Question: Once you pulled the tray out of the tank, did you re-install the tray with the fuel pump and sending unit or did you leave it out?

The reason I ask is because the tank that was in my YJ originally was missing this tray. What I experienced was that once I reached a low fuel level state (approx 1/4 tank) the engine would become fuel starved and sputter-stutter briefly on turns at speed and sometimes from a dead stop. My understanding is that this tray holds some fuel near the intake to avoid this situation, and in an off-camber situation, helps keep fuel where it's needed.

I don't think this is causing your latest "bucking" in second gear, but I'm curious to hear what Idaho and Que have to say on this.

To be honest buddy I believe you are right. I left mine out it was trash. I think that is causing my problem because I did have low fuel level. About 1/4 a tank. Might just have to keep on the full side.

1/4 shouldn't mater. see if he is right. 20 grade low on fuel might leave the pickup for the pump dry but not on any normal driving. run a full track and see if you have a issue. post back what you find.

One more thing. See if it happens on turns and if the idle increases when you turn the steering.

I wanted to ask you too Que. code 52 running rich is gone. But since this little mod. I now have code 22. I have ohm'd the temp sensor out at 1000 at operating temp. Disconnected battery twice to clear codes. But it keeps coming back. Whatcha think. Could this all be related?

Bought a new temp sensor while I was at the parts store buying hubs, rotors, pads, and u joints. Hell what's $20??? Ill out it on tonight and see if she will clear the code out then. Also got a new temp switch. Broke my old one connector broke off while I was trying to remove it for replacing. Now I'm scared to bow down on it I fell like its gonna break. While the shop is doing my brakes and ujoints I'm gonna see I they will replace it. That way if it breaks off its on them. Ha. Oh well I keep this updated.

I know what I experienced and it happened enough for me to source a used tank with the tray in it and replace my old one.

Just sayin'

Luuca, I dont doubt what you are saying. That is why I agreed and said to do the full tank like you mentioned. If the sock is totally submerged and the issue is still there and comes back later that is it. It sounds more like a closed loop issue when the engine warms up it is getting a wrong input from the O2 or temp sensor. If the temp stays high it will starve it for fuel if it goes low it will dump fuel.

But do you normally recommend removing that tray? Does it normally not cause issues like I had?

very curious.

Thray normally warps and pushes against the float arm. It is a different problem but very common. If you go in to the tank you are better off just popping the thing before it warps. I think that more of the issues like the warping must be coming from the alcohol in the gas. There is probably a dozen threads with the bowl warping and interfering with the arm. The warping on the tank seems to be the biggest issue with interfering with the return and causing high fuel pressure.

Hey buddy will you go back a few posts and tell me what you think about my code 52 going away and going to code 22 now. I've got a new sensor in the jeep gonna try and get it on today. Could that be some of my problem now? Another isolated problem or possibly related to all of this other stuff?
