Product Details

The Holley 12-821 Gerotor Replacement Kit is an essential maintenance component designed to restore optimal performance to your Holley electric fuel pump. This complete replacement kit is specifically engineered for use with Holley fuel pump models 12-125 and 12-150.

Complete Kit Includes:

  • Gerotor set - the critical pumping element that moves fuel through the system
  • Lower gasket - ensures proper sealing at the pump base
  • Wear plate - protects internal components from friction damage
  • Wear plate O-ring - provides reliable seal around the wear plate

The gerotor is the heart of your electric fuel pump, using precisely machined inner and outer rotors to create positive displacement and consistent fuel flow. Over time, wear on these components can reduce pump efficiency and fuel pressure. This genuine Holley replacement kit restores your pump to factory specifications, ensuring reliable fuel delivery for demanding performance applications.

Regular maintenance with quality replacement parts like this kit extends the service life of your fuel pump and helps maintain consistent fuel system performance.

Very easy and quick ordering process

Purchased my mishimoto heat tape. Cheapest price around and the shipment was delivered in a very reasonable time. Couldnt be happier

Price was lower and the website was great.

Very fast shipping, always great prices.

shipped fast, cant wait to put it on the jeep, would buy from here in the future.

I'll admit to being skeptical at first, but the price was worth the risk. Turned out to be one of the best online transactions I've experienced. Received item 3 days after purchaseing and the best price I found. And I looked hard! A+

Rather amazing and uneventful service in this day and age. Ordered a Thule bike rack for my Nissan Murano. It was in stock (unusual for high-end specialty products), shipped the next day, and was on my doorstep in a few days (excellent for a 60 lb. large box). I'd buy anything from these people without any reservation. AND, your order is insured - completely superfluous. Oh, and did I mention, the lowest price I could find ANYWHERE, and not by a few dollars - a lot.
