<h1 id="over-engineering-an-oil-tank-gauge">Over-Engineering an Oil Tank Gauge</h1>
<p>2020-09-09</p>
<p>I almost went down the path of investing a huge amount of time and effort into fixing a stuck oil fuel tank float-gauge in my house. Recently, the float mechanism became stuck and permanently displayed <code>empty</code> regardless of how much fuel was in the tank - not ideal. It&#8217;s a 20 year-old tank, so I wasn&#8217;t surprised that the float finally gave out. </p>
<p>Being the wannabe tinkerer that I am, a light bulb went off in my head and I started thinking on how to incorporate some ultrasonic system to display the accurate fuel reading digitally. Obviously my first thought was just to replace the float gauge with a new one and be done with it. That didn&#8217;t sound very <em>fun</em> though.</p>
<p>I briefly looked at other similar projects and started brainstorming the best way I would implement this for my own situation. The best option I came across seemed to be this: <a href="https://scottiestech.info/2017/10/24/diy-ultrasonic-fuel-gauge-level-sensor/">DIY Ultrasonic Fuel Gauge &#47; Level Sensor</a></p>
<p>An ultrasonic system with a cool mini display sounded pretty rad - much cooler than just replacing the broken gauge with a new float arm. So it was settled.</p>
<h2 id="my-oil-think-tank">My oil think-tank</h2>
<p>I quickly thought through my options in my head before jumping too far into things (and even included a &#8220;poor-mans&#8221; temperature strip option):</p>
<table>
<thead>
<tr>
<th>Solution</th>
<th>Cost</th>
<th>Time</th>
</tr>
</thead>
<tbody>
<tr>
<td>Ultrasonic Gauge</td>
<td>$40-50</td>
<td>~2-3 hours</td>

<tr>
<td>New Float Gauge</td>
<td>$25-30</td>
<td>~45 minutes</td>
</tr>
<tr>
<td>Temperature Strips</td>
<td>$10</td>
<td>~2 minutes</td>
</tr>
</tbody>
</table>
<p>My mind was still set on building and implementing the ultrasonic option. It would be a great learning experience at the very least!</p>
<p>So, before I ordered any parts or started designing a case that would house this new super-cool device, I went to investigate&#47;remove the float gauge to get a better look at the damage. With the help of some penetrating oil (the original installer went crazy with the pipe dope) and my trusty wrench, I opened up the gauge cap, partly lifting the float from the tank. Right away I noticed that the float and shaft were slightly stuck together in one small area. I poked it with my finger.</p>
<p><em>The float set itself back into the correct position. It was fixed.</em></p>
<p>How could I have been so dumb. I was so excited about <em>building something</em> that I jumped into implementation before fully realizing the problem. Talk about a metaphor for web dev, am I right?</p>
<h2 id="overthinking-simple-problems">Overthinking simple problems</h2>
<p>I can&#8217;t speak for all designers &#47; developers out there, but I catch myself (far more often than I&#8217;d like to admit) over-engineering a solution because of some perceived notion that it is the &#8220;best&#8221; option. Most of the time it isn&#8217;t actually better, it just seems more <em>fun</em>.</p>
<p>Now don&#8217;t get me wrong, fun is a good thing most of the time. It&#8217;s just that some instances call for the quickest, cleanest, easiest solution in the name of efficiency - just be sure to have fully explored the problem <em>first</em>.</p>
<h2 id="final-decision">Final decision</h2>
<p>So I ended up doing nothing. I simply re-threaded the cap and placed the float back inside the tank. I know I saved myself time and money, but I can&#8217;t help but feel like I failed&#8230;</p>
<p>Just like in the world of software, it&#8217;s best to avoid over-engineering simple problems.</p>
