You are much appreciated. Everyone listed the part needed as a anti drainback valve but I couldn't find anyone (Except You) that went further and said it was located in the fuel filter regulator. The dealers knew nothing about it. No one could find an “anti drainback valve” listed. Thanks for taking care of this dummy. I feel like an expert now on the anti drainback valve located in the fuel filter regulator and I know several places where you can buy them.

|Jerry Bransford||Yes, that is the correct part.|

|Jerry Bransford||Provide a link to it and I will but from the description you gave, it's obviously the correct part.|

Would you mind looking at the picture of it on ebay to determine if it is the same part? It is listed under "Fuel Filter Regulator" Jeep

|Jerry Bransford||For $59 vs. $90, I'd take a chance on the eBay regulator.|

You can't buy just the valve itself, the fuel pressure assesmbly it is inside is sealed.

Anti drainback valve
Where can I buy a anti drainback valve. Several said it would cost under $50.00. I called around and they all want around $125.00. Where can I get one of the fifty buck ones?

Fuel pumps usually come with the fuel pressure regulator module that sits on top.
If you did not have to re-use/reinstall your old fuel pressure regulator as shown below, it was replaced with the fuel pump.

Great you mean i have to take this tank off again!! any idea the damage if i don't fix it right away?
at least i got the acceleration issue fixed.
i'll have to take pictures the next time around

When the antidrainback valve inside the fuel pressure regulator leaks, it allows the fuel that is supposed to remain in the fuel rail next to the fuel injectors for fast starts to instead drain back down into the fuel tank.

2000 jeep wrangler fuel pump replacement
Replacing the fuel pump and filter in a 2000 jeep wrangler sport 4.0 liter,
I am not a mechanic and the hardest thing I have done to my jeep before this was change my spark plugs. It took me about 8 hours from buying the parts to finish to complete this project. I wasted about 3 hours trying to figure out removing the tank and hoses. If I can do it you can do it, the estamite I got to have a shop replace the pump was 700$ total cost to do it yourself 130 for the pump 20 for the wrench to get the PVC cap off, and 2 dollars for towels.
Symptoms of bad pump/filter
Cold start engine will turn over about 6-8 time and not start, but back the key of and turn it over again and it fires up first time,
Acceleration, on less than half a tank, revs RPMs but jeep doesnít go faster than like 10 miles an hour, once you get up to speed with the help of going downhill things seem to be fine. Or if you fill the tank things seem to be fine.
1st the parts
On the 2000 wrangler the fuel pump and filter are inside the tank. This is a pain in the a$$, you will have to remove the whole tank in order to get the old pump and filter out. FULL TANKS ARE HEAVY
There are 2 filters one that sits on the bottom of fuel pump assembly unit, and one that sits on the bottom of the fuel pump itself.
Some things I didnít know about are that the main fuel line that connects to the outer pump head are that it takes a special tool to disconnect it. Well being the person I am I just used a flat head screw drive to pry it off. I donít recommend doing this I mangled it up pretty well luckily I didnít damage it.
Also in order to get the fuel pump out there is a 6 Ĺ to 8 inch PVC cap that screws onto the tank, you need a belt wrench or some other tool to get this off. I ended up using an Oil filter wrench that is meant for oil filters on tractors. It worked but the teeth of the wrench chewed a couple spots in the cap nothing serious but still it was a pain.
My tank was connected to the frame with 7 half inch bolts,
3rd tank removal
First things first put your jeep up on blocks, and disconnect your battery. If you have a lift you prolly donít have questions about this stuff. Once your jeep is on blocks take a jack and a piece of ply wood and put them under the tank, the ply wood will help distribute the weight. Unscrew the four nuts in the back and then unscrew the four nuts toward the front,
When these nuts are off the only thing holding you tank in is the hoses, this is the purpose of the jack, next there are 4 screws that hold your gas funnel in, this is the place you put the gas pump when you get gas. Take you gas cap of and unscrew those screw. You should now be able to push that piece through.
There is a plastic access panel under the jeep behind the driverís side tire, pull this down to get better access to the big hoses. There is a plastic pin that you may need to pry out to get the best access.
Once those hoses are free slowly lower the tank, only lower it about 4-6 inches just enough to youíre your hands on the top of the tank. Now you should be able to see three hoses and the electrical plug, the left and right hoses are vent hoses you can pull those off the middle hose is the main fuel line which requires that tool, or if youíre desperate and willing to possible damage the hose you can wedge it off with a flat head screw driver.
To disconnect the electrical plug you need to push the red tab down and push the black button in then pull the plug apart. When properly done the plug comes apart easy, if you have to pull really hard you donít have the black tab pushed in.
Ok your tank is completely free from your jeep. Lower the jack all the way down and pull the tank out from your jeep. You will now see the PVC ring that holds the fuel pump assembly in the tank. Unscrew this like you would any large cap. With this off you can now pull the fuel pump assembly out of the tank, BECARFUL it is full of fuel, dump the fuel out of the assembly into some other tank.
The new fuel pump that you bought has really good instructions follow those to remove and replace the pump. You have to press in the 3 whit tabs and then pull the pump head off. Inside the assembly you will see the electrical plug that need to be disconnected the tabs needs to be pressed in I used a needle nose pliers to push the tab in and disconnect the plug, with the head until removed put a piece of card board down turn the assembly upside down and gentle pound it down on the card board until the old pump comes out, this is all in the instructions that come with the new pump.
Once the new pump is properly fitted with the filter bags and put back into the pump assembly, you can put it back in the tank. The new gasket makes it a tight fit. Now that the assembly is back in the tank put the PVC cap piece back on move the tank back under the jeep and jack it up a little, reconnect the hoses. DO NOT CONNECT THE ELECTIRCAL PLUG Jack the tank all the way up. Make sure to line it up correctly put the nuts back on the frame bolts. Screw on the four screws from where the gas cap is and fill the tank with gas.
Reconnect the battery, then reconnect the fuel pump electrical plug, lower the jeep off the blocks cross your fingers and turn the key.
