Trying to fix this problem and driving me crazy .
02 Grady , twin 225
changed all fuel filters on both motors , one runs fine the other runs a few minutes at idle or any rpm then cuts off . had water in fuel and but not now . As long as i pump hand bubble its fine at any rpm. is it possible water made it to low pressure pump and killed . I would think if is broke it should not run at all ? Unless I'm filling vsp tank when i pump bubble . Any advice would be great . It all started with water prob . Thanks in advance !
its possible the feed pump failed.
check the 5 amp feed pump fuse.
if the pump locks up it typically blows the fuse.
if it did then you will also need to clean the vapor seperator and high pressure pump filter.
no tech questions by PM, they wont get answered.
you have to be trusted by the people that you lie to .
