Will S/W gauges work with stock sending units?

This crap annoys me.
100% agree.

the further annoyance is amplified when you wind up having to use like three adapters to make the damn thing work. which just cheezes me to no end. it looks bobo, that's just more potential points of failure, and in my particular case there was just no room to operate in the space (383 in a truck with AC/heater lines running).

thanks to my hoarding tendencies i was able to find a single adapter and make the temp sensor work, but still that was all way too much for something should be a no brainer.

and not to get down on tank inc, but they will sell you every single little doo-dad and farkle you need... so why not just explicitly say: hey dum-dum, i see you're buying a fuel level sender so just go ahead and buy our gauge and save yourself the hassle because it won't really work with anything else on the market that doesn't look cheeze dick.
