Rallye dash gauge upgrade

In reference to the RTE webpages.. Bend the little thingy does not work !
I just received yet another rally fuel gauge from a member here that had a external regulator added on in similar manner. Needless to say the other vendors regulator had failed, Because it was in a corrupt circuit. In this condition any solid state regulator would totally fail eventually. They all have built in protection that causes them to cycle off and on again in a corrupt circuit condition. That protection can cycle only X number of times though.
Why in the heck someone with "engineering" in their title hasn't figured this out by now is beyond me. I've been guiding owners out of this chit for more than 7 years now.
The OEM gauges can work well. The hash marks on their screens can be identified to a point. They are only range indicators though so spot on accuracy is not possible.
If you want to read 202.4 degrees water temp, 47.8 p.s.i. oil pressure, 3 gallons to empty, only modern technology will get you there.
Good luck with whatever route you take.
