Might be lucky this time, But watch it...

I replaced all the heater hoses on mine last weekend due to a long standing heater problem which had finally ended up with no hot air when the heater was up full, The problem was the heater tap was stuffed.

I brought a new heater tap from Repco for $30.

I also got the right hoses from Supercheap Auto to finish the job.

I also brought a bottle of Tectaloy Xtra Cool Gold for about $20, 1l treats 15l of water.

Tectaloy was recomended in Max Ellory's repair manual for the EA-ED series.
