    It may be the wrong direction, but has anyone tried to add an extra fuel tank? Or maybe swap the oem one out with something larger?

    I put on a lot of miles and it would be nice to fuel less often.

    It could be just a personal weakness, but I can't drive over 450 miles without needing a restroom anyway,
    I blame Lasix.

    In the top thread about Hybrid news, you will see some recent discussions of nat gas flex fuel including some countries (Argentina) adding a nat gas tank to the Prius where the spare tire goes so you could have nat gas or propane there for extra miles. These types of conversions are quite common outside of USA in Europe etc.

    Well
    One thing is for sure Toyota realize the flaws with Gen2 "bladder" surrounded by metal tank is no easy vehicle to service!:cool: I have replaced fuel tank and pump on other vehicles and would be relucant to attempt Gen 2 Prius because of bladder.

    Extra fuel = more wt = less mpg. I used a 96 Geo Metro 3 banger as a delivery vehicle and found that every 100 lbs was worth 1 mpg. I am sure that more wt would be needed to equal 1 mpg on the Prius. The less power you have the more that wt would mater. I was thinking of using a 5 gallon fuel cell on the old Geo, but sold it....now I am thinking of putting one on the 95 Neon that gets 46 mpg....I drag race it too.
