Installing a fuel pressure regulator into a 1998 GMC with a 5.7 engine upon removal of the old regulator and beginning to install the new regulator it says to hook the hose to the regulator upon remov?
Most of them are under the upper intake manifold but there is not a hose connected to it, point connection down

Does the intake manifold have to be removed in order to replace the pressure regulator in a 1998 GMC jimmy?
Answer . Yes... If your trying to fix a starting problem you might want to wait on replacing it... I replaced mine and it didn't change a thing. Only attempt the installat…ion if you have a good memory because there are alot of bolts that need to be taken off... hardest part of the job is removing the intake cover, Fuel hose placement along with electrical lines running overtop make this very difficult. hope that helps.. - Christian ctjames88.com
it is under the upper intake manifold, if you have a vortec engine
Answer . it is under the black plastic upper intake, that the throttle body bolts to
Answer . Vortex engine? Got me. I thought Vortex was just a brand of supercharger. . I believe you mean Vortec engine.. GM also called this the L31 (they use 3 letter/num…ber codes for everything) . This system used a SCPI (Sequential Central Port Injection) system... and the fuel pressure regulator is on the central unit, which is INSIDE the intake manifold- you have to remove the upper intake manifold to get at it (plastic part), and the Fuel pressure regulator will be on one side of the central unit where all the fuel lines go to, it has a tube on it open to the intake manifold (to read intake vacuum)
Answer . The Fuel pressure Regulator is located between the carburetor and distributor. Mounting screw is beneath the retaining bracket leaving about 3 inches to work with…. . Remove distributor cap and rotor for access to retaining screw. . Remove fuel line connected to regulator . Remove rubber hose between throttle body and regulator . Using a #30 Torx bit (1/4 socket type) remove retaining screw located beneath the regulator mounting bracket. Space is very limited so use of 1/4 inch breaker bar may be necessary.
This fuel pressure regulator is a component part of the SFI (sequential fuel injection) assembly, sometimes referred to as "spider". It resides inside of the air intake plenum… and is accessed by removing the upper half of the intake.
Check along the Fuel Rail, see if the part you have matches the part attached to the fuel rail. Alot of Toyota's models where put in that locationi, since it does regulate fue…l pressure. If you can't find it, go to AutoZone and ask them to pull up your vehicle in the computer and print out the location of the Fuel Pressure Regulator, if they can't then go to the library and see if they have a chilton's manual for your vehicle and look it up in the repair manual. Good Luck.
i think that all of them are in the gas tank with the fuel pump. It is in your plenum, which is the intake that your throttle body sits on. it is on the backside of the injec…tion unit, sometimes refured to as a spider. it is a real job and does take time and defenite know how. you can find it in a manual. the plenum is the black cover on the very top of your motor.
Remove the fuel pump and relieve the fuel system pressure. Disconnect the fuel line then fix the fuel pressure gauge. Reconnect the fuse to the fuel pump and start the engine …to check leakage. Tidy the surrounding of the fuel pressure regulator.
Putting a gasket fuel pressure regulator in a car is easy. All youdo is take off the hose and unclasp the old one and reattach a newone.
The regulator is under the plastic upper intake manifold. It is in the end of the injector housing or pod.

There is a snap ring holding it into the end of the fuel rail. if you take the motor mount bolts out and jack the engine up you can get at it pretty well.

I have a 1988 Chevy Full size blazer. It has a 350 5.7 that is brand new crate motor. I have the TBI system on it. Here's what it's doing. I start the truck Idles fine (I chan…ged the IAC and the TPS) bring up the RPM's to around 2000 and hold it for a few seconds and it start back firing and popping. It seems like it's running out of fuel and leaning it self out. I put a new fuel pump in last year so i believe it has decent fuel pressure (although I don't know this cause i don't have a gauge on it.) But, Assuming that the pressure is good, what else could be the problem? Fuel Regulator in the TBI? Would this cause a lean condition. It also seems that is has less power then it should have.

Hi to perform this start by disconnecting your battery. Then releasing pressure from the fuel lines. There should be a valve on one of the lines on top of the manifold. Get a …rag to catch the fuel as it comes out.. 1) loosen the air box hose clams and remove the air intake . 2) loosen all sensors and accelerator cable from intake . 3) remove all the 10 mm bolts on the intake manifold and disconnect spark plug wires from distributor cap.. 4) their is another 10 mm nut between the fuel lines remove it ( note it helps to loosen this bolt before removing all the other 10mm bolts)as well as the two 5/8 bolts(brass fittings) on the fuel lines connected to the intake manifold and set them aside. 5)lift the wire harness and lift the whole intake up clearing the center of the spider injection( life and push towards firewall to help clear the radiator outlet hose). 6) set the manifold aside and clean and replace the gaskets . 7) remove the clip from the fuel pressure regulator and remove the old unit (note there is a small o-ring inside remove it may be stuck. . 8) lift the harness up to give you clearance and carefully install the intake manifold( be very careful the gasket may want to fall and cause a bad air leak). 9) Torque bolts in sequence and to proper torque specs. . 10) connect all sensors and throttle body cables and battery . 11) let fuel pump regain fuel pressure by turning the ignition over and off without turning on the vehicle then start the car.

super easy...two lines and done. The FUEL line coming from behind the drivers side strut tower is your fuel FEED line. Ther is another line right under it but its not a f…uel line its a evap line. The FUEL line going from the engine to the filter is the RETURN line. Hook those up accordingly and add the vacuum line...and you're ready to go.
