Q: How Serious Is a Power Steering Hose Leak?
A: It depends on which line is leaking and how fast. A slow weep at a fitting is a maintenance item to address soon, but a split in the high pressure power steering hose — the line carrying fluid from the GM Type II pump to the steering gear at up to 1,500 PSI in this kit — can drop system pressure quickly and leave the steering suddenly heavy, especially at low speed or while parking. A leak on the precision power steering return line hose is lower risk since it runs at low pressure, but it will still drain the reservoir over time and starve the pump of fluid if ignored.
Q: How Much Do Power Steering Hoses Cost?
A: A factory-style hose replaced at a shop typically runs $75-$350 in parts and labor, but that assumes a hose that already exists for your vehicle — a Chevy C10 running an LS swap and a GM Type II pump usually doesn't have a direct factory replacement, so a shop has to fabricate a custom line. The EVIL ENERGY AN6 kit covers both the high pressure power steering hose and the precision power steering return line hose, plus six adapters across three thread sizes, in a single kit rather than pricing each custom line separately.
Q: What Are the Signs of Power Steering Failure?
A: Common warning signs include stiffer or heavier steering (especially at low speed), a whining or groaning noise from the pump on turns, visible fluid under the vehicle, and a low or discolored fluid level in the reservoir. On a Chevy C10 LS swap running this AN6 kit, check the fittings on both the high pressure power steering hose and the precision power steering return line hose first — a wet ring at an AN6 connection or a hose bent tighter than its rated bend radius (3.5 inches for the PTFE line, 2.5 inches for the CPE line) is a more likely cause than the GM Type II pump itself.
Q: What Is the Lifespan of a Power Steering Pump?
A: A power steering pump commonly lasts around 100,000 miles or roughly 7-10 years under normal conditions, though heat, contaminated fluid, and running the pump low or dry from a hose leak can shorten that considerably. The hoses feeding a GM Type II pump matter almost as much as the pump itself — a compromised high pressure power steering hose or return line can starve the pump of fluid or let air in, which accelerates pump wear well before it would otherwise fail.
Q: Can You Use a PTFE Hose for Power Steering?
A: Yes — PTFE is a common choice for the high-pressure side of a power steering system because it resists heat and power steering fluid better than standard rubber, and holds up in the tight, hot engine-bay routing typical of an LS swap. This kit uses PTFE specifically for the high pressure power steering hose, rated to 1,500 PSI working / 4,500 PSI burst and -76°F to 446°F, while the lower-pressure return side uses a more flexible CPE hose rated to 750 PSI working / 2,250 PSI burst — using PTFE on the pressure line and CPE on the return line matches each hose material to what that circuit actually needs.
Q: What Different Types of Power Steering Lines Are There?
A: There are primarily two types of power steering hoses: the high pressure power steering hose (pressure hose), which transports fluid from the pump to the steering gear or rack, and the low-pressure return hose, which carries fluid back from the steering gear to the reservoir. This kit builds both sides of that circuit — a stainless-braided AN6 PTFE high pressure power steering hose for the pump-to-gear line, and an AN6 CPE precision power steering return line hose for the gear-to-reservoir line — rather than supplying only one half of the system.
Q: What Size Power Steering Hose Do I Need for a Chevy C10 LS Swap?
A: This kit is built around AN6 (6AN) hose for both lines — an 8mm-ID PTFE high pressure power steering hose and an 8mm-ID CPE precision power steering return line hose, each about 25 inches (roughly 27.56 inches with the pre-installed 90-degree fitting) before any trimming. AN6 is a common size for GM Type II pump pressure and return circuits in a Chevy C10 LS swap, but always confirm the port size on your specific pump and steering gear rather than assuming AN6 fits every combination.
Q: Do I Need a Power Steering Hose Diagram Before Installing an LS Swap Kit?
A: It helps, especially since a Chevy GM power steering hose diagram makes it obvious which port on the GM Type II pump is pressure and which is return — a detail that's easy to mix up without one. If no factory diagram exists for your specific swap, the general rule holds: the high pressure power steering hose connects the pump's pressure port to the steering gear or rack inlet, and the precision power steering return line hose connects the gear or rack outlet back to the pump reservoir. Confirming this before connecting either AN6 line avoids having to redo the installation.
Q: What Adapters Do I Need to Connect a GM Type II Power Steering Pump?
A: It depends on the exact pump and steering gear or rack you're running, since GM Type II pumps and steering components show up with a mix of metric and SAE ports across different builds. This kit includes six AN6 adapters covering three thread standards — M16 × 1.5, 11/16-18 UNF, and 5/8-18 UNF — so you can match the high pressure power steering hose and precision power steering return line hose to whichever port style your pump and steering gear actually use, rather than assuming one thread size fits every GM Type II pump.
Q: Is a High-Pressure PTFE Hose Better Than a Rubber Return Hose for Power Steering?
A: They're built for different jobs rather than one being universally "better." The high pressure power steering hose needs to handle the pump's peak output — this kit's PTFE line is rated to 1,500 PSI working / 4,500 PSI burst and up to 446°F — while the precision power steering return line hose only needs to carry fluid back at low pressure, so a more flexible CPE construction (750 PSI working / 2,250 PSI burst, 2.5-inch bend radius versus 3.5 inches for the PTFE line) is easier to route through a crowded Chevy C10 engine bay. Using PTFE on the pressure side and CPE on the return side, as this kit does, matches each hose to its actual operating conditions.
