaru doesn't sell the bands that hold the tank in place anymore. When you get pissed and finally cut one, like me, you will have to make one yourself. a lot of crap was siezed on my '95 (it was from Maine). You can probably expect much pain and agony like they said ^^

As mentioned....everything has to come out, exhaust, rear subframe, axles, suspension....just to get at the tank. The strap tie-down spots are different, but that shouldn't matter, you'll just have to find the spots where they put a little rubber grommet in the hole.

As hard as it may sound, you could swap tanks in a day.....(with air tools) When I did my conversion, I had the whole rear suspension out in 2 hours or so. With added hands, you should be able to get the tank out, and new one swapped in.

Other thing to note, in case you haven't run into it yet. The AWD fuel tanks have what's called a fuel separator. It's located in the trunk, and is essentially part of the emissions control system. FWD gas tanks only have one vent line coming off of it. AWD tanks have two. They both go into the separator, and then a line from the separator goes to the charcoal canister. You will need a fue separator if you switch tanks. Be aware they are different between the wagons & sedans (at least for the legacy it was).

Or.....you can run a T and just tie all three lines together. The only thing you need to make sure of....if you go this route is to mount that T high enough to reduce the chance of fuel getting splashed/sucked into the vent lines and going into the charcoal canister.

Here are some pics of the lines/separator, etc.

Jeez....you can get that changing oil on FWD Mopar.... Yeah, and rallycrossing sure seems to allow dirt to collect in places you'd never dream.....

It's almost as fun as changing a transmission outside since you have 2 days off from school due to snow!!!!

My Impreza is werid.. I've always wanted to open it up.. but in the trunk under the mat their seems to be a cover in which the Fuel pump & float are in? If anyone have a 95 L if you lift up the mat you will see... In later models of the impreza you have to remove the rear seat to get to the fuel pump right?

Sounds like a PITA for the tank.. Does Subaru sale the tank by it's self? i'm sure I would get ripped off big time.. I can't think of any other place that would already have the tank pulled.

the access panels as far as I know should be in the trunk for newer models as well.

They are all like this, up to the current models. Nothing weird about it. Fuel pump and level are not under the seat, they're under the trunk.

This is a very much PITA swap that no one should consider doing just to get a slightly bigger tank. Don't do work for a swap until you're at least mostly ready to do the swap.

I got mine at a local boneyard....125 and it was in great shape.

www.car-part.com worked well in this case.

I know this is an old thread, but how can you tell if the tank is from an awd or fwd? I'm looking at picking up a '95 FWD L.
