Product Details

The Fuelab 84821-1 is a standard-length, 848 Series inline fuel filter featuring a 75-micron stainless steel mesh element and an integrated check valve — all in a single, compact billet aluminum housing. By combining filtration and check valve functionality into one unit, this filter helps maintain fuel system pressure after engine and pump shutdown, while eliminating the need for separate components and additional 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 mesh element — cleanable and reusable for long service life
  • Standard-length 3-inch filter element for solid filtration capacity
  • Billet aluminum housing with military-spec anodized finish (MIL-A-8625, Type II) for corrosion resistance and durability
  • Machined internal radii for minimal pressure drop and maximum flow efficiency
  • Supports up to 200 GPH flow capacity with a 200 PSIG maximum pressure rating
  • Male AN flared fitting end caps for direct connection to fuel system components
  • 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 design protects the check valve assembly behind the filter element, shielding it from contaminants and simplifying installation. This inline fuel filter is an ideal solution for high-performance fuel systems that demand reliable pressure retention and clean fuel delivery.

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.

fast and easy to find the parts I need thank you

Great price and fast shipping. Good experience!

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

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.

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