Te610 2008 Fuel Pump Bar

Hi there,
it’s my first time here.
Till early 2021, fuel pump was running fire. Then some problems showed up.
I had to punch through the right side of the tank when it’s not working sometimes, then it’s gone completely in time.
It’s my dad’s bike and he fixes his bikes himself. He said that he can find one at auto shops.
I assume it’s 3.5 bar and i want to learn how much bar is it. May anyone enlighten me up?
With my best regards

I've heard 2.9 bar is good

is there any 2.9 bar pressure pump as a standart? I’ve never heard any 2.9 bar pump out there. I mean there are 3 bar and 2 bar pump but never heard any pump around 2-3 bar.

630 info but probably the same as 610. Not sure if the pump is the same. http://www.cafehusky.com/threads/te630-low-fuel-pressure-hard-to-start.91885/ 42 psi=2.9 bar

I would get a 3 bar

thanks a lot. I’ll look for 3.
With my respect.
