however, it's for 94 LS. the circuit board shown can be different than 91.

lexls?? any help here? i have a 92 w/ a fluctuating gas guage and all info on caps seems to be for 93-94...

which caps do we replace, please?

Ok, I found my notes on this. I **think** C12 (25v 47uf) is the main cap for the fuel gauge on 90-92 clusters. C16 (10v 100uf) also may have something to do with the fuel gauge. This is just from testing the caps I pulled to see if they were out of spec and C12 was the furthest from spec. I replaced all the caps on my boards so I can't say for sure. Let me know if these are truely the ticket!
