THIS IS FOR A NEW 1958 1959 1960 CHEVROLET IMPALA BEL AIR & BISCAYNE FUEL SENDING UNIT WITH A 3/8 FUEL LINE. THIS WILL NOT FIT A STATION WAGON. THE 3/8 LINE WAS USED ON ALL SMALL BLOCKS WITH 4 BARREL CARBS AND ALL 348 ENGINES. THESE SENDERS COME WITH THE FILTER AND GASKET. THIS IS A TESTED UNIT. WE HAVE HAD WAY TOO MUCH TROUBLE WITH CHEAP SENDING UNITS NOT WORKING RIGHT OUT THE BOX, DEFECTIVE FLARE FITTINGS AND LOOSE FILTERS. NOBODY WANTS TO CHANGE THIS SMELLY AND MESSY PART TWICE. WE DON'T EVEN CARRY THE CHEAP ONES ANYMORE. SO WE NOW GET OUR SENDING UNITS FROM A DIFFERENT SOURCE THEN WHAT EVERYBODY ELSE SELLS ON EBAY AND THEY COST A LITTLE MORE MONEY. WE TEST OURS BEFORE WE SHIP WITH AN OHM GAUGE AND WRITE THE ACTUAL EMPTY AND FULL OHM READING ON THE BOX. WE KNOW IT WORKS AND YOU KNOW IT WORKS BEFORE YOU PUT IT IN. SKU# 20605
