The white washer you used....under the seat? If so, your needle is not allowing enough fuel flow.
You were told this, looked at the breakdown, yet you still did it?
Just making sure this is what you did.
Pump side? It should all work through one hole, so I don't understand that. Also, hook it all up then do it period. Without weight, your not "purging" anything.
Does the motor and pump sound like it's cavitation when you have failure or does it quit running?
Last but not least, with the motor...
Getting a pic of the actual hole would settle it for sure. If it looks like a hole a manufacturing company would make...it probable is.
Test to see if the overheat alarm system is working...did the motor get hot?
All clues.
Reading through the thread here...am I missing something?
Have you unplugged the control box and jumped it at the motor? Kill circuit, wife overboard clip.
Pull it at night...might see flashes.
If you got hit, something zapping. You might have two shorts or two problems.
Again, wiring is suspect...old and if it got hot once, insulation melts. Seen it more than once.
