    Looks like you have a "L" right angle fitting there, and then your fuel hose has to go UP HILL to the Carb. As long as you have a bit of fuel pressure (head) in your tank, it's likely you can use most ... but maybe not all of remaining fuel in your Safari.

    QUESTION: Does the Safari not have a reserve? If not, perhaps you could fit a different Petcock ... one with a reserve intake that is LOWER than the current one in the Safari. This should give extra range.

    Question 2 : Does the Safari have TWO petcocks? (right and left side)

    I went through similar problems with my IMS tank. I also had to remove an inline aftermarket filter and had to rotate metal Carb intake pipe. All this helped, along with cleaning my dirty Petcock filter. But on your NEW tank should not be an issue ... yet.

    I've retained the stock Carb inlet filter in the metal tube ... but I carry TWO
    spares when on the road. One load of bad gas will CLOG this tiny filter ... so keep an eye on it. Usually it can be easily cleaned. Sometimes not, hence carrying a spare.

    Now ... with my IMS tank ... I can go to about 220 miles before reserve. And what was once just 10 to 15 miles on reserve is now up to 32 miles.
    Cleaning the petcock made the BIGGEST improvement. So now up to just over 250 miles until DRY. (although still about a 1.5 liters left unused) Not perfect but better. 220 miles is fine for me and what I do. PLAN AHEAD! :lol3

    Good luck!

    Looking at my Acerbis4.9 tank, it appears that the petcock actually sits below the level of the intake on my carb. Anyone else notice this? I can't actually hook up the fuel line without there being a bit of an uphill climb to it or a bend.

    Don't know if this could help, but... I have pressurized the gas tank on my ST1100 with lung power and piece of hose to get fuel to the carbs when the 'lectric pump failed. Not recommended for a long trip, and do remember to remove the hose from yur mouth before ya inhale. :huh

    Is this an IMS or Acerbis tank? Seller claimed to be acerbis. But look IMS to me. I think acerbis is more angular, correct?

    I just purchased the acerbis tank and it looks the same to me. You will know for sure when you fill it up.

    This seems to be a common problem. When I fitted mine I had it the same as yours and when I hit reserve the bike would die even though I had changed to reserve. I had to blow down the tank vent to get fuel into the carb before it would go again.
    What you need is a longer hose between the T piece and the carb and it needs to loop down and back up to the tank. This cures it. Straight in like you have it seems to cause an airlock. With the hose going down hill there is always some fuel in it.

    My Acerbis tank is a 5.3 gallon. :scratch The petcock is above the intake on my carb, but I have a TM 40.

    Yea, Spoken with the seller. He confirmed it's an acerbis. Only wish He posted pictures of different angles.

    that looks like an ims to me; not an acerbis.

    And I thought changing the oil on my old 520exc was a PITA. Love my dr though suspension no where near that of the old 520...

    :deal I so badly wanted to put my DR650 engine in the chassis of my 2000 KTM 250 exc. That would've been a fun bike.

    Now I think I would just get a 2007 525exc and call it even.

    DR is easier to change oil on.

    That looks just like my IMS 4.9. The Acerbis 5.3 is more angular. The Acerbis 6.6 for older DR650s looks different.

    The OEM Suzuki petcock on my IMS 4.9 was just a hair lower than my carb inlet. Then I turned the inlet.

    Dr oil change is a breeze. Newly purchased 79 xr600 framer should be just as simple. Gotta love simplicity fer sure. Your 250 is a stroke right? Got a 300xcw but she doesn't get ridden much since purchase of the dr and now the track bike in the works. I need to find a way to retire so I can ride em all.... :)

    Interesting. I also think that's an ims tank. may just have to call the seller again.

    I like the angular acerbis more.
