just bypassed c/b with spade type 20 amp fried it in 7 sec its on the way to the dealer

brought it to dealer they say it had bad fuel pump that was shorting out. thats why the c/b popped.
got it home tried starting and fuel just pored into carb. called dealer he says i must have contamination . i think the new fuel pump is the issue? now it goes back monday.

ok brought back to dealer they could not find problem. They opened the carb and found float was a bit sticky. I think the 40 miles each way of towing on back roads and an empty carb may have bent something internal. working fine now
