Description

Fuel pressure you cannot see is fuel pressure you are guessing at.

Setting a regulator, verifying a pump, or chasing a lean condition all start with a number, and this puts it in the line. The Radium Engineering Fuel Pressure Gauge with 6AN Inline Adapter pairs a silicone filled 0-100 psi (0-6.9 Bar) gauge, accurate to +/- 2 percent, with a machined and anodized aluminum inline 6AN adapter that installs at any 6AN connection in the system. The stainless steel case and acrylic lens shrug off the engine bay, and the silicone fill damps the needle so pressure reads steady instead of buzzing. Suitable for all fuels, from pump gas to E85.

What You'll Feel

  • Instant confirmation of base and boosted fuel pressure wherever the adapter sits in the line
  • A rock-steady needle, with the silicone fill absorbing engine vibration
  • Regulator setup and pump diagnostics done with data instead of feel
  • One-part installation at any 6AN connection, including the outlet of a Radium FST-R

Features

  • 0-100 psi (0-6.9 Bar) range with +/- 2% accuracy, suitable for all fuels
  • Silicone filled dial prevents needle vibration for easy reading
  • Stainless steel case with acrylic lens
  • Machined and anodized aluminum inline 6AN adapter included
  • Internal silicone bubble is normal and does not affect operation

The Details

The inline adapter is what separates this from a bare gauge: instead of hunting for a spare port, the adapter splices into an existing 6AN hose run and carries the gauge with it, which makes the feed line near the rail or the surge tank outlet natural homes. Radium notes it drops straight onto the FST-R outlet port for surge tank builds. Two care notes from Radium are worth keeping: over-pressurizing the gauge can permanently misalign the needle calibration, so keep it on circuits within its 100 psi range, and PTFE thread sealant paste should always be used on NPT threads during assembly. The item is not application specific, so verify your line size and routing before purchase.
