Why Choose This Fleece Hose?
For builders and performance enthusiasts who demand clean routing, optimal fit, and high durability, the FPE-34574-A stands out. Unlike generic straight hoses that require bending and compromise flow, this pre-formed hose gives you factory-tight bends, improved aesthetics, and a professional finish. Whether you’re working on a 6.6L Duramax, Cummins swap, or custom turbo rig, this hose elevates both form and function.
Installation Notes
- Ensure 90° ends are oriented away from potential heat sources and allow clearance for clamps and routing.
- Use quality coolant-rated clamps sized for 5/8″ hose. Avoid oversizing or flat clamps that can compress the hose inner diameter.
- After installation, bleed the coolant system to remove air, check flow through the hose path, and inspect for leaks during first hot-up and under load.
- Even though universal, verify your hose end connections match 5/8″ ID fittings and that bend angles suit your engine bay before final install.

FAQ
Is this FLEECE FPE-34574-A hose a direct stock replacement for a specific truck model?
No. This is a universal-fit hose designed for applications where a 5/8″ inner diameter hose and 90° bends are beneficial. It is not vehicle-specific and you must confirm clearance and end connections for your setup.
Can this hose handle high-temperature engine bay conditions?
Yes. The hose is constructed of EPDM rubber and moulded to withstand typical performance engine coolant temperatures and pressures. It’s designed for tight routing, elevated temps, and heavy use.
What clamps should I use with this hose?
Use premium quality coolant-rated clamps compatible with 5/8″ hose. Avoid over-tightening which may deform the hose or restrict flow.
Does this hose come with a core charge or require old hose return?
No. This is a new accessory product and does not require any old hose return or core deposit.
What are typical uses for this pre-formed hose?
This hose excels in custom coolant systems, intercooler bypass loops, retrofitted engine bays, or anywhere tight spaces and clean appearance matter. The 90° ends save routing headaches and help with clean installations.
