I have a 02 rc51,it’s been sitting 15 yrs ... decided to get it running 🤷🏻‍♂️
cleaned fuel tank, replaced fuel pump with a quantum pump and filter...
Put tank back on and even with the fuel pump unplugged, the bike floods out and cylinders fil with fuel
Any one help 🤷🏻‍♂️

Thanks buddy

should fuel pass through the pump and into the the injection with out the pump running ?
when I take thefuel line off the tank fuel runs out the bottom is it supposed to without the pump pressured ?
when I crank it with out the pump plugged in it gust fills the cylinders

The only thing that will flow when unhooked is the return line.

If you have the pump power disconnected. Even if there was fuel in the line, your injectors wouldnt work properly with no fuel pressure, so it's not like you could flood it.


Just try what I suggested first.

Thanks my friend, I ordered a new FPR last night . There was fuel in the vac line but when I crimped it same problem existed.
with the fuel pump unplugged kill switch off, spark plugs out raw fuel shoots out exhaust...
The bike only has 700 miles been in my living room since 03 lol
Thanks again for your help ... I’ll let you know when I get the FPR in👍
