504 Fuel Gauge

[Bruce Llewellyn]

7.5 volts sounds right - these gauges are a bridge type electrically. The sender can be put in facing one of three ways, however. If it is in the correct position it should be pretty accurate. If it's in one of the other positions it either jams on the slosh baffle (never reads more than 1/3 of a tank) or the last quarter tank is only good for about 15 km if it's in the other wrong position. The trouble is, I can't remember which way around is which...

Yes that’s right the terminal faces the Left hand side of the car.

Early and late are the same. 505 are different they have a clip, but you can put a 505 steel tank in a 504. And other way round.

Isn't the 505 tank around 70 Litres ?

Early 505 tanks were 56 litres (same as 504), later ones from about 1984 on when the SR variant was introduced, were 70 litres.

I was under the impression that the GL has 60 L tank while the GR/SR have 56 Litres

What I quoted was for Australian models. Perhaps Egyptian spec cars were different.
