Review on 🔧 HFP-PR8 Yamaha WR250F WR450F/YZ250/YZ250FE/YZ250FX Fuel Pressure Regulator Replacement (2012-2018) by Trevor Blazis

My WR250R stopped working properly one day and refused to start the next day. The spark was good, the pump ran (louder than normal) but I had no flow through the nozzle. Took the pump out and replaced the factory pressure regulator with this unit and it caught fire right away. The only downside was that the stem that goes into the fuel pump wasn't stamped perfectly concentric, making it difficult for the block to sit as completely as the stem. I twisted it until it was as straight as possible and it seems to work fine. It also came with a small strainer that the original didn't have and that didn't seem to fit in the fuel pump housing. Since the pump itself is filtered, I just didn't use a strainer, which didn't seem to have any ill effects. Will update when it stops working, but so far so good
