LMC's fuel sending unit noob Question

[My Big Jimmy]

i got all new autometer gauges hooked up to Painless wireing, i had to get a new oil pressure sending unit, will I also have to use a aftermarket fuel sending?. my gas gauge is way over the full mark.
I have read somwhere here that somtimes the bar holding the float pokes a hole in it and the float fills up. just wondering if my problem could electrical before i take down my tank. i do have an extra float tho. thanks for ur help.

Past full is high resistance (beyond the normal 90 ohms)

My guess is that it's not a sender issue, it's a bad connection issue. Clean up the electrical contacts in the fuel sender wire, or run a fresh wire from the gauge to the sender to confirm.

If that does not solve your problem.

What gauge did you get? Autometer has atleast 7 differnt fuel level gauges with differnt resistance levels. What is the part number? Gm's use 0-90ohm gauges.

Glad you got it fixed. Just remember, the question is only dumb if you NEVER ask it.
