It depends on the year, make and model of your car. Typically tge vacuum lines connect to the intake manifold and tge fuel lines connect to the fuelfilter, carburator,fuel pump or fuel inhection. I hope this helps

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

How do I remove a fuel pressure regulator on a 2002 dodge caravan.

Before doing ANYTHING, it is VERY IMPORTANT that you depressurize the fuel system, and be sure the engine is COLD COLD COLD before removing any lines.
The fuel pressure regulator should have one vacuum line and three fuel lines connected to it. (Some have an electrical connector instead of the vacuum line, but same idea.)
AFTER DEPRESSURIZING THE SYSTEM, with engine COLD, carefully disconnect the vacuum line (or electrical connector), then SLOWLY loosten and remove all three fuel lines, noting how they are connected. Replace all grommets & gaskets with new, then Install the fuel lines to the new regulator, EXACTLY as they were on the original, tightening the fittings to torque specifications provided for your vehicle and engine. Reconnect the vacuum (or electrical) connection, then repressurize the fuel system WITHOUT STARTING THE VEHICLE. With the ignition ON, watch for any sign of leaks. If there are ANY signs of leaks, stop them before starting the vehicle. DO NOT START THE VEHICLE IF THERE ARE ANY LEAKS, AS THERE IS A DANGER OF STARTING AN ENGINE FIRE.
Check for proper fuel rail pressure, and be certain to re-check your work within 100 miles to assure that there are NO LEAKS.
If you are unfamiliar with depressurizing or repressurizing a fuel injection system, PLEASE REFER THE WORK TO A QUALIFIED TECHNICIAN..

Where do install vacum lines install at on 2000 isuzu rodeo 5 speed transmision

which engine 2.2L or 3.2L?
4wd or 2wd?
2000 Rodeo, no job stated?, was trans removed?, engine pulled?
what makes you think the A/t trans uses vacuum? if true.
what lines to what? all vacuum lines to every thing, that it?

what country,? our USA cars , all have EPA vacuum maps under the hood, open engine hood, look up, see that sticker
and yes, some times it skips vacuum lines to brake booster or trans. its only for smog that sticker, so...
but is helplful
what you never said is what engine you have , as that greatly
effects vacuum routing, on all cars. made on earth.

im on line and there is no vacuum map.drawings
it only shows jobs, pulling lines by step, (marking them first)
no words on vacuum for tranny at all. (no vac. modulator now)
all VSV valves
FPR (fuel pump reg)
Throttle body
Electronic Vacuum Sensing Valve (EVSV)

please state number of lines disconnected,
and if both ends disconnected (a horror)
if confused, show photos. of dangling lines

open the FSM book and see each step, for connecting lines
say the booster hose (huge) it says, connect the booster
hose to the large nipple on the Plenum, (its the only one that fits)
Etc. see hose where does it go, it goes to an object.
the object has a name, like VSV for evap so that hose is called
out in the FSM

factory service manual or log in and read, it is there.

It's worth the 350. There are a lot of electrical connections that have to be removed, vacuum lines removed, fuel lines removed. Then you need to remove all the bolts that hold it on the engine. That requires that the rocker covers have to come off. Then you clean the old gasket material from the engine block, replace the gaskets and then torque the bolts with a torque wrench. Reconnecting all the wire harness connectors and vacuum lines and fuel lines and then trying to figure why it won't start. Sure you're up to the challenge?

Information about code P0171 on 2001 f-150 XL 4.2 V6 have put new injecters cleaned fuel tank new coilpack still has bad miss

PO171 is a lean fuel mixture fault code. It is not serious in most cases engine will run for years to come. The problem is caused by too much air or not enough fuel getting to the combustion chambers of the engine. There are so many causes that its hard to nail this one down. Basically your engine is sucking air in somewhere it is not supposed. Any vacuum leak will cause that.There are a lot of vacuum lines. These is usually a vacuum line diagram under the hood that will show you were they are. Also your EGR valve may not be working correctly. In smone cases the engine is pulling vacuum through valve stem seals and intake manifold gaskets. Vacuum lines and EGR are not very hard to check out as they are external engine parts. Gaskets and valve stem seals will require disassembling major parts of the engine.

