i was just wondering what it would take to put a secondary fuel tank in the trunk as a reserve fuel cell? any body with any knowledge about this would help out alot. thanks in advance

 

why would you want a second fuel tank?

 

Really more fuel? I rarely fill past half way, I hate the extra weight.

 

I agree why do you want another fuel tank to throw off the balance of the suspension? its not hard you just buy a splitter and a second stainless steel fuel line. You will have no way of knowing how much fuel is in the tank unless you get one with a sender unit, and install a second fuel gauge. But why do you want this?

 

I enjoy going on long trips and would just feel better knowing that I have that extra bit. I don't really care much about the weight as I don't track the car at all. Its just sort of a piece of mind kinda thing

 

get AAA instead its much cheaper. They will give you up to 5 gallons some places.

 

Doc is right, you will just throw off the balance in the car. These cars are great handling cars, doing un necassary things such as an extra fuel cell in the back just doesnt make any sense.

Just about anywhere you drive you will be able to find a gas station and just put more gas in, the moeny you would spend loading up a fuel cell could just be used as that emergency gas money.

You wont go over 200 miles without being able to find gas along the way.

 

Considering that a properly kept car can easily cover more than 300 miles with a full tank before the reserve light comes on i really don't see why anybody would need it!
There are 100lt fuel tanks that meet fia regulations for long distance racing though.

 

yeah you can replace it with a 20 gallon armored fuel cell if you really have to have it.

 

Yeah, I definitely think that adding another cell is not a good idea. If you want peace of mind, fill up early if you know you've got a long strech between cities. Never came close to running out of gas on my road trips.

 

I only get about 220-240. Im at work, my cars out back right now with the light on and im at 231. It came on about 2 miles ago.

I have never gone 300, or over 250 for that matter. All the people i talk to out here in Cali say they get anywhere from 200 is the lowest i heard up to 250ish.

I also do alot of short trip driving, 5 days out of the week the only driving i do is 5 miles to work, 5 miles home. And then when i run errands its just city driving.

 

This sounds likea much better idea if you feel you really must have more fuel capacity.

 

I always forget the crappy gas you have there. Short trips don't help either. When i do short trips only i never go above 420km\50l
The op said that he does a lot of cruising though and from my most recent experience (1000 miles trip) you can achieve what I said pretty easily at a cruise speed of around 75mph in 6th gear (4000 or so rpms with an s1 transmission\4.777 final gear)
Of course ethanol percentages in fuel affect your averages but so do your engine's conditions and maintenance.
Since we don't live in deep africa where you have to go across a desert to find a fuel station i believe that worrying about fuel capacity is useless

 

It's because of what they call "blended" fuel in cali. Its horrible for the car, and they claim it helps the environment. But if your having to burn more fuel to go the same distance its a retarded way of looking at it. Get AAA. Its not that expensive, especially a renewal. Here in texas your allowed 3 roadside incidents a year. If that be two fuel ups, and one tire change or vice versa. It can't be 3 of the same. Thats free of charge. They give you 5 gallons to get on your way. Keep in mind though that running a fuel pump dry can damage it. It's a motor designed to run at load.

 

Oh and that roadside assistance number is on our registration stickers on the inside. It's a service Texas does.

 

i appreciate all of your guys input. the 20 gal armored fuel cell sounds a little better than another tank in the trunk

 

I also would have liked our car to have had at least a 20 gallon tank. For a long time I had to fill up twice a work just going back an forth to work. Would it really be that much work to add a small 12 gal tank like the one below in the trunk and just have it flow into the main tank so the gauge wouldn't be an issue?

 

yes. at 6.7lbs per gallon at room temp. roughly 78 degrees. Mind you it weighs more the colder it gets. so your talking about roughly 80lbs of weight PLUS the fuel tank and whats in the line. so your looking to add more than 125lbs of weight easily.

 

I agree, america is retarded in so many ways for an european mind. Well, retarded may sound offensive so i'll say "strange". I guess that making everybody happy is hard so this kind of weird solutions are found.
Anyway before dropping some serious money on this kind of mod I'd rather make my car as fuel efficient as it can.

Since the car won't be tracked at all a longer final gear may help as much as a good ignition system with a 100cpsi cat and eventually a tune, especially if the car sees a lot of highway.
Swapping to a bigger fuel cel means rethinking the fuelling system, adding an extra tank means losing part of the trunk capacity and having extra fuel lines hanging around. A leakage due to a bad install wouldn't be fun at all.

 

This

is because of this


if you are going on a long trip liek the op is suggesting get on the highway and get off when you need gas you will get 300+ miles to the tank

 

by the way i have driven (to and from 7stock) on highways in Cali and managed 340+ for a tank several times. thatts california gas.

and you need it a couple places in cali you can go 300 miles without finding a gas station

 

Best I've done on the road is 300 miles when the light came on. But at my age the controlling event on road trips is bladder capacity.

I do wish the tank was bigger for my daily drive. With about a 40 mile round trip commute plus some weekend stuff, and a dislike for falling below a quarter of a tank, I need to fill up slightly more often than once a week. Not as bad as Expo1's twice a week fill up, but it does put fuel level at a higher conciousness level than I like.

zoom you must have travled out by highway 62 or the old 66 crossing the mojave desert. Thats out where our base was, and yes you can go 250+ miles without seeing a gas station unless you know where they are. But for most of cali its not like that. Crossing highway 40 or 70 though I would fill up at every half tank just incase lol.

 

no most of cali is not like that but it also helps if you are caravaning and trying to prove to Nemesis8 that you can go 340 miles suddenly that last gas station 40 miles ago is looking pretty sweet

 

lol I know the feeling. we used to drive between 29 palms and vegas all the time.
