GlowShift is expanding its lineup of fuel pressure adapter fittings with (3) new Quick-Connect Electronic Fuel Injection (EFI) Fuel Line Adapters designed to simplify fuel pressure sensor installs on modern cars and trucks.

Available in 1/2” or 5/16” sizes as well as a dedicated 3/8” version for 2013-2019 Dodge Ram 6.7L Cummins applications, these inline fuel pressure gauge adapters deliver a clean, reliable way to add fuel pressure monitoring or a nitrous feed without cutting or modifying factory fuel lines.

Each fuel line port adapter features precision-machined billet aluminum construction with a durable black anodized finish that resists corrosion. Our Quick-Connect design mirrors the OEM connection style with male-to-female fittings, enabling the adapter to install directly between the fuel line and fuel rail. Featured in every fuel pressure adapter fitting is a built-in 1/8-27 NPT port, giving drivers the flexibility to thread in a fuel pressure sender, tie into an existing gauge setup, or route a nitrous feed line.

For added reliability, each inline fuel pressure gauge adapter includes an internally mounted O-ring and retaining clip at the female end. This ensures a secure, leak-free seal that maintains proper fuel system pressure. The 1/2” and 5/16” models are universal for EFI vehicles using those line sizes, while the 3/8” Cummins-specific adapter is engineered to match the factory quick-connect system on late-model heavy-duty Ram trucks.

If you’re upgrading a Fuel Pressure Gauge setup or stepping up your car or truck’s performance, our Quick-Connect EFI Fuel Line Adapters deliver a fast, plug-and-play option for your installation.
