Can you mark with an arrow these hoses and the 5T in the previous photograph, where they are sill on he bike. Thanks.
An easy way to assure your yanking on the correct hoses is to remove the one screw that holds the map sensor switch to its mount, The sensor has (1) hose coming straight out of the bottom of it, follow this hose down and it connects to the plastic Tee fitting, once you've identified that, follow each of the hoses to the TB nipple (brass) and you have it.
Don't try to PULL the hoses off of the plastic Tee or you will risk braking it. Pull the hoses off the TB housing (brass nipple) and remove the entire assembly as a whole unit.
You can then put a drop of PB blaster on the connections, wait a second, then PUSH them off the fitting.
Do not try to re-use the lines, as they will have a memory and may cause air leaks.
Replace the hoses with new ones.
I am available on the white courtesy :call: if you have any questions, or would like to chat tomorrow.
