What is the purpose of the shunt resistor? I could certainly understand a shunt capacitor to remove any stray AC. I can easily order a 750Ω resistor. I have a wonderful case of tennis elbow on my right arm at the moment and was not looking forward to removing all those screws on the boot liner. However, I have now treated myself to a Milwaukee 1/4" cordless ratchet and a set of 1/4" square drive screwdriver bits (I already have a large set of 1/4" sockets, metric and AF), so it will now be very easy. I also have to take the pedal box cover off as well, to replace the worn out friction coating on the clutch pedal with glued on emery cloth, where the Milwaukee will be perfect.

Simply to lower the resistance measured by the display circuitry. In this case it changes the range to give more sensitivity at lower fuel levels which is where you need it. Downside was that gauge indicated 100% for first 20-30 miles from full tank.
Remember this mod was in conjunction with the longer sender though.
