Alternative to red-fluid? or https://straight-eight.com/product/k...auge-red-fluid
Your opinion: Use; i.e., 1936 Ford needle gauge & sender. 'adjust' float for your tank accuracy.
'36 gauge installation@ your best behest; i.e., bottom edge of dash. hide it with easy-view access, say, a leather or material flap.

For red fluid appearance in orig gauge= roll up -desired length- a red-in-color paper material?

I've read blogs on this quirky 'red'. Does it work? Not for me. It does for me. It works but ambient temperature matters. Mine dried up. Don't smell it or you'll die. I'm scared of the Jolly Roger; I can't look at it, let alone use it.

Thank you -
