When I did mine it took 28 ft of the 1 1/2 hose and 8' of the 3/4 for the vent hose. Mine had the y valve and divirter also, all original. I still am regrowin skin on my knuckles 3 years later. Be prepared to enlarge the hose holes with a grinder or other means as the new trident hose I used was a very tight fit through the holes they had for the old poly hoses.
