This adapter sleeve and clamp simplifies the installation of an Aeromotive or Walbro fuel pump into the factory fuel pump housing and carrier.
Included is an all stainless steel mil-spec hose clamp to secure the fuel pump. There is a ledge on the bottom of the fuel pump sleeve which stops the pump from sliding too far down, but the clamp is to keep the pump secure.
Optional, is an angled fuel pump filter sock (fuel pump strainer). The fuel pump filter is made to fit the large center inlet fuel pumps. Normally, the fuel pumps with large center inlet have the "340" number associated with them.
