I have had a FASS short out like that too; was warrantied without problem. The brass check valves of the initial design developed a leak, have sourced satainless ones but am leaning to agree that valves will be at least easier to replace. The ones on the engine are a bear. May try a valve switching operation but I had no funtional problems with the check valve operation, just the life (1.5 years/30kmiles) (Those valves don't last forever either). I am going to try a Raptor pump if the fass goes again and they release their 75psi version.
