Fuel pressure regulator vacuum line diagram. The three lines coming out of the rectangular plastic "vacuum distributor" box are all hard plastic. I think one goes to the fuel pressure regulator, one goes to the EVAP and this final one must go to the HVAC system by way of the vacuum ball. I'll try pulling on the hose and see if I can find its end and then try connecting it to the vacuum ball. There is a main fuel line, from the fuel tank to the fuel rail. Also, a return fuel line, from the fuel pressure regulator. This return line is located, downstream of all the injectors. Most fuel pressure regulators, use a diaphragm and spring combination within its housing. Also, with a vacuum source on the top side of the diaphragm.

550-937F Fuel Pressure. Seems like a silly question, but I've searched and cannot get a straight answer. When setting fuel pressure on a Terminator X Fox body kit, does Holley want it set to 43 psi with the vacuum line on the fuel pressure regulator or off? 12-18-2020, 01:08 PM #2. andrewb70. With this fellas efi setup ( stock type, a fuel injector per cylinder) the fuel pressure regulator vacuum line is hooked up to the intake manifold so the fuel pressure can increase at WOT. The pressure with the vacuum line connected should be somewhere around 32-35 psi, and it should jump up to around 40 psi with the line disconnected ... 2. How To Check Fuel Pressure. Most car models have a test port on the fuel injector rail for the testing of the pressure. If your car does not have it, check the manufacturer's guideline. You may need to remove the fuel line and use an adaptor for the testing. Testing the fuel pressure.

February 3, 2020 - A vacuum controlled fuel pressure regulator is used to compensate for the fluctuations in vacuum pressure. But while the engine is idling, less fuel pressure is required, the engine's vacuum will assist the valve's opening, allowing more fuel to flow back to the tank through the return line.

Been trying to solve this since last year (not a problem in the summer). When I crank the truck on cold mornings to let the windshield defrost the truck will crank fine but then the idle will slowly drop to 400-500 then surge back to normal (1000-1500). This repeats over and over until one of the drops is low enough to kill the motor. Which means I have to go back out in the cold and crank it and stay till it warms up. This only happens on a cold morning, cold start. No problems after the truck ...