Failed smog check

How well does the vehicle run?

Assuming that the engine did pass the EGR function test on the emission test results, and the MIL (Malfunction Indicator Light) or check engine light is not on when the engine is running, and if you are not sure when the last time it was that the engine had a complete tune-up, with distributor cap, ignition rotor, spark plugs, spark plug wires, air and fuel filters, then a complete tune-up would certainly help, and if the engine oil and oil filter have not been changed in a while, then they should also be changed before an emission test because long used engine oil traps carbon and it will show up as higher CO on the emission test because the emission analyzer will be able detect the higher CO from the engine oil through the PCV valve.

However, it would seem from those HC readings that there is a vacuum leak, and carefully inspect all of the vacuum lines for any cracks or damage, (especially the vacuum line to the fuel pressure regulator) because cracks in the vacuum lines seem to like to hide underneath the lines.

The emission label under the hood should have the vacuum line routing diagram printed on it, and the vacuum lines should all be checked to be certain that they are all connected correctly.

Here is the firing order diagram for that vehicle to help assist you tune-up the vehicle.

How do you install injectors in a chevy s-10 pick-up?

Removal & Installation

Exploded view of the fuel rail and injector mounting

Take care when servicing the fuel rail assembly to prevent dirt or contaminants from entering the fuel system. ALL openings in the fuel lines and passages should be capped or plugged while disconnected.
  1. Before disassembly, clean the fuel rail assembly with a spray type cleaner such as AC Delco® X-30A, or equivalent. After removal, DO NOT immerse the fuel rail in liquid solvent.
  2. Properly relieve the fuel system pressure and disconnect the negative battery cable.
  3. Remove the air intake duct, as necessary for access.
  4. Tag and disengage the fuel injector electrical connectors.
  5. Disengage the fuel pressure regulator vacuum line, then tag and disengage all other necessary vacuum hoses.
  6. Loosen and remove the fuel rail retaining bolts.
  7. If necessary to remove the fuel rail assembly completely from the engine compartment, or to prevent stressing and damaging the fuel lines, disconnect the fuel lines from the rail assembly.
  8. Carefully lift the fuel rail assembly and fuel injectors from the intake.
  9. Carefully release and separate the fuel injectors from the rail assembly.
  10. Remove and discard ALL old O-rings from the fuel injectors and, if disconnected, the fuel lines.
To install:
  1. Lightly coat the new O-rings with clean engine oil, then position them to the injectors and, if applicable, fuel fittings.
  2. Install the injectors to the fuel rail assembly.
  3. Carefully install the fuel rail and injectors to the intake manifold. Make sure the injectors are properly seated in their bores, but DO NOT force them into position.
  4. Install and tighten the rail retaining bolts to 62 inch lbs. (7 Nm).
  5. If removed, connect the fuel lines to the rail assembly and secure the fittings.
  6. Engage the fuel pressure regulator and any other vacuum lines, as noted during removal.
  7. Engage the injector electrical connectors.
  8. Connect the negative battery cable and cycle the ignition switch (without attempting to start the engine) in order to pressurize the fuel system, then check for leaks.
  9. Install the air intake duct.

Strong gas odor

  1. The fuel lines may have a leak: Replace leaking fuel lines and/or fuel line fittings.
  2. The engine may have mechanical problems: Check vacuum lines and fittings for leaks. Check engine compression. Check for broken fittings and mounts.
  3. The fuel pressure regulator may be operating at too high a pressure: Perform fuel pressure test and repair or replace faulty component(s).
  4. The ignition timing may be set wrong: Check and adjust ignition timing.
  5. The fuel injectors may leak: Clean or replace fuel injectors.
