Hey, Fuel-Pumps.Net! Why do your Walbro GSL inline fuel pumps cost a few bucks more than the other guys?

Because we don't treat you like the other guys. They sell you a Walbro GSL-series inline fuel pump with no installation hardware and no mounting kit. What good is that? Then you have to find them locally (good luck with that) or order them separately, pay more for them, and wait for them to arrive. What a ripoff!

With every Walbro Inline Fuel Pump Kit we sell, we include the following:

400-929 Installtion Hardware Kit, Including:

  • Terminal Lock Washers (2)
  • Terminal Nuts (2)
  • Copper Inlet/Outlet Washers (2)
  • Crimp-On Electrical Ring Terminals (2)

400-920 Mounting Kit, Including:

  • Sound insulating Sleeve (1)
  • Inline Fuel Pump Clamps (2)

The basic Walbro inline fuel pump kit from Fuel-Pumps.Net includes everything shown in the picture except the inlet and outlet adapters.
