FAQ

What is the AD17SAR?

It provides adjustable diesel fuel-pressure control from 7 to 70 psi. Four pressure ports and a separate return allow different plumbing layouts; the pressure-gauge port is distinct from the five main -8 ORB ports.

What application does this version fit?

Compatible aftermarket diesel lift-pump systems that do not already incorporate this type of regulation. Configure for pressure-side or regulated-return plumbing as shown in the manufacturer guide.

What is included with this listing?

Diaphragm fuel-pressure regulator; Mounting bracket and supplied bracket screws; Two movable -8 port plugs.

Does this replace every similar-looking component?

No. Match the products function, connections and complete system configuration; appearance alone does not establish compatibility.

How should pressure or electrical setup be selected?

Use the verified ranges and connections above, then follow the exact guide. A warning threshold, regulator range and engine operating pressure are different specifications.

What should be checked before installation?

Check the installation location, connections, required tools and supplied components against the exact guide. Do not adapt a different vehicle kit solely because the pump looks similar.

Are additional parts supplied automatically?

No. A gauge, sender, additional fittings, separate regulator or complete fuel system is included only when expressly named in Whats Included.

What should be checked before driving?

Follow the priming and startup procedure, inspect every fuel and electrical connection, verify pressure with appropriate equipment, and check for leakage and hose abrasion.

Installation Instructions

1. Select the pressure-side or regulated-return arrangement in the manufacturer guide.
2. Mount the bracket and regulator securely without overtightening the bracket screws.
3. Source the required hose fittings separately; regulated-return use may require another port plug.
4. Install a pressure gauge, set pressure to the engines actual requirement and check for leaks.
