I posted this link once before.

The sender is the same, so if you have a good one from an EFI car, it will swap over.

I thought I also ready other candidates for a replacement sender were Mazda's of the same vintage, 323?

Mazda RX-7. The 1991 FSM lists 7 ohm when full, 32.5 ohm at half, and 95 ohm when full.

Mazda RX-7. The 1991 Factory Shop Manual lists
Sender Resistance: 3ohm Full, 32.5ohm Half, 110ohm Empty
Gauge Resistance: 7ohm Full, 32.5ohm Half, 95ohm Empty

An Australian site shows a Mazda 323 goes from 7-95

These are the same as our Festivas.

So a 91 rx7 sending unit works? Does any 2nd gen rx7 work? Plug and play?
