Engine Performance problem
1996 Dodge Avenger 6 cyl Front Wheel Drive Automatic 160000 miles
Hi I am just wondering where the fuel pressure regulator is on a 1996 dodge avenger es. I believe I seen one down by the fuel filter but not sure. I looked all over on the fuel rail and fuel lines and cant find one. I have never had to change on before so Im not sure where to look. If anyone can help I would be very grateful. Thank you in advance.
Please let us know if what the final fix was for your car so we can better assist others. Thanks!

This pic looks like its the 2.0L 4 cylinder. The 2.5 does not have a fuel rail service port for checking fuel pressure you need a special adaptor for it. The way mine is on the car is once the fuel line hits the fuel rail it travels in a " U" shape from the rear to the front and just stops. I can not see anything that resembles something like a regulator at the end. I know where the 3.1 I thinks its 3.1 is and the 2.0 but my manuel says nothing about where it is on the 2.5. But I will recheck it just incase but please reply if it is somewhere else. Thank you for your help and I am sure we will figure it out lol ( If we have not already do to my " ignorance" however its spelt. Thank you again. If I need to post a pic of what my fuel rail looks like I will post one.

Thanks for the info.............
Okay my friend......it looks like it is in the fuel tank and part of the pump. See below.
Is this what your rail looks like
Fuel Pressure Regulator
Fuel pressure regulator is a mechanical device, used to maintain a constant pressure across fuel injector tip. Spring and rubber diaphragm will move from an open to closed position keeping fuel pressure constant. Excess fuel is returned to fuel tank.
Regulator may be located on fuel injector rail, outside fuel tank (between tank and rear of vehicle), or with in-tank fuel pump module. On regulators located in fuel pump module, regulator includes an internal fuel filter. Excess fuel is routed directly into fuel tank without using a return line. See Fig. 2 .

In-Tank Fuel Pump
Fuel pump is a positive displacement, immersible pump with a permanent magnet electric motor. Fuel is drawn in through a separate filter/strainer at bottom of fuel pump and pushed through filter to fuel outlet line (to fuel injectors). Voltage to operate pump is supplied from fuel pump relay. On some models, fuel pump relay is activated by ASD relay.
On some models, a fuel pump module may include a combination fuel filter/fuel pressure regulator, fuel pump reservoir, a separate in-tank fuel filter, pressure relief/rollover valve, fuel gauge sending unit and fuel supply line. See Fig. 3 .

Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
If you notice one is about the fuel pump. I have expanded that and put that below for your review.

Well this is exactly what my fuel rail looks like. I had called on the recall but they told me there were not any recalls for my vin. But thank you again for the idea to call on that. Also if anyone has read my hesitation question I had a month or two back this is where I am right now on this problem. As far as checking the regulator goes I am almost sure its shot. Once I have figured it out I will post what the problem was. Thank you again and great job ImpalaSS your awsome.

Thanks again. Good luck on the vehicle

Well it didnt make a difference so I dont know where to go next. I found it right at the fuel filter. Anyways, Im not sure where to go next as far as checkin the fuel pressure. Like I said in passed posts I have all the power off the throttle and 0% after mand about 40% throttle so anyone with some ideas lol. Well let me know what you think of it. Like I said I can red-line with slow and gentle throttle but as soon as I floor it the car falls off and cant even move no matter what gear im in. Well once again ty in advance.

Just updating on this post sorry it took me soo long I have been really busy. I just got another car so I have been doing stuff with that. So I'm just gonna tell you whats going on now and what I may have left out in last post. Well What made me think the FP regulator was bad was when took the hose off it leaked a bunch of fuel out. But I guess thats just the return line. The battery is good I know that for sure. I charrged it fully yesterday and went out today and it has drained enough to be unable to start. But what makes me wonder is after I canged the EGR valve a few months ago I started is up and took it for a drive. All was as usual maybe a little better so I was hoping it would straighten itself out. I pulled in my driveway and let it run all the sudden my horn was blaring like louder then I have ever heard it blow. So I took out the relay/fuse for the horn and alarm system. Could this be a sign for something or no? Thank you again

Well screw all the stuff I have done to it except it only makes my car that much " newer". I had just went down and purchased a new distributor for quite some amount of money. Slapped it in like a over excited child in toys are us. Held my breath till I was about to pass out and turned the key over. Bammm started running funny and I wanted to just take a hammer to the whole project. All the sudden it kinda sputtered and must of cleaned up and runs like new now. Even better then new. So thank you all for the help you really did a great job. Best car forum site ever. Thank you again and great job.
