fuel issue

in my 64 i have the behind seat tank still. po put in 72 dash, meaning a 90 ohm gauge. as you know my tank sending unit is 30ohm. does anyone make a 90ohm in the cab mounted tank sending unit? im tired of topping off every time i drive to make sure i dont run out if gas

This might work : GM Fuel sending unit conversion 30 ohm

thanks but thats the opposite of what im looking for. ive found several things on if you have a 90 sending unit making it work on a 30 gauge. i have the exact opposite problem. i need a 90 sending unit that will fit behind the seat of my 64, so it will match my 90 fuel gauge from a 72

I've fiddled with fuel gauges a pretty fair amount. With your situation, the only solution I see is grafting a later model sending unit onto your sending unit--all mechanical, instead of electrical from here out.

im beginning to think my easiest option is to just get an autometer 30ohm fuel gauge. just really wanted to keep the old guages

Jeremy, mating 2 sending units may be simpler than you first think. You essentially cut 2 pipes and join 2 pipes using flex fuel hose & 2 clamps. (I'd use fuel-injection hose.) You'll prolly need 2 inches of it!

And, if you're lucky, maybe the '67 send unit is a simple bolt-in. Look at both at a parts house & compare?

Maybe this can work, Adjustable 6-24" Fuel Tank Sender 0-90 Ohm
