Has anyone changed out their gas tank for a larger or smaller one?

I was thinking for a long trip I would like to have a larger gas tank, but it just might not fit.

I have yet to take a long trip, and there are some long streatches of road with few gas stations along the way. For a 1000 mile trip there is one that has near 100miles of nothing. Just have to plan well ahead for it.

Yes, just plan ahead. 100 miles of nothing isn't a problem unless you have less than 1/4 tank. :)

Also, our cars have two gas tanks. TMYK!

I guess you could trade the spare tire for a tank. But then you would have a ford pinto in a rear end collision. Remember those?
I was driving my mother's 1972 pinto when I was 18, and was rear-ended TWICE in two weeks! First time, I stopped for a red light, and looked in the rear view mirror to see a woman driving a station wagon, who at the time, was looking into the back seat, not stopping her car. She smashed the little thin chrome bumper right down to the body and hatch door. Second time, I stopped for a stop sign and was hit from behind by a girl from my school, which we had both just left a few minutes before. The little bumper was really smashed into the body that time. No explosion, just my friend, who was in the car both times, saying, "What is it with you!"

If you look at the underside - the tank goes from under the rear seat up to just ahead of the differential - not much room for a larger tank.

A lot of stuff packed in under the body.

Those black panels above the heat shields and mid-mufflers - that's the fuel tank - it straddles above the driveshaft:

Good idea but very limited space under these cars. Side note, driving from my house in Gastonia to Orlando is right at 550 miles... I got 498 miles on a full tank in my R/T. That was cutting it close!!!

I'd have to see 500 on the trip counter, that's just me.
Impressive mileage.

I got 502 mi - all highway drive and the low fuel light just turned on.

I've done 468 miles before the "pucker factor" told me I'd better find a station with at least 91 octane. I can't imagine not being able to map out gas stops with 400+ mi. of range. You'll have to pee by then for sure unless you're doubling the speed limit................then props, and I understand and sympathize with your dilemma. :browsmiley:

Try riding around the nation on a motorcycle with a 125 mile range and no fuel gauge. That keeps you on your toes, especially at night when gas stations in the sticks are often closed and you have to nurse the fumes to the next town.

And you have to account for riding uphill or into strong headwinds, where you won't get nearly the full 125 miles from a tank.

The real fun on those older bikes was when you forgot to reposition the fuel valve for the reserve tank and realize that 1/2 gallon reserve no longer exists. That's a thrill. Especially at night.

That bike on that 12,000 mile ride taught me the meaning of "topping off.

I would say that you should grab a few 5 gallon tanks, fill them up, fill the tank when you're able but you could have 5-20 extra gallons in the car. Just make sure that you always have those 5 gallons filled and that theyre strapped down so that they don't spill or cause something else to happen. That way, no matter what you have gas but extra fuel will cause your mpg to go down. Either way, better to be safe.
