Fuel filter and fuel starvation

danb · 06-13-2016, 08:59 AM

during a track session I had fuel starvation to a point where the car stalled on the track and restarted after 10 minutes. The car is running well on the street.

I removed the fuel pump assembly (which is in a good shape) and then removed the fuel filter which is totally clogged (the car has 125,000 km on bad Ontario gas).

The dealer wouldn't sell the filter separately.
My thinking is to remove this filter and install an inline fuel filter instead.

1. Does it make sense?
2. If so, what will be the optimal location for it?

Or is there a place where I can get a replacement fuel filter, may be from some other model?

Can you post a pic of what this filter looks like please?

I believe the filter that comes with this fits in the OEM spot. Most kits come with a square one that does not.

I wouldn't trust a 15$ fuel pump obviously though, but not a bad price to get just the strainer.

The fuel pump pickup on the bottom of the pump is not the fuel filter

The white plastic housing that the fuel pump sits inside is the fuel filter.

If you remove the fuel pump pickup on the bottom of the fuel pump, you will still have your fuel filter. But your pumps life expectancy will be unpredictable without the pickup filtering out debris that could jam the pump.

The fuel filter is this yellow/Orange mash which attaches to the fuel pump. it resides in the white housing that holds the pump and the fuel level sensor.

The fuel filter is made from two layer of nylon mash. the outer layer is course, the inner is finer. the dirt is trapped between the two layers.

I agree that removing this filter may shorten the life span of my pump, but the pumps are available and are inexpensive ($100 or so) and it takes half an hour to replace one.

The question is where can the auxiliary in-line fuel filter be placed?

I'm new to Z cars, don't even know through where the fuel line between the tank and the injectors is routed.

Dan, as I mentioned in my previous post, the fuel filter is the white plastic housing that the fuel pump resides in. There would be no purpose to you adding an inline or auxiliary fuel filter after the fuel pump, because there is already one there.

The yellow/orange piece that attaches to the bottom side of the fuel pump, is the fuel pump pickup. It is not the fuel filter. This is standard procedure for all production vehicles. The fuel pump pickup is a mesh to prevent large debris from jamming the pump, and the filter is always placed after the fuel pump. In the case of the Z, the filter itself is molded into the fuel pump housing.

The component you are describing that you are you contemplating eliminating is the fuel pump pickup. While this is not sold individually, a typical fuel pump pickup for a Walbro style pump will attach just the same.

Thanks for clarifying that, wasn't sure on the exact name.

phunk: thank you for the explanation.

I only noticed the fuel starvation after a sequence of right handlers on the track.
The motor is bone stock and I don't plan on touching it.
But the car is used for track days, I have other cars and bikes for the street.
So what do you suggest I should do in order to eliminate the fuel starvation on the track?

yeah, its not your fuel filter, its the tank design. Some of us have battled it since the car came out in '09, but phunks RRP solution solved the problem.

Rusty · 06-14-2016, 05:51 PM

danb, there is only 4 fixes for fuel starve.

1. Not to track the car.
2. phunk's RRP kit. Which I run, and recommend. A lot of us are running this kit with great results.

3. The Z1 kit. I don't know much about. There is a couple of threads here on it's merit.
4. Cut your tank in have and run at half capacity as someone here has done.
