I am getting a Edelbrock Torker intake to replace my old Edelbrock Performer. I need to find a fitting for where the heater hose attaches to the intake. My old one is rusted in place and I cannot get it to unscrew. Where can I get a new one?

Any auto parts store will have them. Look in the Help parts section. About $4.00

Any NAPA store handles Weatherhead brand BRASS fittings. They are available for both 5/8in and 3/4in heater hose with 1/2in pipe threads (that is the thread size in the manifold). Unfortunately I don't have the part number for the Weatherhead brass fittings.
