Porky is right. When I did mine, I got a 1/4 NPT tee from Home Depot and Autometer kit 3234 which had the braided hose and fittings needed to relocate the stock sender and the aftermarket sender. I think I had to buy a couple 1/4 to 1/8 NPT reducers, but its been a while, I think I only needed one reducer outside of what was included in the Autometer kit.
