Temperature Sensors x 4 - Is it possible?

[Smollers]

Hello all, my first post and a novice at this so please don't shoot me down too hard!

We have a 1999 Impreza running the G4+ plug in ECU. We have coolant temp on AN Temp 1 and IAT on AN Temp 2 (on the expansion loom). I've bought 2 x Bosch PST-F 1 sensors so we can monitor oil and fuel pressure/temps + build in some safety. We can connect the oil temp to AN Temp 3, but how can we connect fuel temp? Is there another input we can use and configure for this?

Thanking you all in advance, Andy.

You can use an AN Volt input if you fit an external pull-up resistor.
