Purpose of the Rising Rate Regulator The Cartech regulators are designed specifically to add fuel to modified EFI engines (turbos, superchargers, and normally aspirated). The installation of an aftermarket fuel pressure regulator allows for the adjustment of fuel pressure to suit larger aftermarket injectors and other engine modifications. They are also necessary to regulate and flow increased volumes of fuel pumped by high flow aftermarket fuel pumps.
Most fuel pressure regulator install jobs fall under this category. If you are using a universal unit in your fuel pressure regulator install , the hard part is usually mounting it. When it comes to mounting your fuel pressure regulator , always use caution. The second high- pressure pump allows an even higher flow rate and is alcohol and methanol compatible, but contains no fuel pressure regulator.
A separate fuel pressure regulator must be purchased. The mounting holes are untapped on the above Holley and NOS regulators. Find the fuel pressure regulator. It is located on the passenger-side of the engine, behind the throttle body.
The PDF Documents are exactly what you would find in the product box themselves. Installation Instructions. These are arranged by part number.
A Mustang fuel pressure regulator is a vital part to your fuel system. The fuel pressure regulator is an engine management component that is found in one form or another on virtually all internal combustion engines. It is a component of the vehicle’s fuel system, and as it’s name implies, is. Vehicles used for drag racing are subjected to high g-force launches, which can reduce fuel pressure. This could occur if the fuel line between the regulator and the destination fuel rail, fuel log, carburetor, diesel or direct injection pump is positioned to run lengthwise on the vehicle, and the regulator is placed behind the fuel destination.
Order ships free when this item is included and exceeds $99. Help is just a click away! YOU can control EXACTLY what pressure levels the carb input port sees! Once the fuel pressure gauge registers fuel system pressure and there are no fuel leaks, start the engine and adjust the regulator to the desired fuel pressure ( Regulator is adjustable from 3-psi). Turning the adjustment screw clockwise will increase fuel pressure.
Once the desired fuel pressure is achieve tighten the regulator. To lower pressure , turn screw count-er-clockwise. Once desired pressure is achieve hold screw in postion with Allen wrench and lock down the nut. It is mounted to the fuel rail and contains a spring and a diaphragm. A port connects the regulator to engine vacuum and it is also connected to the fuel return line, which allows fuel to flow back to the tank.
Make sure that the o-ring is replaced and properly installed between the regulator and the fuel rail. Take your new fuel pressure regulator , push it down into place, and then back. Push the fuel line back up into the pressure regulator , and then replace that nut and tighten it up. Now replace that TTorx bolt and tighten it up.
Set the pressure mechanically like a traditional bypass regulator , then let the electronic regulator ’s demand based speed control take care of the rest! Pressure adjustments must always be made with engine idling. True pump control is finally achievable and easy to install. Regulators and fuel filters are also an integral part of the fuel -delivery system. With the advent of the latest high- pressure and high-volume pumps, all of the manufacturers now require that a. By reading manifold pressure or vacuum, the regulator will keep the fuel pressure constant regardless of how much fuel is being drawn from the.
Replace the retaining clip to secure the fuel pressure regulator to the fuel rail assembly. Make sure the retaining clip snaps over the outer ring of the fuel pressure regulator. Begin by removing the factory fuel pressure regulator , return fuel hose and fuel pressure regulator vacuum line. Use a little lube on the o-rings to prevent tearing them. Assemble the fuel pressure regulator as shown below.
Dirt and contamination is a major cause of fuel pump failure, you must completely drain, clean and fl ush the tank prior to installing the new pump. Ensure that any spilled gasoline and any gasoline soaked shop towels are cleaned up and removed from the vicinity of the vehicle! The need to work as cleanly as possible cannot be over-emphasized. The nozzle openings of the injectors are very small. Keep hands and tools clean.
Screw in the mounting hardware finger tight. This will secure the fuel pressure regulator to the fuel rail. Step 2: Put on the vacuum hose to the fuel pressure regulator. On ALL applications, it is recommended that a fuel pressure reading be taken at idle, with the vacuum line connecte (to use as a reference point) before removing the original regulator.
PressUre reGULatOr INstaLLatION step Mount the fuel pressure regulator as close as possible to the carburetor. Note: Do not mount the regulator on or near exhaust manifolds. A bracket is provided for convenient mounting.
Attach the fuel line from the outlet side of the fuel pump to either side of the fuel pressure regulator. Uses the stock fuel delivery, via raising the fuel pressure by tricking the regulator.
