This pump solved my difficult starting problem. I have a new 21hp Briggs and Stratton Vanguard engine. in my 1982 Cub Cadet which was taking too long to start, especially in cold winter weather. The problem is that the engine uses a vacuum fuel pump, and the colder the weather, the harder it is to create a vacuum when starting the engine. I installed an Airtex E8016S electric fuel pump that comes with a filter that threads into the inlet end of the pump (silver color - clear zinc plated). It starts with the key, wait a few seconds, turn the key to start and after 5 seconds on a 20 degree winter day the engine comes alive. It used to be that my machine would not work without battery overload. A pump filter can be purchased from Weaver's Auto Parts or Oreilly Auto Parts for about $8, part number G17. I also have a Mr. Gasket 9710 after the pump to keep my carburetor from over-gasing. I left the original fuel pump on the tractor and all my modifications were before that and all the lines are 1/4" fuel lines so I had to buy some 1/8" NPT brass fittings from NAPA Auto.
