Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

Anyone that has approached the subject of substituting a higher volume fuel pump knows that fitting said pump into a stock housing can be a hassle. What's more is that certain methods can lead to less than safe or reliable results. Enter the Rally Road fuel pump adapter sleeve. 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. 

Fits Walbro 450lph high volume fuel pumps.

This kit includes:

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

This part fits the following BMWs
1992-1999 E36 323i 325i 325is 328i 328is
