This simple adapter makes the installation of a Walbro or Aeromotive fuel pump into the factory sending unit safe, secure and completely functional. The pump rests on a ledge at the bottom of the sleeve and is held tightly in the bracket by a mil-spec stainless steel clamp. A well thought, quality built solution to a common retrofit problem.

This kit includes:

  • Anodized fuel pump sleeve
  • Stainless steel mil-spec hose clamp
