It does sound like a fuel pressure issue.I would suggest that you have that checked before you go any further. A shop will have the right connectors to test the fuel pressure on you car, it just has to be done in line instead of at the shrader valve.

You have to have a fuel gauge and the correct fittings and lines to hook in line to test the pressure and a canister to collect the fuel in to measure volume I understand about the funds, i'm right there with you.

I bought a new fuel pump assembly with the filter and pressure regulator and hooked it up and gas started gushing out the pressure regulator, but when put the old one back on and it works just fine what is wrong with the new one?

Sounds like the new one is leaking new parts can be bad. I have received bad new parts myself. I have even gotten brand new cars from the factory right off the delivery truck with a bad part on them.

Yes. The old regulator in the end going into the tank is completely open and the new one goes a 1/4 to 3/8 and stops. Could this restrict or put to much pressure and cause the flow to be to much causing it to leak out the other end with it hooked to the fuel line?

It is probably supposed to be open that might be the problem right there. If the new one leaks and the old one does not I would say the new one is wrong some how.

While driving my 2004 Dodge Neon, upon initial acceleration, the fuel gauge would drop down to the red level and the low-fuel light would come on, then the gauge would move back up to where it should be and the light would go back off. Prior to this the car had been running a little rough (like needing a tune-up on an older car would feel). There was about 1/4 tank of fuel in the tank at the time of this problem. I realize the fuel pump is in the tank. The repair shop wants $1100.00 to replace the pump (the part alone is $300.00). That is really a lot of money in this economy and I can't replace it myself since the tank needs to be dropped according to the repair manuals.
My question is. Can I prolong replacing it by keeping the tank full of fuel?

I don't know the exact procedure for dropping the gas tank on a dodge neon but just because it's a tank don't be scared to do it. Get a good manual and see how hard it is. I have personally dropped tanks several times to change out a fuel pump (On a suburu they wiesely put the pump in the engine compartment-what a breeze). Anyway, it's smelly, hard, and a nast job but it can be done and it's usually not very complicated. The reason it's so expensive is because it's smelly and hard but you can save big bucks doing it yourself...though you will need a "stick with it" helper. Take a look at the steps in a manual and then prepare meticulously with the tools you'll need and give yourself at least two days the first time you do it.

Here is a video of the job being done on a similar car with instructions below on how to do the job on your car.

Check out the diagrams (Below). Please let us know if you need anything else to get the problem fixed.

Are you using oem fuel pump? Make sure the tank is clean. Check for good voltage and ground at the fuel pump. Check for voltage drops, everywhere, to the pump. As an example, check voltage drop across load side of fuel pump relay, shouldn't be any. I don't have the exact spec in front of me, very small if any.

Make sure fuel lines aren't clogged. Fuel filter clean. Check proper fuel pressure. That's all I can think of at the moment.

Hello my name is Dave

Your fuel pump is located in the fuel tank and the filter/regulator is on top of the tank where the fuel lines come out. To replace the pump you have to remove the fuel tank. I have attached a diagram of the pump so you can see what it looks like. I am also including links to our tutorials on both replacing and testing your fuel pump.

Her is the one for testing your pump, just to double check that that is your problem, nobody wants to do unnecessary work;

And here is our tutorial on replacing your fuel pump;

It is built into the fuel pressure regulator and lives inside the gas tank. It is not meant to be a regular maintenance item.

On older vehicles, other than with diesel engines, you will never solve a running problem on a Chrysler product by replacing the fuel filter. They last the life of the vehicle unless they corrode through and start leaking.

Good evening,

The filter is on top of the fuel pump module at the fuel tank.

REMOVAL

Warning: the fuel system is under a constant pressure, even with engine off. Before servicing the fuel filter/fuel pressure regulator, the fuel system pressure must be released.

1. Refer to Fuel System Pressure Release. The fuel filter/fuel pressure regulator is located on the top of fuel pump module. Fuel pump module removal is not necessary.
2. Raise vehicle on hoist.
3. Disconnect fuel supply line at the Filter/Regulator nipple.

4. Depress locking spring tab on side of Fuel/Regulator (Fig. 2) and rotate 90° counter-clockwise and pull out.

NOTE: Make sure that the upper and lower O-rings are on the Filter/Regulator assembly.

INSTALLATION
Lightly lubricate the O-rings with engine oil.
1. Insert Filter/Regulator into the opening in the fuel pump module, align the two hold down tabs with the flange.

3. Connect the fuel line to the Filter/Regulator.
4. Lower vehicle from hoist.
