This vacuum line as weve seen discussed in several threads can get brittle with heat and stop providing accurate vacuum signal to the fuel pressure regulator located near the fuel filter. Accufab has developed an adjustable universal fuel pressure regulator for use on custom applications that require -4 in and -4 out.
Aeromotive 13138 - Aeromotive A1000 EFI Fuel Pressure Regulators.
Throttle body fuel pressure regulator. The TBI Throttle Body Injection unit. Apply penetrating oil to the screws that hold the top on the fuel injector pod. Allow this to soak while you continue.
Follow the service manual procedure to relieve fuel system pressure. This generally involves disconnecting power from the fuel pump and starting the engine to use the remainder of the fuel in the line. Aeromotive 13138 - Aeromotive A1000 EFI Fuel Pressure Regulators.
Fuel Pressure Regulator A1000 EFI 40-75 psi Return Style Inline Aluminum Black Anodized Each. The fuel pressure regulator is a vacuum-operated diaphragm so that during cold start operation maximum fuel pressure and volume are supplied. Once the engine starts and the manifold vacuum is available the diaphragm opens a valve and allows unused fuel to return to the tank.
What is the fuel pump pressure for TBI. The fuel pressure regulator is set for approximately 12 psi 30 psi on 94 95 BBC trucks. With a service range of 9 to 13 psi being considered good.
This vacuum line as weve seen discussed in several threads can get brittle with heat and stop providing accurate vacuum signal to the fuel pressure regulator located near the fuel filter. It had to be special ordered from BMW in Germany so it took a while to get. Fuel pressure regulator on a 2008 buick enclave.
The regulator is usually mounted on the fuel rail in multiport EFI Electronic Fuel Injector applications or the throttle body assembly in throttle body injection TBI applications. Some fuel injector types require pressure regulator replacement as.

State Warehouse Fuel Pressure Regulator Spring Replace for The TBS 10320 GM from 11-12psi to 14-15psi Fuel Pressure Fit for 28L 43L 50L 57L 74L TBI Motors Length 2 Outer Diameter 1. 45 out of 5 stars. The DCS gauge between the throttle bodies reads the regulated pressure and that pressure can be only as high as the fuel pressure regulator has been set for.
If it is reading over about 12 psi then the regulator has at some point been changed from the factory setting. The rear driver side throttle body is where the pressure regulator is located. Typically youll find the fuel pressure regulator on the top of the TBI unit.
Its housed inside the fuel meter cover usually its casting has a ring over each injector and should be replaced as a unit meaning fuel pressure regulator and fuel meter cover since the fuel pressure regulator is pre-adjusted at the factory and removing it from the cover could damage the regulator. The stock fuel pressure regulator consists of a diaphragm with a spring beside the injector. Engine vacuum pulls the diaphragm back and keeps the fuel pressure consistent with the engine vacuum.
The easiest way to make it adjustable is to just do away with it and replace it with an external regulator. TBI fuel injection is a type of fuel injection system where the fuel is injected into the throttle body. The throttle body fuel injection system or TBI as referred to by GM or CFI by Ford works using a single or pair of injectors.
If the line fails two things will happen you will have a vacuum leak that can lead to other issues and the fuel pressure regulator will not reduce fuel pressure under vacuum conditions causing a rich condition. Id pull the line off find a brass fitting of the appropriate diameter and then use some silicone vacuum tubing to replace the. Remove the air cleaner assembly from the throttle body injection unit to gain access to the fuel pressure regulator.
After removing the air filter housing youll see the fuel charging assembly which includes the throttle body and fuel injector. Usually the fuel injector mounts on top of the fuel pressure regulator. The throttle body injection assembly typically consists of the following.
Throttle body housing fuel injectors fuel pressure regulator throttle positioner throttle position sensor and throttle plates. The THROTTLE BODY housing like a carburetor body bolts to the pad on the intake manifold. It houses the metal castings that hold the.
5-4 FUEL SYSTEM AND THROTTLE BODY FUEL PRESSURE REGULATOR The fuel pressure regulator consists of the spring and valve. It keeps absolute fuel pressure of 300 kPa 30 kgfcm2 43 psi to be applied to the injector at all times. When the fuel pressure rises more than 300 kPa 3 0 kgfcm2 43 psi the fuel pushes the valve in the regu-.
Rochester Throttle Body Model 100 200 220 TBI Fuel Pressure Regulator 1981-1995. 25 off previous price 1499 25 off. Free shipping Free shipping.
I have narrowed down the options to 3 choices. Stock replacement 11-14psi - This provides 12psi in a stock regulator setting. Performance15-20psi - This provides 18psi in a stock regulator setting.
High Performancelate model 454 28-34psi This provides 30psi in a stock regulator setting. Specify your choice of spring when ordering. TBIs have the advantage of having the fuel pressure regulator built in.
Note that for either port or throttle body injection you can use multiple throttle bodies to support your power levels if your manifold configuration can be adapted for them. When selecting a throttle body there are a. ACDelco 217-382 12PSI Fuel Pressure Regulator Kit Fits All GM 220 Throttle Body Remanufactured.
OEM GM Throttle Body Fuel Pressure Regulator with Gaskets. Step 1 - Locating the Fuel Pressure Regulator. Finding the fuel pressure regulator is not that difficult.
Follow the fuel line to the throttle body or carburetor. The regulator is most likely attached near the throttle body assembly. Step 2 - Testing the Vacuum Line.
You first need to test the vacuum line leading into the fuel pressure regulator. If the injectors are below the throttle blades as in a multi-point EFI system then you should connect the vacuumpressure port in the regulator to reference manifold vacuum or pressure. If the injectors are located above the throttle blades as with those self-learning throttle body style fuel injection units like FASTs EZ-EFI 20 then the small port on the regulator should be left open to the.
Universal Fuel Pressure Regulator. Accufab has developed an adjustable universal fuel pressure regulator for use on custom applications that require -4 in and -4 out. This regulator is anodized.
Add to Wish List. Showing 1 to 5 of 5 1 Pages. Each system ships with the a custom black EFI bypass fuel pressure regulator high-flow billet fuel filter filter mounting bracket plus all the required port fittings and o-rings the deluxe wiring kit not shown and Aeromotive fuel pressure gauge.
Ideal for popular throttle body EFI conversions systems that make the move to EFI so easy. These DCOE Throttle Bodies are a direct replacement for the Weber DCOE and Dellorto DHRLA carburettors. Typically used in applications when converting or upgrading from DCOE and DHRLA carburettors to Electronic Fuel Injection EFI with the fixing bolt patterns matching those seen on the Weber DCOE DHRLA Carburettors making these the ideal replacements for manifold mounted.
