in tank fuel line couplings

I sure could use some help. My 2010 FE 450 has the intermitent dead fuel pump issue when it gets hot.
placed order for new pump today with CV thermal blanket. My deal is i can't figure out how to get the fuel
line couplings inside the tank apart. they have a gray ring around the connection. there are flat spots on the
od of the gray piece. I messed with it for a while and stopped before I did damage any words of wisdom would
be geatly appreciated. Thanks

that's what i thought a special tool. My Husaberg technician at the dealer said they were quick disconnect fittings.
so after reading your post, and the info from the dealer i gave it another go. one came apart as a quick disconnect, but i wouldn' call it quick. what a pain. the second one i use a small pointed tool per your sugestion
and got them apart. tougher than i thought it should have been, just glad i didn't break anything.
thanks for the help. waiting for new fuel pump. ordered CV thermal blanket. thinking about icing fuel before ride.
I also have the exhaust heat wrapped.

thanks for the heads up on the right tool. my boots are wore out from last outing with fuel pump going dead.
running 2nd in the Florida FTR series when pump locked up and i was done. I was enjoying the best run ever. Read some of the threads on this site with regards to 2010 FE 'Berg fuel pumps. There have been issues with the pump locking up when it gets too hot. They commeneted the internal clearances are a little too tight for the temps the pump operates at. my fuel was boiling good when it stopped running. I had gone down and bike was laid over on about a 30deg angle with tires high and still running, back side of berm. I think the pump may have dry ran a bit and finished it off. You will know if it's a bad pump. jog the starer, normal operation you will here the fuel pump energize. when it's locked up you will here a relay pop under the tank, part of computer, but no sound from the fuel pump, dead. no EFI lights flash. just dead pump. Let it sit, it will cool, and then it will start. mine came back to life after a mile push back to the truck. my Dealer has a warranty claim in with Husaberg for the pump. if you hear the pump run, then i believe it could be dirt. it's died on me 3 different times. if it sits in the garage for a while it will fire right up, like the next morning you tear into into it to fix the problem Runs fine, you think all is well, not the case. I'm replacing the pump as i can't take any more DNF's and long hikes. the guys on this site claim that once they replace the pump problem fixed. It will get worse over time. i have 15 hours on the bike, it started at 9 hours. I'll let you know if the new pump cures the problem and how they handle the warranty.

Where might one find the right tool for the connectors ? no experience in this area. thanks

thanks so much for the advise Haskell and Dale "E"O. we have a snap on truck that stops by work here.
I'll be picking up the snap on pliers. I'm not counting on warranty for the pump, but thought i would ask.
Shoals outdoor sports in AL have been great guys to work with, so we'll see what happens.
13 miles? walk, dang, i was belly aching about 1/2 mile. you are right about this bike, it's fantiastic, i love it,
i'm coming off a 08 yz450 and that bike hasn't been started since i bought the 'Berg.
you are right about the forums i have learned so much from the people on this site.

I had TF Racing in Myakka City www.tfsuspension.com respring it for a fat boy, 230lbs and
he revalved the rear shock, no charge, as he said he learned something about them.
it handles unbelievable. i would never know there is no rear link in the back.
This thing turns like magic, it is sooo fun to cut underneath the 450 jap bikes in corners as you
know they are going wide, nothing they can do. I'm not sponsored by them but you can't go wrong with SOS
and TF. Looking forward to getting this behind me and riding.
How have you guys found the valves holding up on the 'Bergs?.
my yz has 120 hours on it, new piston, rings, cam chain at 100hrs, but valves were still in spec. I chug the motor.

Thanks again for you help guys.
