You do not need to change your IVR when running a meter match. It has an internal regulator to power the fuel gauge. They say its only rated to run one gauge so you would need to use your existing IVR to power the temp gauge. So some modifications will be required to isolate the two.
You can buy those "calibration box"....its called a resistance decade box. https://www.amazon.com/dp/B00023RTZO/?tag=fabo03-20
Where do You get the calibration items --- "cal box" ? -- "meter match" ? --- Thanks
-- I have a aftermarket tank, and sender, in My 64 Falcon. -- My gage is a Summit unit, mounted under the dash, with temp & oil pressure gages, and I was told that The IVR was built into the gage. When the tank is full, the gage reads full, but it drops, quite, quick to an empty reading, and the 16 gallon tank still has aprox. 5 - 6 gallons in it. This is OK, in that I should not run out of gas, but I 'd rather that the gage be accurate. -- Do You think that the Meter Match device will work with this set up ?-- Instrument Voltage Regulator. I takes the 12 volt battery power and reduces it to 5-6 volts for the gauges. --
Although blocked it may yet serve a good purpose down the road!
There's that modern Hemi rearing its head again, lol.
Has anyone tried a knotted string with a weight dropped down the filler tube?
I replaced with the available Spectra unit. It was not the issue IMO. looks totally incorrect but was not the real issue! Went from 5/16 to 3/8, it read correctly with the meter. The gauge was the issue! Upgrade your gauges JMO! If you think the 50 year old gauge is going to read anything correctly you are wishing!

This idea doesn’t really make much sense. The IVR is located IN the fuel gauge. It would be difficult and pointless to try and isolate it. Why would you completely disassemble the dash and go to the work of isolating a 50 year old mechanical regulator that is known to fail?
Makes much more sense to replace the ivr. The meter match with the built in regulator is a cool thing, but likely designed for when you are not using the other stock gauges.
-- Never used a Meter Match. -- Summit Tech says that the gage has a resistor built in.Not all of them have the voltage regulator built into the fuel gauge. In fact, most of them do not. Meter match is running a standard 7805 regulator and wont power more than one gauge. So, you need another regulator if you want to use the oem temp gauge.
Have you even installed a meter match before? What I said is not "difficult and pointless", in order to use the meter match it runs off its own regulator.
I dont use 50 year old regulators, I install my own additional 7805 on a heatsink along with the meter match. Much safer than risking the bi-metal type and having the contacts stick closed and frying the gauges. Although in 30 years of owning mopars I have only had them go open, I know its a possibility for them to hang closed. --
-- Sorry -- You were talking to Mike69cuda-- What???

Ah ok, they do make the meter match for brand X that does not have the regulator.
