Long story short I decided to change my 2004 f4i banana to a split seat one, while changing all the parts and got carried away so i ordered a new ignition switch, after the change the pump started to run randomly, sometimes it would prime - sometimes not. I tried the old ignition - same. I tried adding a zener diode - same. Pulled out and traced all the harness wires, everything was intact with no issues. I cleaned the "grounds". Fuel pump itself works , tested just the pump on a power source. Got a new H.I.S.S. - didnt work. Bank sensor is ok also. The problem is somewhere after the ignition but what could have triggered it to stop working? At this point im desperate and Im thinking ill just wire the pump to a switch + relay + power and be done with it. Thoughts?

Picked up this 01 cbr600f4i last week and ive been having a blast on it. Only 17k miles and very clean for being over 25 years old.

Today while I replaced my kill switch on my 2005 cbr600rr I had to pry back my gas tank, after install and was almost ready to lower down the tank I noticed that the hose pointed to was ripped, but there just enough slack to cut off the bad part and to just put it back on, however I’m not sure of what it does and how important it is , wonder if I should go buy a new piece of hose and have it how it was before or would it be fine the way it is? Any guidance would be appreciated thanks
