Can I pick up my order or have it installed at your shop?

Absolutely. We offer local pickup on most products and full professional installation at our shop in Washington, MO. Whether you just want to grab your parts or have our techs handle the install, we’ve got you covered. Give us a quick call at 636-429-7020 or message us to schedule a visit — we’ll make sure the parts are ready when you arrive.

How do I know if this part fits my vehicle?

Unsure if it’ll fit? No problem — that’s what we’re here for. Send us your vehicle’s year, make, and model, and we’ll verify fitment before you order. We can also point you toward compatible upgrades or supporting parts if needed.

What if I need to return a product or it’s defective?

Most unused items can be returned within 30 days in their original packaging. Some products are covered by a manufacturer’s warranty as well. If something arrives damaged or doesn’t meet your expectations, just let us know — we’ll help you get it replaced, refunded, or repaired. (Tracking updates are also emailed automatically once your order ships.)

What's the lead time on custom or fabricated parts?

Many of our parts are built to order — especially fabricated or performance components. These can take additional time to produce before shipping. Lead times vary by manufacturer and demand, but we’ll always keep you updated along the way. If you’re working on a tight schedule, reach out before ordering at 636-429-7020 and we’ll confirm current availability or estimated ship dates.

The FASS Connect Lite Digital Monitoring System was designed for a simple, clean installation and provides the ability to monitor your FASS Fuel System’s filter life, fuel pressure, and other drivetrain parameters using powerful wireless technology.

The FASS Connect Lite has 5 sensor inputs that allow the use of a 0–100 PSI pressure sensor, a –40° to 260° temperature sensor, and a 2,000° exhaust gas temperature sensor. In addition to monitoring, it includes 2 relay trigger outputs for powering FASS Fuel Heaters or other accessories such as auxiliary lights directly from the FASS Connect App.

The FASS Connect App can monitor up to 8 parameters at a time—5 sensor inputs, filter life, GPS speed, and battery voltage.

The FASS Connect ECU communicates wirelessly with the FASS Connect App, providing an ultra‑clean installation and greater flexibility.

This kit includes the FASS Connect ECU and a 0–100 PSI fuel pressure sensor (additional accessory sensors available separately).

Adding a second fuel pressure sensor allows real‑time monitoring of the Extreme Water Separator's filter life, letting you know when service is needed. Sensors can be mixed and matched to create any combination you need for your application.
