Greetings, the trouble started out when we drove the car all day, no issues. Started home and the engine was sputtering a bit and I immediately thought more than one COP died suddenly. Limped it down about 300' and it died altogether. Welp, that probably wasn't a COP issue. Get home, scanned the CEL, P1233.

Checked F7 - good
Checked IFS - not tripped
No fuel at the rail

Had over 1/4 tank of fresh(er) so figured it was the right (passenger) fuel pump. I just didn't feel like troubleshooting any further than that, and figured the pump was probably on borrowed time anyway

Bought a pump and spanner tool from Amazon. Spanner tool is a must to get the fuel pump flange off.

Removal was largely uneventful.

Installation hint: there are two tabs on the top of the fuel pump where the connectors are, those tabs line up squarely with the fuel tank. It took us at least two hours of trying to get that flange together before we realized those tabs and notches needed to be lined up. The flange went back on the first time after that and those tabs and notches help keep the pump from rotating due to the flange being tightened.

Helpful hint: If you're removing the fuel pump (either one), you are in a for penny, in a for a pound and several times my back told me just to remove the front seat to give me some more room. It takes all of 10 minutes to take the seat out, just do it and save yourself a back spasm.

So I do all that, clear the codes, start it up: cranks, no start and CEL is on. Now I am in a pretty bad mental state. Same code: P1233.

I started troubleshooting from the beginning and somewhere, someway, somehow, F17 blew. Replaced that, and the car fired right up.

YMMV.

Good day Gents- I bought a Delphi fuel pump module for my 2002 (passenger side) but noticed it came with a black gasket, not the green gasket which Ive seen on a couple of videos.
My question- Im assuming I need the green gasket- Am I correct?? And FYI- so far Ive gotten to the point of loosening the lock ring- everything up to this point came apart nicely.
Thank You All,
Brock

Hey Brock, I just replaced this assembly the other day and ended up using the new black gasket that was supplied. Everything went together with no problems.

I have a 2004 T-bird. I am having a hard time finding a sender unit for the fuel gauge. It is not the one attached to the fuel pump it is the second one. Part # is CFT40.
Does any one know where I might be able to find this part?

I have a 2002 in the same predicament. Cannot find any replacement part for the left side fuel tank sending unit. Please let me know if you find anything.

Is the fuel tank sending unit rebuildable? Can I just replace the filter and assume it is working well. Is there a way to bench test the unit?

You're talking about drivers side? Drivers side doesn't use an electric pump. It's a passive system that uses the flow of fuel from pass side electric pump to transfer fuel from drivers side tank to pass side tank. Other than the fuel level float mechanism, it shouldn't go bad.

1) Request assistance in obtaining/confirming the OE Part Numbers for the Right and Left Fuel Pumps for '02 Tbird.

Are these correct OE Numbers?
YW4Z-9H307-BB (right)
YW4Z-9275-BE (left)

2) Request assistance in sourcing replacement Fuel Pumps...I have found aftermarket replacement for RIGHT pump on Amazon, but nothing for LEFT one.

Thank you.

Can someone please tell me where the Fuel Pump Driver Module is located in a 2004 Tbird and maybe a part number for it??? Thank you.

Parts geek has L sender on eBay 62.95 part # ps 140

The left is a transfer pump according to ebay

 

[HeyTBaby]

Where can one purchase the float aka fuel gauge sending unit for the Left/Driver side; or the entire assembly for the Left/Driver side? I think the OEM for just the float/sending unit is yw4z 9275 AA and for the entire assembly yw4z 9275 BC, right? The passenger side/right pump was/is PS 149; the left may have been PS 117, right?

Need some advice.....I replaced my passenger side fuel pump on my 2002, car finally starts up and runs. BUT, when i fill it with gas at the pump, the gas leaks between the ring and the top of the fuel pump. It does not seem to leak when i dive it. I tightened the ring as tight as i could with the tool from Amazon, but still leaks only when i fill it at the pump. A black gasket came with the kit, not a green one that was on the car, not sure if that matters or not.

I planned to check the gasket but now I cannot get the fuel lines to disconnect. I push in the tabs that the elbow connectors insert into, but the lines will not come loose at all. Is there a trick that anyone knows that can help me get these disconnected? i'm at the point of trying to figure out how i can cut the fuel line and figure out if there is a way to use a fuel line connector to reconnect, something like this: Amazon.com: Fuel Line Connector for 5/16" OD Nylon Tubing Hose Union Quick Connect, Fit for 8mm OD Nylon Tube/Gas Line Pack of 4 : Automotive

ANY help would be appreciated.

I bought the Delphi FG1340 Amazon.com: Delphi FG1340 Fuel Module : Automotive

Do you know if the divers side sends a message to the fuel gauge to indicate the level of fuel in the tank (as well as the passenger side)? I replaced the passenger side fuel pump but the fuel gauge only shows 1/2 a tank when the tank is full. When the tank goes to half full, the fuel gauge starts to read correctly.

Yes, drivers side has a float just like passenger. Your symptoms are typical for a failure of the drivers side float, not the pump. It could be corroded or possibly the float is stuck to bottom of tank. I've not seen a driver's side pump + float for sale in quite some time, at least not for an 02. I've not seen definitive part info for just the float either. See this post for more detail on float operation vs. the gas gauge. https://forums.fordthunderbirdforum.com/threads/2003-fuel-gauge-will-not-go-below-half-level.13201/
