No engine power..fuel issue ?

Early cars had 36mm thread, and fittings for that are long time NLA. The thread did not depend on pump or filter AFAIK. Your leak could be due to a crack or other material problem with tank, or the hose, or the rubber washer between the fitting and the tank . The electrical connections in your pic say that there at least was once a pump inside. If you have not seen one inside it may have failed and been removed. Note that the hose from tank to external pump is different between filter only in tank, or in-tank pump - 92835655004 with a pump, 92835655005 with filter only. Make sure your leak is not coming down from somewhere higher up - a crack, or a leak at the gauge sender area. Some people improve the seal of the threaded insert by fitting a jubilee clip around the tank plastic on the outside there.

And should I use the curved fuel tube 92835655005 with this strainer :

PET says the hose for use with strainer ends in 05. Not clear when the thread size changed, PET says from chassis no 92881-01288, or 92882-00054 or 92882-08528 - from these chassis nos onwards, I think 92881 means 1981 , so your 80 may have the 36mm thread, where parts are NLA. You will have to remove the fitting and measure - your tank MAY have been replaced, if you are lucky!

I stripped the threaded insert in my tank once, and was able to seal it with a 2 part epoxy called PC11 - never leaked a drop. If you can disconnect your pump connections try it. Gently try to unscrew the intank pump and throw it - in Belgium you do NOT need it! Replace with just the intank filter, with anti-seize, and ONLY just tight enough to seal, with new rubber washer.

Luckily the thread of the in-tank pump was the same as the replacement filter screen : 37mm
Here some pics of my operation (no need to drop the tank) :
the sensor was still in good working state.
Only some rust at top but nothing bad
Here you can see that I have an in-tank pump
Support the tank and only remove the cradle
thread in the molded insert of the tank is in good state. No cracks
filter end of the in-tank pump is clogged with dirt
seal is completely gone
here you can see that pump is not working due to a cut in the supply wire. This would explain why my external pump did not supply sufficient fuel flow
nice replacement by a filter insert instead of an in-tank pump

Hi Allan,
Today I worked on the leak of my tank.

Glad our local beer matched your taste :-)
As soon as I have my 928 up and running, I will make some nice pics.
Meanwhile I only have the following pics :

today I managed to revive my 928 after mounting the WUR unit.
Warm control fuel pressure is now 3,4 bar and engine runs smoothly👍👌
Unfortunately I noticed another leak : coolant fluid under the thermostat housing😔
inside the hollow space under my thermostat, just above my waterpump...
Perhaps it was already there since some time because you barely notice this.
Strange because 3y ago I renewed all my seals of the thermostat housing inclusive the large O-ring
May small tear inside a tube? It sure is not my waterpump....
I heared that there are often troubles with the seals made of paper with rubber inserts.
