Do you guys think that it would be safe to install a larger fuel tank on the xb?

 

Why do you want a larger fuel thank?

 

Yeah??? Reason would be????

 

i'd love to go 600 or more miles on a tank.

i used to drive a truck that went 900 miles between fill-ups

 

what like a big rig?

 

I CAN GUARANTEE that a bigger fuel tank would void your warranty!

 

yes like a rig. international 4900 35' flat bed (think tow truck, but bigger)

i really cant see why having more fuel would void my waranty.
remeber that they would have to prove that the bigger fuel tank is the cause of your problem.

 

I want an aluminum tank but just to shave weight. If I could get one bigger that weighs less it'd be cool.

 

I've been under my box a few times. Looks like the tank iss undder the rear seat and pretty much fills up the space.. so maybe an aux tank someplace... I'm with you though.. it gets 33ish mpg, but only holds 10 gal, so I'm still filling up every other day. I have a 72 chev that can hold 60+ gal. I could fill it up in NY and drive all the way to SC. pretty cool.

 

I've never understood why most car manufacturers seem to want to limit you to around 300 miles ... I guess it makes you get out and catch your snap on long road trips, but when you're just driving around town, who wants to fill up that often?

Bring on the bigger tanks!

 

only 10 gallons.. that really sucks... BRING ON THE BIGGER TANKS!!!! someone needs to post a mod for this

 

LOL.

1) jack the car up

10) put flames out by stop, drop and roll technique

 

I love my xB, but like others on this post I hate having to fill up every other day! Any ideas on installing a larger fuel tank?

 

As far as your conversion is concerned, the bigger tank would mean you would have to change or add a new sender so it read properly. The extra weight would also affect your performance, impact your suspension, make items under your car wear sooner. All those things could be attributed to your fuel tank and help void your warranty.

Engineering a car to hold more fuel would mean higher costs and besides, for every person you know that drives 50 miles or more a day there are probably 5 that don't drive 50 miles a week.

Needless to say any time you make changes to a vehicle beyond its designed purpose you do impact other items that can become problems in the future.

Still 500 miles between fillups would be cool, it may also have a psychological factor we are not thinking about .

 

btw, the tank is 11.9 gal. if you are filling up 10 at a time, drive an extra 60 mi

 

You seem quite certain about this. Do you understand the Magnusson-Moss Warranty Act of 1975? My understanding is that it says something to the effect that a modification to your vehicle could end the warranty on only those parts, or possibly the affected systems. But changing the fuel tank would be highly unlikely to affect your warranty on, say, your steering or braking systems unless they, too, were modified.

A quick search finds this online:

 

Something as simple as a gas tank could void your brake warranty. Again, you are increasing the overall weight of the vehicle which will impact certain systems, like your brakes. I saw the dealer tell a friend of mine that his brake rotors were not defective because they were wearing every 20K miles, the result was that the combined weight of him and his wife were the contributing factor to the failure of the part.

Combined they weighed close to 900lbs, and therefore were blamed for the excess wear and no warranty for you .. Cruel, but true in there case.

 

You make some excellent points, but I think that if you keep the additional weight below the vehicle's safe carrying capacity (payload allowance is what...about 850 lbs?) you should be OK (safety- and warranty-wise). Gasoline is around 6.5 lbs/gallon IIRC.

Also, if you could hang a secondary tank at the same level as the original tank, and the two were joined so that fuel could easily flow between the two, a new sender might not be needed.

 

I would try to talk to the guys at www.supertanks.com . Bigger tanks are thier bussiness. All of thier tanks use the stock pump and or sending unit. Sure they only do full size pick ups, but that may be because nobody else asked them to make anything else. If you can show an interest They might at least look into it.

 

Personally, I don't see a need for more range. After 300 miles I'm ready for a potty/food/smoke break anyways. LOL
Plus all the extra weight of the extra fuel will surely cut down the mpg's.
