MikeRL411 Posted September 15, 2010 Report Share Posted September 15, 2010 Blew my firewall heater hoses! Ever try to order preformed hoses for a 43 year old car? So I made my own. Here's what you have to deal with, a heater inside the passenger compartment and 2 preformed hoses behind the motor in the engine compartment [firewall omitted for clarity]. So first go buy these parts:- 2 each Gates 18423 half inch preformed hoses, no they don't fit without modification 2 each "Watts" half inch hose barbs A-380-LF Home Depot in the garden hose area. 2 each "Orbit" five eighths Repair Pro Mender part number 27945-11rC, again Home Depot stocking number 258 584 Cut the Gates hoses just beyond the short right angle bend, one inch did me fine. Splice the uncut ends with a half inch hose mender for the long hose. Splice the short cut end to the uncut end of the long piece for the upper short hose. Force a five eights Pro Mender into the longer end of the just formed hose, I know 5/8 into 1/2? It will go, lube with a drop of antifreeze if it makes you feel better . Now go skin your knuckles attaching them to the firewall half inch fittings! Quote Link to comment

MikeRL411 Posted September 16, 2010 Author Report Share Posted September 16, 2010 For the final connection a five eights to half inch adapter barb would have been perfect, but I could only find five eighths to three quarter. That's why I had to jam the five eighths into the half inch hose end. Also, I tried a cut off section of half inch copper pipe for the intermediate connection [sharp eyes will see one in the second photo] but hose tension kept squeezing them out of "battery", so I went with the barbed connectors.
