Hi, need some help with mc19 fuel pump. Had an engine lean right out on back straight at morgan park, fuel pump had died. Bought another motor and new pump(4psi), would not run and battery was being flattened. Hooked remote tank straight to carbs ran well at low revs(lean at high revs). Does anyone know what .pressure .flow rate .current draw .hose size The standard pump was. By the way have you seen the marquez/ race bike at noodle boy turnpike japan. Cheers
Hi Jimmy and welcome. This is the pump I use in my MC-19 with good results. Also check that your pump relay is working. https://www.aliexpress.com/item/Mot...lgo_pvid=aac26730-5ba8-425c-a9a8-80e788fe6e6d
So what happened to this engine that leaned out? Most four strokes will just lose power and refuse to run without fuel.
