Fuel Slosh

[tweiss3]

Is it common for fuel slosh to create "fuel cut" where you nail a tight corner, and half way through you feel like you hit a wall? Its been happening to me the past few weeks. Ive even had it happen with a touch over half a tank.

Normal-ish yes. There's two causes.

1. Dirty in tank fuel filter
2. Rusted out baffles

Try changing the in tank filter first.

I'll give that a shot. Can it be done without dropping the tank? I wonder if my baffles are gone, which it is very possible.

This is exactly what happened with my gtu a few years ago. It would cut out on left hand cornering.
I took the fuel pump contraption out of the tank. And yes there was some dirt on the filter. But I also looked inside the tank and found a layer of deposits under where the pump sits. This layer was so thick that it touched the bottom of the filter. The baffles were not rusted through, it just had a load of deposits sitting in it.

So i took my fuel tank out and cleaned it real good with water and paint thinner.

Ever since then, no more problems.
When i took it for a spin after I got it all back together again, I swear it felt like it had more power. lol.


So just check the filter on the pump and clean it, and check inside the tank too for rusted baffles and/or a layer of deposits. Take necessary action depending on what you find.

Remove the rear carpet, take off the left access cover, disconnect the pump, remove te 8 screws, lift the pump out. The filter will either be a yellow bag thing or yellow box on the bottom. I believe one screw holds it on.

As rotary tech said look for deposits. If your tank is nasty it'll just clog again.

Checking it out can be done without dropping the tank.
Lift up the carpet in the hatch area. Next get a screw driver and take off the plate with wire coming out of it on the driver side of the hatch area. Start the car then detach the connector that's connected to the fuel pump. Let it die. Detach the fuel lines at the pump. Take out the fuel pump contraption by unscrewing the screws (be careful not to strip them). Check things out.

awesome, sounds like i probably have 20 years of shit sitting in the bottom and i probably should just clean it out

^^ beat me to it. lol.

Very common. Happened to me a few times when I was n/a. It's the second 1/2 of the reason I went ahead and built the fuel cell/surge tank setup.

Here's my surge tank setup i put together a few years back. works like a charm!

That fuel strainer on the bottom of the pump will stop up and it won't look like its very dirty. It will get a clear varnish clogging up the screen and won't hardly let fuel come thru as fast as is normal. Soak the screen in acetone overnite and blow it out or just buy another at the store.

Don't belive it? Then take the screen off and fill it up with gasoline and notice how it will barely leak out the screen.

The usual failure is in left hand turns.
