24 | ASP October 2017 Technical with moisture in the fuel. If the fuel tank is steel, there's usually corrosion on the "roof " of the tank. is is why a new pump comes with a new intake strainer, and it's also why the fuel tank should be completely cleaned out when installing a new pump. e number one reason that replacement fuel pumps fail is failure to clean out the fuel tank. When installing a new fuel pump, safety and cleanliness are critical. If the fuel tank must be removed to access the fuel pump module, sometimes it's tempting to lower the tank only as far a necessary rather than removing it completely. is is a mistake because it increases the risk of stirring up sediment inside the tank that will damage the new fuel pump. Any time a new fuel pump is installed, the tank should be removed, drained and cleaned. After a fuel pump module is installed, the fuel system must be primed by cycling the ignition switch on and off several times. Often you can hear the pump change pitch as it finally begins making pressure. In some fuel tanks, the module's reservoir does not automatically fill with fuel even when it's submerged, and fuel must be poured into it manually during or after installation. Some- times this requires filling the tank. e information presented here is just the basics. e Fuel Pump Manufacturers Council, part of the Automotive Aftermarket Suppliers Association, has produced a series of videos that provide more information than we could ever fit into a magazine article. If you've suffered a lot of fuel pump comebacks, or even if you just want to learn more, search the web for these free training videos. ■ After 27 years of writing for automotive trade journals, I am retiring from the pub- lishing business. To say it's been a dream job would be an understatement. The places I've been, the cars I've driven, the things I've seen and done and learned are more than most people experience in a lifetime. Of course it's been made even richer by all the won- derful people I've met and worked with over the years. One of them was my first editor at Chilton Book Co. He told me that by the time a guy looks up the service procedure he needs, he's probably already in trouble, so it's my job to help him. That's what I've tried to do in every article I've ever written, and readers of every publication I've worked on have told me that I've succeeded. High praise indeed: it's been an honor to serve you. While I am leaving the publishing industry, there is still some wrench-turnin' in my life, so I'll still be checking in with iATN frequently. Maybe I'll see you there. — Jacques Gordon Even plastic tanks can have corrosion from metal parts of the fuel pump assembly.
