I guess my tank sending unit is shot as it sometimes reads fuel and sometimes does not. Yes, I checked the grounds and yes, I belive the gauge itself is ok. I already looked @ RA, Summit, Fleabay and a couple other sites, no luck so far. Summit even stated they don´t stock it. Any idea where to look or what other model used the same part? 1967 Lesabre 400 Custom Convertible w/340 cui AT BTW: Need one for my 72 Olds 98 w/455 cui AT as well.
