Upgrading the fuel tank capacity on a gen 2 prius, is it doable?

i suppose anything is possible, but i doubt that it is practical, and i have never seen it done.

 

I don't know why you would want to increase the capacity, the 40 ltr tank in my '06 prius returned 700km driving at hwy speeds ... and my bladder needs a service stop by then :lol:
If the bladder thing they use in the USA is giving you problems, try to find a tank from a Canadian model that doesn't have a bladder, or from England or even Australia ... although the freight might be a bit of a head spin if it's anything like trying to get things from the sates delivered to Australia ......

The fuel bladder definitely has a significant impact. Depending on the season, my car has a fuel capacity as little as 6 gallons (23 liters) in the coldest days to 9 gallons (34 liters) in the hottest days.

 

Scratch the Canada model from the option list, it also has the bladder.

 

Might have to bite the bullet and buy one from the UK or Australia, the AU one holds 45 ltrs (9.9 imp gal/ 11.9 US gal) maybe a little more in mid summer on a trip, the expanding fuel in the tank blows it up a bit bigger, but it does get hot over here in summer, hot enough to melt the tar on the road ......
I put 40 ltrs av on every fill up because I don't want that annoying " add fuel" beeper and warning bar coming up on the centre screen ....
With the new traction battery, I'm getting between 700km and 800km for the 40 ltrs, depends how heavy the foot gets on the less patrolled roads :lol:

Doesn't the Japanese version of Gen2 have a bladder-less 60 liter tank? That was part of how the hypermilers there achieved 1400 to 1800 miles per tank.

 

Would there be any value in carting around the added weight? But the price might be better than a vehicle dismantler used one from Aus by the time freight was added ...
I was getting 1800km out of 40 ltrs when I had the 76 x 40Ah cell battery in the boot and drove at a max of 80km/h (50 mph) where it was zoned 80 km/h or less and only engaged the ICE when we needed to drive faster. The extended range battery recharged from the solar at home.
When I bought the vehicle from "Jason in OZ" it had 1/2 tank of fuel and 2,500 kms on the centre screen that shows distance on last tank, but he drove everywhere around Sydney at under 80 km/h on pure electric and recharged each night

So, even with plenty of plug-in energy, you didn't match the MPGs of those Gen2 hypermilers without any plug-in?

 

We may have the bladder too; would be good to check.

 

Like I could light foot it long enough to get an extended range from a tank of fuel :lol:
