Aeromotive 13134 is a extreme flow electric-pump EFI return-style regulator. Its pressure spring, return restriction and fuel-port layout must suit the intended pump and operating pressure; a broad horsepower headline does not certify an unspecified complete fuel system.
| Application | Requirement |
|---|---|
| Source-matched high-flow EFI system | Verify actual pump operating flow and pressure, required spring, fuel approval, return-line capacity and fitting clearance. A vehicle year/model alone does not establish compatibility. |
The current exact primary page restricts use on emission-controlled vehicles to a dedicated race vehicle; generic direct-replacement language elsewhere must not be read as blanket street approval.
| Detail | Value |
|---|---|
| Brand | Aeromotive |
| Manufacturer Part Number | 13134 |
| Configuration | Extreme Flow Electric-Pump EFI return-style regulator |
| Fuel ports | Two ORB-10 side inlet/outlet ports and one ORB-10 bottom return |
| Pressure adjustment | 30–75 PSI installed spring; primary high-range headline says 75–125 PSI but its included-spring bullets and exact manual say 75–120 PSI |
| Return restriction diameter | 0.313 inch |
| Pump-flow scope | Current primary says 2.5–6 GPM, repeated older overview says 3–6 GPM, and the exact manual describes 180–300 GPH bypass flow. These are differing source ranges and conditions, not a guaranteed identical pump-flow rating. |
| Manifold reference | 1:1 vacuum/boost |
| Pressure gauge | Separate |
| Condition | New |
The current primary's generic ORB-12 field conflicts with its detailed ORB-10 description and exact manual. The exact ORB-10 body ports govern; do not select ORB-12 adapters from that generic field.
The exact manual lists pump gasoline, race gasoline, E85 and alcohol/ethanol; verify approval of every other system component independently. Regulator approval does not establish approval for a pump, filter, hose or any other fuel-system component.
A pressure gauge, fuel lines and vehicle-specific installation hardware are separate. Spring range/source qualifications above apply; do not assume a higher published limit is verified for the actual hardware. No full fuel-system package is implied by the installation drawing.
Aeromotive develops performance fuel pumps, regulators, filters, rails, tanks, fittings, controllers, and complete fuel-system components for street, racing, and custom applications. Black Ops Auto Works organizes each listing by exact part number and available application data to support accurate system planning.
What is the 13134?
It is an Aeromotive extreme flow electric-pump EFI bypass regulator for a source-matched high-flow fuel system.
What fuel connections does it use?
Two ORB-10 side inlet/outlet ports and one ORB-10 bottom return. These are O-ring boss body connections; the external hose flare depends on the selected adapter.
Does one installed spring cover the entire pressure range?
30–75 PSI installed spring; primary high-range headline says 75–125 PSI but its included-spring bullets and exact manual say 75–120 PSI. The low- and high-pressure springs are alternative configurations, not simultaneous outputs.
What pump flow is documented?
Current primary says 2.5–6 GPM, repeated older overview says 3–6 GPM, and the exact manual describes 180–300 GPH bypass flow. These are differing source ranges and conditions, not a guaranteed identical pump-flow rating.
Are the fuel-port fittings included?
Fuel-port adapters, plugs and hoses are not promised as a complete plumbing kit. The manufacturer identifies the two reference adapters separately from the required fuel connections.
How is the boost reference connected?
The exact manual directs the reference to the intake-manifold plenum behind the throttle body for 1:1 vacuum/boost compensation. This is different from a carb-hat pressure arrangement.
Can the bottom return be blocked?
No. Route the return back to the tank using the correct clearance, adapter and line capacity. Close only unused fuel inlet/outlet ports using the matching O-ring boss plugs.
Which qualifications remain?
The current primary's generic ORB-12 field conflicts with its detailed ORB-10 description and exact manual. The exact ORB-10 body ports govern; do not select ORB-12 adapters from that generic field. The exact manual lists pump gasoline, race gasoline, E85 and alcohol/ethanol; verify approval of every other system component independently.
