LS Conversion Fuel Injection Line Fitting Adapter Kit EFI FI & Filter Regulator

EFI Fuel Injection Line Fitting Adapter Kit

This EFI fuel injection line fitting adapter kit provides the fittings, filter, and regulator needed to plumb a fuel delivery system on LS conversion builds and other electronic fuel injection projects.

Overview

This fuel injection line fitting adapter kit is assembled for builders converting to electronic fuel injection who need reliable connections between pump, filter, and rail. The kit pairs adapter fittings with an inline filter and regulator so a complete feed circuit can be laid out in one purchase. It suits LS swap projects, restomods, and universal EFI plumbing where thread and hose ends must match.

Built For Performance

• Adapter fittings sized to join EFI fuel line components
• Inline filter included to trap debris before the injectors
• Regulator included for setting and holding fuel pressure
• Kit format reduces the number of separate parts to source
• Suited to high pressure EFI circuits rather than carbureted low pressure systems

On-The-Job Use

• Plumbing the feed side of an LS conversion swap
• Rebuilding the fuel circuit on an EFI retrofitted classic
• Adding filtration and regulation to a custom EFI tank setup
• Servicing an existing EFI line junction with fresh fittings

Good To Know

Q: Do I need to know my line and rail thread sizes before ordering? A: Yes, thread and hose end sizes vary between builds, so matching them to your pump, filter, and rail avoids returns. Measure the existing connections first.

Q: Is this kit meant for carbureted fuel systems? A: It is intended for EFI circuits where higher pressure and filtration matter. Carbureted setups generally use lower pressure components and different fittings.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
