[Roadsters] Running on E in California

[twokeelya at gmail.com]

Hello fellow roadster peeps. I posted before, let the roadster sit for
years in my garage, pulled her out, had the tank boiled and coated, put
back in but the fuel gauge read 1/2 full all the time. I removed the
sending unit and put it back in, now the needle only moves up to "E" even
when full. I'm stumped, is there a fuse or regulator that controls the
gauge?

Thanks in advance
Richard
