You can scroll through here and see what others have used.
The thing to watch out for is the gen is 24V but 80% of the gages out there are 12V.
Try to find a 24V 80 PSI gage, to make it easier.
Beede makes a lot of Marine gages which are affordable and look close to original, but you also have to buy a little $14 adapter board with a resistor in it to use with your 24V system.
I think your sender is ok. Think you had 240 ohms at 0 Psi. That sounds correct off the top of my head.
240 - 33 ohms if I recall correctly.
If you want to change it, I believe any 80 PSI sender with a 1/8" NPT thread and 240 -33 range will work.
I have used Sierra and Datcon before.

Any brands you recommend? Sender/ gauge combo?
I have used all 3 of the following Datcon gauges. All have worked perfectly for me with the senders that came on my 802a. I bought a second of each for when the Beede gauges fail on my NOS 802a. There are also 24v light kits available from the same vendor.
