fiatphil if they have boosted on them then change them
I have left mine on too long, this is I think the third to go.
Maybe you not read past posts. HERE
To be honest I'm pretty dubious about group buys as an aside.
That's another thread though!

Bugger. All mine are Booster ones. Ive checked all the ones i can see fron on top of the engine bay and they all seem ok. Will keep an eye on them for now.

Fully agree with dlongstaff. Smart move is to get a set from JBT soonest possible.

They will Be with you for Wednesday

Thanks JBT. The hoses arrived today, which was good timing as this morning another one sprang a pin hole leak! Which soon became a bigger problem.
I'll be fitting them tomorrow then I can relax.

Two noticeable differences fitting the new hose.
It was very easy to know that they were tight without over doing it as they so much softer than the booster ones so seal without effort.
Secondly, the outer diameter is larger by half a mm.
Cheers. JBT
