The \u003cstrong\u003eRadium Engineering 0-100psi Fuel Pressure Gauge\u003c\/strong\u003e reads 0 to 100 psi (0 to 6.9 BAR) with +\/- 2% accuracy, in a rugged stainless steel case with a silicone-filled dial that keeps the needle steady while the engine runs. Choose it bare with its 1\/8\" NPT fitting, or bundled with a straight or 90-degree 8AN ORB adapter to thread directly into Radium rails and regulators. A simple tool that answers the question every tuner asks first.\u003c\/p\u003e\n\u003ch3\u003eWhat You'll Feel\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eA rock-steady needle you can actually read with the engine running, thanks to the silicone fill\u003c\/li\u003e\n\u003cli\u003eConfidence dialing in base pressure instead of trusting a spec sheet\u003c\/li\u003e\n\u003cli\u003eFaster diagnosis when something feels off, since rail pressure is right in front of you\u003c\/li\u003e\n\u003cli\u003eA clean, direct install on Radium components when you pick an ORB adapter option\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e0-100 psi (0-6.9 BAR) range with +\/- 2% accuracy, suitable for all fueling applications\u003c\/li\u003e\n\u003cli\u003eSilicone-filled dial dampens needle vibration for easy reading (a small internal bubble is normal)\u003c\/li\u003e\n\u003cli\u003eAcrylic lens over a stainless steel 1-5\/8\" OD case with 1-3\/4\" OD bezel, black bezel and housing\u003c\/li\u003e\n\u003cli\u003eNickel plated male 1\/8\" NPT fitting\u003c\/li\u003e\n\u003cli\u003eOptional straight 8AN ORB adapter (20-0075) or 90-degree 8AN ORB adapter (20-0386) variants\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eThe Details\u003c\/h3\u003e\n\u003cp\u003eThe gauge itself carries a male 1\/8\" NPT thread, which fits the gauge ports machined into most aftermarket regulators, rails, and damper kits. Always use PTFE-based thread sealant paste on the NPT threads, thread it in gently by hand, then finish with a wrench 1.5 to 3 turns past hand tight. Do not muscle the gauge in by twisting the housing itself, since that can damage it. The two adapter variants matter if you are mounting to a Radium fuel rail or regulator with an 8AN ORB port: the straight adapter stands the gauge off the port, while the 90-degree version turns the face where you can see it in a crowded engine bay. One caution worth knowing before you plumb it in: overpressurizing the gauge can permanently misalign the needle calibration, so keep it on systems within its 100 psi range.\u003c\/p\u003e\n\u003ch3\u003eKit Includes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e1x 0-100psi fuel pressure gauge with male 1\/8\" NPT fitting\u003c\/li\u003e\n\u003cli\u003eAdapter per selected variant: none (20-0029), straight 8AN ORB adapter (20-0075), or 90-degree 8AN ORB adapter (20-0386)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eUniversal: any fuel system gauge port with a female 1\/8\" NPT thread\u003c\/li\u003e\n\u003cli\u003eRadium fuel rails, regulators, and components with 8AN ORB ports (adapter variants)\u003c\/li\u003e\n\u003cli\u003eGasoline and other fueling applications within a 0-100 psi range\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Radium Engineering","offers":[{"title":"No Adapter Included","offer_id":43672688132163,"sku":"20-0029","price":47.45,"currency_code":"USD","in_stock":true},{"title":"Include 8AN ORB Adapter","offer_id":43672688164931,"sku":"20-0075","price":61.7,"currency_code":"USD","in_stock":true},{"title":"Include 90 Degree 8AN ORB Adapter","offer_id":43672688197699,"sku":"20-0386","price":75.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0064\/7754\/5539\/files\/radium-engineering-rad-20-0029-no-adapter-included-28366354022470_8b89daa8-996a-4117-b4cd-e23a47e92004.jpg?v=1786717045","url":"https:\/\/www.tunedbyshawn.com\/products\/radium-0-100psi-fuel-pressure-gauge","provider":"Tuned by Shawn","version":"1.0","type":"link"}
