Morning everyone,
Cleaning the fuel system is progressing very well. Tank and lines are clean and now can work on the injectors and fuel rails.
But before tackling that I want to replace the tank filter screen (pn 928 201 081 00) but I can not get the old part out. The existing part looks like a replacement part (it is a Purolator part). I have tried a 17mm wrench (stripped the sides) and large water pump plyers (deformed the outer edge of the filter screen) but the thing will not budge. started to see the tank flex a bit so I backed off.
My question is: is this filter screen glued into the tank? I am unable to find any reference to it being glued in but it is solid. Penetrating spray and cleaning the inside of the tank has had no effect.
The new Porsche part is threaded and has a single gasket but nothing on the threads.
There is a metal insert pressed into the tank the screen assembly screws into.
Not uncommon for these to seize together. Usually the insert starts to spin in the plastic tank and most consider this the kiss of death for the tank since there is no agreed upon way to fix this.
Some have tried various epoxies and sealants, results have been mixed.
Here are some photos from other threads showing the insert, first one in the proper location and the 2nd photo shows it is loose (not good...)
Jebus.... Leave it alone. Anything not caught in that screen will get caught in the fuel filter which is a much finer filter. The pump isn't protected but that's an easy replacement.
No one should ever try to remove that screen....the threads are corroded and the threaded ring breaks loose and spins. Then you can not tighten it back up and you have a fuel leak around the gasket.

Yep.
Unless you have a screen like this one. This one was from a car sabotaged in a shop with paint dust added to the tank.
Seems the way to go is not changing it. On my car the frame for the screen material is there but the screen material itself is just gone. Does that change the equation?

Fuel pump functioning well ? Injectors ? There's only one direction for the remnants of that screen to go. I would think this absence maybe an equation changer. Let's listen...

Bought the car as a non-starter for the past few (5-8) years. Believe the car was running when parked as the owner got old (not a criticism).
All that to say...I do not know how this runs. Fingers crossed as are my arms. legs and eyes...lol
Thanks for the help everyone. Appreciate it.

Reason: Add quote.
BTW, The car had fuel in the tank that was emptied. I removed the tank from the car and cleaned the tank with engine cleaner, lacquer cleaner and pressure wash and rinse. Possible the screen came out the top hole when I inverted the tank to drain. Not sure but possible.
The screens sometimes break loose and roll around in the tank.....if/when the flat closed end gets sucked up to the outlet it can cutoff the fuel....stop the car..
Have it towed and it will rollaway and magically the car starts and runs when you get it home. So people when they figure it out will fish out the screen using the level sensor hole for access.
