Steve,

Go ahead and remove it. it is not needed.

It is still needed. It is actually a bit of a misnomer that it is a 
voltage regulator. As the fuel and temp senders change resistance their 
current requirements change. The gages also have different current 
requirements at different temperatures, which the instrument regulator 
takes care of., so you need to replace the dash regulator.

Yes, the fuel gauge will also be affected.

You might try removing the intermittent instrument regulator and 
removing the metal cover from it. You will find a pair of contacts in 
there that you can clean with some emery paper. Be careful to not bend 
anything. My instrument regulator developed an intermittent connection 
where one of the rivets go through the phenolic and attach to the wire 
connectors. I was able to clean mine up and solder  them to get the 
regulator to work until I was able to order a replacement from the 
dealer.s I recall the replacement cost about $20.

Peace,
Pat
