Well im new to the site and im from Houston, Tx. My name is Sean but most people know me as SSean.
I have a 98 gmc single cab with a lil 6.0 I swapped in months back. But ive been having a problem with one thing. My gas gauge does not mark at all. Ive tried swapping the stock 350 harness for another one, nothing. and also changed the whole fuel sending unit, nothing as well. If anybody has any info or has had the same problem I would much appreciated some help. A friend of mine told me to ask yall because yall have the most swapped obs's.

I will try to get some pics up of my truck as well
