The new gage reads empty at 240Ω, the level sender only goes to 200Ω, thus the gage will never read empty. I would add at least 40Ω to the circuit, for best accuracy when the tank is low.
Add the 40Ω at the back of the gauge, at the fuel sender wire connection. Bill Taylor's drawing shows this wire being white with black stripe.
Regarding closed (locked) topics.
The topics were once set to close automatically based on time. Later I decided that was not something we wanted so I turned-off that feature. Unfortunately a bunch of topics had been closed. There is no way to un-lock topics all at once. They have to be unlocked individually one at a time. There's just too many for me to do that. But I am more than willing to unlock them as requested.
So please, if any of you want to revive a locked topic, just write me a PM and I'll be glad to unlock it for you.
