Product Details

The Fuelab 85831-2 is a long-length, 858 Series in-line fuel filter featuring a 6 micron fiberglass filter element and an integrated check valve — delivering two critical fuel system functions in a single, compact unit.

The built-in check valve maintains fuel pressure in the system after the engine and fuel pump shut down, helping to preserve fuel prime and support consistent restarts. Because the check valve is housed inside the filter body, it is protected from contamination and debris by the filter element itself, extending the life of both components.

Key Features:

  • 6 Micron Fiberglass Element — provides fine filtration to protect fuel system components from harmful particulates
  • Integrated Check Valve — maintains fuel pressure after engine and pump shutdown; eliminates the need for a separate check valve and additional fittings
  • Long Length / 5-Inch Element — increased filter media surface area for greater flow capacity and longer service intervals
  • Universal Fuel Compatibility — check valve and filter materials are fully compatible with gasoline, diesel, ethanol (E85), and methanol fuels
  • Simplified Installation — all-in-one design reduces plumbing complexity and the need for extra adapters or fittings

The Fuelab 858 Series is purpose-built for performance and race fuel systems where consistent fuel delivery and system pressure retention are essential. Compatible with a wide range of fuel types, this filter is an ideal solution for carbureted and fuel-injected applications running on pump gas, E85, methanol, or diesel.

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!

easy to use

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.
