Hello,
i have 2005 polaris sporsman 800 twin efi.
it seems like gas heated too much or something...

if i go to drive forrest after 1hour engine wont run any more and gas smels alot. And when i put my fingers in the gas tank gas feel pretty warm...

i tought that if gas is too hot it start to boil in injection system?

after gas is cold or if i fil tank with new gas its runs ok agen.

anyone have similar problems?

Sorry bad english....(Finnish)
and thanks everybody

 

Sounds like possibly your fuel pump is on it's way out...

did you check the vent lines to make sure ther not blocked or pinched off?

 

my old 700 would do that, it was a carb model, I wrapped the fuel line to the carb with reflective heat tape , bought it at home depo solved the problem, might try it

 

IMHO it would be a real long shot to heat gasoline enough to boil it. The pressures are way higher with an EFI than with a carb.
With a carb it can happen because the gas is at a much lower pressure in the line and is just sitting there in the bowl.

Vapor lock would be the last place I would go with an EFI. A bad fuel pump would be at the top.

 

Thanks everyone i order new fuel pumb and try after that. I tell later do it help or not -Pete-

 

a fuel bump that is going bad usually will act up when it does get warm and once cooled back down it runs better so it might indeed be a pump. good luck and let us know.

 

I hope you are getting an after market fuel pump....Much better idea than having Polaris tell you that you have to buy the whole tank assembly...

WOW.. it was guide expensive in finland.... 599 euros.
Anyone have an idea where i can order aftermarket pumb whitc is good.

thanks -Pete-
