Sunsong Power Steering Return Line Hose Assembly P/N:3402308
Keep power steering fluid flowing back where it belongs with the Sunsong power steering return line hose assembly, part number 3401778. It is a direct-fit replacement for the return line running from the steering gear on the 1970-1972 Ford F-100, F-250 and F-350. See the Buyer's Guide tab for engine details.
The return line carries low-pressure fluid away from the steering gear and back toward the pump reservoir, which completes the power steering circuit. Sunsong is a vertically integrated maker of automotive fluid transfer hoses and lines, and it designs its return assemblies around what installers need.
A return line may need replacing if fluid seeps or drips from the hose or its fittings, if the power steering fluid level keeps dropping, or if the hose is cracked or swollen. Find the source of the leak first. If the original return line is the cause, this assembly replaces it.
