The new tachometer has the same dimensions as the original except for the RPM's, 4000 vs 3000. Other than that it was a simple install and a minor adjustment to dial in the rpm's. ### ⭐⭐⭐⭐⭐ Just right *by A***T on February 20, 2023* He liked it so much he ordered more ## Frequently Bought Together - Murphy by Enovation Controls ATH-40-A Analog Tachometer/Hourmeter, 12/24 VDC (20700254) - Murphy by Enovation Controls 20T-250-4-1/2 Temperature Swichgage (10702042) - Murphy by Enovation Controls AT-30 12/24 VDC Analog Tachometer (20700245) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/195660939-ath-40-a-analog-tachometer-hourmeter-12-24-vdc-20700254](https://www.desertcart.vu/products/195660939-ath-40-a-analog-tachometer-hourmeter-12-24-vdc-20700254) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
