Mike, sorry I couldn't make it down to Tablerock Lake the 17th and 18th to meet you. Randy sent me some pics of the three STVs and they look great!
Earlier this year I installed one of the Gaffrig sending units in my Euro that Anthony was telling you about. It will bolt right in (you will have to get some longer bolts because of the thicker body). The only other thing you have to do is run 12v pos to the sender (that will make three wires total to the sender). There are two small screws on the sender to set the "full" and "empty" marks on your gauge.
I didn't get any instructions with mine but found them at www.livorsi.com. I'm very happy with this setup but it does not quite get rid of all the bounce. I would say it's around 80% better though. If you have any questions feel free to contact me.
