Kombi fuel guage
pavelmac - June 18th, 2003 at 10:13 AM

Hi,

Can anyone tell me if the fuel gauge from a '76 T2 is compatible with my '71/'72 T2? Only I have just swapped my old dash (in MPH) for a '76 one (in KPH) and all is fine but for the fuel gauge needle disappearing off past full! I've tried to swap back to the original dash but I get the same result. So I don't know whether to conclude that I have got the wrong wires or I've buggered up the sender.
The dash differs mainly by the '76 version having a silver box that appears to connect to the fuel sender & and a few less bulbs (only 1 indicator bulb & no low beam bulb).

Any ideas?

Maybe you need to use the matching sender? :o

My kombi's both had the opposite problem: even when full to overflowing, they still only registered between 1/2 and 3/4 of a tank. At least I've never ran out of petrol though, I always have at least 1/4 of a tank as reserve!!! :thumb

Does sound like something incorrectly wired if putting the old gauge gives the same incorrect result.
I'm planning to do the opposite in the near future, (swap new dash for old) so I will keep you posted. (Don't hold your breath though).

I have a new 73-80 sender in my hands as I write. If you look on the back of the fuel guage, they use a different gizmo to 'damp' the circuit- or so im told. If you use same year sender/guage it should work. Check the earth lead for the tank. On my '75 in screws to the top bulkhead above the tank and in my case was not earthing- more like mooning ;)

Wire the sender directly to the guage and see if it all works without the kombi wiring being involved. If it all works then, wires are shot.

A big shout out to Andy in thanks for the piccy before I went a drilling.:beer your way fella

on the back of the instrument panel is a little rectangular box with a couple of terminals of which one wire goes to the fuel gauge (simplifing it a bit) it stabilises the voltage at about 8volts or thereabouts so that the guage gives a staedy reading no matter what output is coming from the alternator or battery.
because both the panels are now reading full, it seems like you have bypassed the voltage stabiliser & hitting the gauge with the full 12 to 14 volts

Any time Toddly,
Just hope you didn't drill into the tank :D:D:D
