Ok.... got in the instrument cluster that I got off Ebay for $14. My fuel gauge was floating/buzzing/ and pointing towards the oil pressure gauge. I put this cluster in and the fuel gauge read correctly.
So.... I went to step 2....disassembled both clusters replaced my fuel gauge meter with the meter from the cluster I just received. Buttoned everything back up, and all looks good, especially since the refurb'd cluster had a new clear face lens that I transferred also.
Only thing I noticed is w/the new fuel gauge meter in, the needle doesn't swing all the way past full then settle in to position like my old one. It just slowly goes to the correct fuel level reading. I looked @ the meters in the reconditioned cluster, and the meters look fairly new, and OEM. No numbers I could grab that would help others unfortunately.
I'll be keeping an eye on it, but so far....no complaints.
