Fuel sending unit


My fuel gauge on my 1970 Chevelle SS is pegged high. The sending unit ground is good and I'm reading about 6.72vdc at the sending unit. Is there anyway to test the sendng unit before I pull the tank and replace it? Thanks, Tim

Mr. Bowtie

Tim if you unplug the wiring to the sending unit does the guage still peg if so it sounds like you have something grounding your guage check for a pinched wire or fualty guage.
