SOURCE: missing vacuum hose from fuel pressure regulator on 1991 mercedes

the fuel pressure regulator vacuum hose usually runs to the upper air intake somewhere, check for the fitting on the upper air intake or throttlebody.

SOURCE: no gas going through fuel pressure regulator on 1995 dodge carava

I doubt the regulator is bad, the fuel pressure regulator is after the injectors in the return stream to the tank, more likely it is the fuel pump.

SOURCE: fuel pressure regulator

Have you checked the fuel pressure? If it is high and fuel is not returning, the regulator is bad. If it is low and fuel is not returning, the pump is bad.

SOURCE: Checked Fuel Pressure Regulator on 93 Ford Tempo GL 2.3 Liter.

As far as I know without checking it personally it sounds like it could be one of three things (in order from easiest to hardest). Clogged air filter, worn timing chain, leaking head gasket. To check for the third go to Auto Zone and get them to do a compression check, its free. I can't remember off hand but if the 93 has a TPS (throttle position sensor) that could also cause an irratic idle.

SOURCE: fuel pressure regulator had no vacuum line connected

another engineers wet dream. think of it this way . what is normally in the intake when the engine is running.. answer vacume, hence the regulator gets its vacume without a hose connected to it as its already in a full time vacume hose required . ps be carefull to seat the regulator and o rings securely into the housing befor you reattach the secureing metal clip.
good luck chris

Where is the fuel pressure regulator located on a 1988 Dodge B-150 van, 5.2 liter? I've been told it's on the fuel rail. Where is the fuel rail?

If you have throttle-body fuel injection, you don't have a fuel rail. The fuel pressure regulator should be mounted to throttle body.

Idles but bogs down with a load

How about a defective fuel pressure regulator, buy a fuel pressure test gauage from Autozone and test the fuel pressure under a load and at idle..

What does the fuel pressure have to be on a 1997 dodge intrepid

  1. Without vacuum applied to the regulator, the 3.3L engine fuel system operates at 55 psi (379 kPa). With the engine idling and the manifold vacuum applied to the regulator, the system operates at approximately 46 psi (317 kPa).
  2. Without vacuum applied to the regulator, the 3.5L engine fuel system operates at 48 psi (331 kPa). With the engine idling and the manifold vacuum applied to the regulator, the system operates at approximately 39 psi (269 kPa).
  3. The fuel system pressure varies with the different amounts of manifold vacuum applied to the regulator. If the pressure is NOT correct, record the pressure and remove the gauge.

In the throttle body. You may need to have someone show you where exactly it is.

1988 Dodge P/U with a 318. Getting fuel to carb but only when I try and start it, no fuel at all when I just turn the key to activate pump. Not a mechanic by no means but have been following diagrams and...

You mean throttle body?

If you cycle the key ,you should hear the
fuel pump (in tank) for 3 seconds,then it
will shut off

I assume that the filter is under 30,000 miles
or 4 years old

You will need a pressure gauge if you hear
the pump come on

If you have 40 lb at the fitting near the manifold
you unplug the vacuum hose at the pressure regulator

If it is good the pressure should go up some
about 60 lbs

You still could have a failing fuel pump
I would go with that if it is 21 years old

I have a low pressure fuel code and my 1988 suburban will not run very well what should I do?

Start by replacing the fuel filter and check vacuum hose to fuel pressure regulator, if that does not solve the problem, check the fuel pressure, borrow a Fuel Pressure Tester from AutoZone, Checkers or similar autoparts store and check fuel pump pressure. They will tell you the correct pressure.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

Hi i have a 1988 ford f150 it idles up and down and always smells like gas also when you floor it or tap the gas after idling for a while black smoke comes out the tail pipes. i'm so sick of it running...

Check fuel pressure regulator by removing the vacuum hose. If idle does not change or fuel comes out of regulator replace it. Otherwise check your injectors one at a time while car is running. If idle does not change replace it.
