Product Details

The Fuelab 84821-3 is a standard-length, in-line fuel filter from the 848 Series, featuring an integrated check valve and a 75-micron stainless steel element. By combining the filter and check valve into a single billet aluminum housing, this unit helps maintain fuel system pressure after engine and pump shutdown — eliminating the need for separate components and extra fittings.

Key Features:

  • Integrated check valve maintains fuel pressure after engine and pump shutdown, helping prevent vapor buildup in fuel rails during engine cooling
  • 75-micron stainless steel filter element — cleanable and reusable for long service life
  • Standard length (3-inch element) for a compact, space-saving installation
  • Billet aluminum housing with military-grade anodized finish (MIL-A-8625, Type II)
  • Male AN flared fitting end caps for direct connection to fuel system components
  • Supports up to 200 GPH flow capacity with a 200 PSIG maximum pressure rating
  • Compatible with gasoline, diesel, methanol, and ethanol fuels
  • Includes a low-profile saddle clamp mounting bracket
  • Backed by a 2-year limited warranty

The 848 Series integrates filtration and check valve functionality in one streamlined assembly, protecting the check valve from contamination while reducing complexity in performance and racing fuel systems.

Faster shipping than I expected. Easy order process. The ignition switch was my problem and Autoplicity part was exactly what I needed at a price better than anyone else had, with shipping included. I will definitely look to them again when I need any more parts for my Monte Carlo SS.<br>Only slight negative would be it took a few days to get an email with tracking number so I would know when my part would come. But once I got it, found it was coming sooner than I originally thought, which was great.

Great price and fast shipping. Good experience!

Very fast shipping, the product should arrive today acording to UPS, and I order it 2 days ago. The customer service is also great.<br><br>Thanks again,

The shipping was fast and the customer service was great. I accidentally hit submit twice, and they promptly cancelled my accidental order. If you have any problems, just call!

Very fast shipping and bottom line prices for every part. Awesome website. Will be telling all my friends about and using again for sure!!

So I have an old car. It's and 83, seven years older than me. I'm also a student so I don't have much money and need to make as many repairs myself to save money. I go out to the local pep boys and auto zone to to try to find a repair manual that is for my old model but it's not available. I check online and there are very few copies on line. Autoplicity had the right manual at the lowest price by a good margin. <br><br>TLDR; Autoplicity has EVERYTHING and at a cheaper price

Very quick service and lowest price.

Prompt order processing and shipping, the item I received came in good condition and I am eager to get it installed on my car. Over the phone customer support was prompt and polite, I would order from them again.

awesome price and super fast shipping. I will use again. Thanks

The magnaflow kit that I ordered was about $100 cheaper than any other site I could find. Shipping was fast, and relatively cheap too.
