72 Blazer 4WD fuel gauge problem
I'm new to posting and trying to get involved in some of the great discussions on this really fine website. So please ignore my ignorance......I'll figure it out!
I posed this thread in the 72 Pickup forum and couldn't figure out how to move it here. I've been reading many threads on fixing my gauge, but haven't been able to figure this one out. My gauge only registers empty to 1/4 full. My new sender reads 0 ohms empty and close to 90 in the full position. I followed the tan wire to the fuse box, finding no problems there. I disconnected that wire at the fuse box and the gauge goes just past full to about 1-2:00. Not to the 3:00 position forums said it should go to. When I ground the fuse box terminal, the gauge goes to MT. With the sender in the MT position, it reads correctly. When I raise the float to the full position, it won't go past 1/4 full. Any help will be greatly appreciated.
