Re: fuel gauge

["Alex Ting" <alext@nu2u.net>]

Dick,

so you are saying that 220ohms empty and 47 ohms full?
The reason I'm asking here is that I am going to put a full
custom gauge panel in the corrado dash, and I am looking
for the correct fuel gauge without having to change senders.
The closest thing I show so far for VDO is 240-33ohm empty
to full.
Do you think this discrepency would throw the reading way off?

thanks for any and all help!
