2008 Suzuki gsxr 1000 how to change fuel pump, fuel filter and fuel pressure regulator the right way make sure you guys do your research. I made a mistake listening to eBay seller saying that a 3.5 bar pressure regulator would work with my bike. It messed up my spark plugs and caused damage to the motor because a lot of misfire bike running too rich on fuel, burning out my spark plugs and causing a lot of fire coming out of my exhaust.
