We just finished putting a Northstar in a '48 Cadillac. Drilled a hole in tank near sender-opening--where we could tighten jamb nut from inside tank--used a fitting from Lowe's for a tank: water? air? I dunno, just looked like what we needed. Ran a fuel hose from fitting up high into wheel well, & fastened a plastic, see-thru filter(about 2" in diam.) into end of hose & secured to inner fender. Filter must've been for a big truck/tractor, going by size of opening. Try to run a 1/2-inch fitting/hose, at least. Really think ours was bigger than 1/2!
