KPALAG EFI Fuel Check Valve Assembly for Harley 2003–2007 — Brass Couplings & PA11 Hose

KPALAG EFI Fuel Check Valve Assembly is a direct-fit replacement fuel check valve and hose kit for 2003–2007 Harley-Davidson Road King, Road Glide, Electra Glide and Street Glide models (Replace# 62228-03).

This replacement assembly restores one-way fuel flow control in EFI-equipped Harley-Davidson touring bikes, using corrosion-resistant brass quick couplings and an upgraded PA11 fuel hose. The kit arrives ready to install with clamps included and is engineered to resist aging, cracking and fuel-induced degradation so you get reliable operation back where the factory part wore out.

How does this assembly restore proper fuel flow?

The check valve enforces one-way flow so fuel cannot siphon back into the tank or feed line when the pump is off. Brass quick couplings seat precisely to prevent leaks and the internal check mechanism opens only under pump pressure, closing when pressure drops.

• Brass quick couplings with nickel plating for tight, leak-free connections
• One-way check mechanism compatible with EFI fuel pressure ranges
• Seals and hose designed to reduce fuel seepage and vapor loss

Will this part fit my 2003–2007 Harley model?

Yes — the KPALAG EFI Fuel Check Valve Assembly is manufactured to match fitment with Harley-Davidson Road King FLHR, Road Glide FLTR, Electra Glide FLHT and Street Glide FLHX model years 2003 through 2007. It is supplied as a direct replacement for part number 62228-03.

• Explicit fitment: Road King FLHR, Road Glide FLTR, Electra Glide FLHT, Street Glide FLHX (2003–2007)
• Replace# 62228-03 compatibility confirmed by design and dimensions
• Includes clamps for straightforward factory-style installation

What materials and improvements does this kit use over the original?

The assembly combines nickel-plated brass quick couplings and a thicker PA11 fuel hose to boost longevity and resistance to corrosion, fuel chemicals and UV. PA11 provides better flexibility and impact resistance than many common fuel hoses, reducing the likelihood of cracks or brittle failure.

• Nickel-plated brass couplings for corrosion and rust resistance
• Thickened PA11 hose: elastic, aging- and chemical-resistant
• Supplied clamps secure the hose to OEM-style fittings

How simple is the installation and what’s in the box?

Installation is designed to be straightforward for technicians or mechanically capable owners: remove the worn check valve and hose, attach the KPALAG assembly using the included clamps and verify a snug, leak-free connection under pressure. No additional fittings are normally required for the listed Harley models.

• Package contents: 1x EFI Fuel Check Valve Assembly, 2x clamps
• Direct-fit design minimizes fabrication or trimming
• Recommended: inspect hose routing and clamp torque after initial ride

Who is this for: motorcycle owners and mechanics rebuilding EFI fuel systems on 2003–2007 Harley touring bikes who need a reliable, corrosion-resistant replacement for the OEM check valve and hose. Choose this KPALAG kit if you want a durable PA11 hose and nickel-plated brass couplings that help prevent leaks and extend service life without complex modifications.
