When you buy a Bypass pump you only have 2 leads off the bottom of the pumps. So I say turn the Demand pump into a Bypass Pump style pump. Yes, it is using a external PS but it is a Bypass style pump. After you do this you can just by a bypass pump.
Them Micro switch are very touchy if your on and off the gun. Relay’s aren’t made for this type of work. This is where a solenoid is better to use in this case. My video’s I will be posting will show you and make you understand better.
Video drops today!
I’m showing you how to save every demand pump the right way.
I like the dwell pressure switch (PS) because you can grab a replacement at almost any store—even on the weekend. Plus, you can safely throw more amps at it without issues.
I don’t recommend the digital switches. If something goes wrong, some of them max out at 150 PSI. When they reset, they can spike pressure and blow your lines unless you’re running top-grade hoses.
Alway’s stick with what’s reliable, field-ready, and serviceable anywhere.
