I used a wood chisel and hammer to remove those quick connects. Then i used hose clamps and fished the hoses in through the truck. I then used plumbing fittings to flare out to the 1 inch and a half fitting on the block. Between buying those hoses and the disconnect toll I save a lot of money. Did you feel the hoses to see if they were hot? I am glad to hear your truck is all old school. The computer control trucks get better mileage, but they never seem to stay running properly.
