Designed to restore your engine’s performance to original specifications, they are durable, reliable, and come with a LIFETIME replacement warranty. Precision designed with robust engineering for proper fuel pressure delivery, engine performance and resistance to leakage Application specific for the perfect fit every time Fuel pressure is preset to the vehicle’s factory specifications-the fuel supply pressure will be the same as it was at vehicle manufacture Meets or exceeds original equipment specifications in fit, form and function Provides consistent and predictable fuel pressure at all RPM levels Review: This fixed the problem with our XT250 - One day the XT250 wouldn’t start. Or sometimes it started but would quickly sputter and die. I only found one person with a similar problem on Reddit, and decided to throw the part at it and see if it works. If you are even remotely mechanically inclined, this is an easy fix. You just take the gas tank off, remove the pump hose and electrical connection, take off the 6 hex bolts holding the fuel pump out, pop out the fuel pump, and this is the small part being held in with a couple clips at the top. Out with the old and in with the new, done. Bike started right up and runs like a top now. Review: Una botta di fortuna - WR250R ripristinanto con questa valvola. Arrivata in tre giorni lavorativi. Prezzo regalo rispetto al ricambio Yamaha. ## Features - An exact-fit pre-set fuel pressure regulator that maintains required and consistent OEM fuel pressure to the engine - Meets or exceeds OEM specifications in fit, form and function and compatible with modern ethanol-infused pump gasoline.
