Key Features:

  • Designed for Ford 9-inch rear differentials with 31 spline axles
  • Aggressive design with 4 preload springs for enhanced grip
  • Nodular iron case construction for superior strength and durability

  • Fully rebuildable design for extended product lifecycle
  • Backed by Yukon's one-year warranty against manufacturing defects

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

I like the "pay with amazon" quick link

Good price for great name brand car parts. AEM fuel filter very low price and new. Hope the shipping is as great as the price. :)

Amazing prices

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>
