I have the old style Backpack my hose has split at one end it is slightly larger hopefully you can see in picture ,does anybody know where I can a new bit from please

[Smurf]

Just cut it back where it has split and put it back on surely 
If it has an insert just cut that out of the bit you cut off. Then use a heat gun to soften the hose up and put it back. Job done!

Or just contact alex to see if they still carry any spares and if so replace it.

I wish it was that easy smurf  it is moulded at one end and cant be cut off heated nothing I need new one

[Smurf]

Can't you do away with that connection altogether and fit a hose directly to the outlet of the pump as that thing was put on for sprayers so is not intended use for wfp work. I'm sure with your diy skills you could have it up and running in no time.

It also makes me chuckle that alex charges extra for a sprayer too as after all that's all they are a blooming backpack sprayer modified for wfp
