Faria Instruments

<h3>About Faria Beede Instruments</h3><p>Since 1956, <strong>Faria Beede Instruments</strong> has been crafting precision instrumentation trusted by engineers, boaters, and enthusiasts around the world. Founded in North Stonington, Connecticut, this privately held company began its journey as a tachometer supplier for Ford Motor Company — a heritage that established its reputation for accuracy and durability from day one.</p><p>Over the following decades, Faria Beede grew far beyond its automotive roots. Today the company serves global markets with an extensive lineup of analog and digital engine monitoring instruments designed for marine, automotive, powersports, and industrial applications. With more than 60 years of manufacturing expertise, Faria has earned a place on the dashboards of prestigious OEM manufacturers worldwide.</p><h3>Precision Gauges for Every Application</h3><p>At the heart of the Faria catalog are its industry-leading <a href="/7341-faria-instruments-gauges-202044">gauges</a> — engineered to deliver accurate, real-time readings of engine speed, temperature, fuel level, oil pressure, and more. Whether you're navigating open water or monitoring an engine on the factory floor, Faria gauges are designed to perform reliably in demanding environments. Their <a href="/7341-faria-instruments-gauges-200483">marine and specialty gauges</a> are especially well regarded, featuring rugged housings and sealed faces that stand up to saltwater spray, vibration, and UV exposure.</p><p>For customers outfitting a helm or dashboard from scratch, Faria's <a href="/7341-faria-instruments-gauge-set-1480">gauge sets</a> offer a coordinated solution — multiple instruments matched in style, finish, and illumination so the final installation looks as polished as it performs. These sets simplify the shopping experience while ensuring all gauges share compatible signal ranges and aesthetics.</p><h3>Tachometers, Resistors, and Supporting Hardware</h3><p>Faria's legacy in engine speed measurement is reflected in its dedicated lineup of <a href="/7341-faria-instruments-tachometer-gauge-1488">tachometer gauges</a>, available in configurations suited to gas and diesel engines across a wide variety of applications. Clear, easy-to-read faces and reliable signal processing make these tachometers a go-to choice for both OEM installations and aftermarket upgrades.</p><p>Rounding out the ecosystem, Faria also supplies <a href="/7341-faria-instruments-gauge-resistor-47908">gauge resistors</a> — the critical interface components that ensure accurate communication between sending units and gauge displays. Having the right resistor in the circuit is often the difference between a stable, accurate reading and a gauge that fluctuates or fails entirely. Faria's resistors are matched to their gauge specifications, making them a natural choice when building or servicing a complete instrument panel.</p><h3>Why Choose Faria Beede Instruments?</h3><ul><li><strong>Decades of OEM trust:</strong> Born as a Ford supplier, Faria has expanded to serve marquee manufacturers globally.</li><li><strong>Marine-grade durability:</strong> Many products are engineered specifically for saltwater and harsh outdoor environments.</li><li><strong>Wide compatibility:</strong> Gauges and accessories are available for a broad range of engine types and signal configurations.</li><li><strong>Coordinated styling:</strong> Gauge sets and matching accessories allow for clean, professional-looking installations.</li><li><strong>Vertically integrated expertise:</strong> Over 60 years of in-house instrument manufacturing means quality is built in, not bolted on.</li></ul>

easy, quick and hassle free!

good price easy to find part. will see if quality is good when parts arrive.

Why shop on Ebay, when there is Autoplicity. Cheaper prices than Ebay, Faster shipping and good return policies.

Best price anywhere!

the site is well laid out. some products have very little product discription

great price, wayyyy lower than any other companies, even beat the ebay brands prices for name brand parts. this is my 4th or 5th visit, I've lost count.

Easy shopping experience

fast

shopping was awesome and easy , items showed in stk, but delivery was over 9 days

Ordered a set of 5 steel wheels, distributor messed up and only sent me 4. 5th wheel is taking a good couple weeks to arrive due to the distributor messing up the shipment. Autoplicity did make things right and I can honestly say now I would recommend them.

So far so good

Low prices. Tons of products.

I was told it would ship within 48 hours, when I called they told it was 24 business hours.. I think that they think we are morons... Price of items and chipping was really good.. Hope I get my stuff quickly..

Great
