Thread: Td5 fuel pump or something else ?

Good info from everyone - however Eventhough you changed the pump it does not stop getting a clogged screen on the first stage of the pump.
Here is my pump after filling at an independent station somewhere in SE Queensland.20220331_155956.jpg
It is a great idea to fit a pressure gauge to monitor the regulated pressure when you are travelling - maybe a project for later. This swirl pot in which the pump body sits was full of dirt as well.
Not sure why - but my pressure gauge showed a steady pressure at the regulator at highway speed but only oscillated slightly from 4 bar during full power climbing hilly roads. My power was lacking from normal.
Car started fine with this amount of clogging and was audible but not noisy - starts faster with a new pump however.
I changed pumps because there was too much crud on the pickup screen and I couldnt clean them well enough. I fitted a new VDO pump which drew 10A KOEO on position 2 and is hardly audible. The current was measured across the relay pins - without relay in. The old pump drew a bit more but cant recall.
If there was air in the system it would probably sound like the highly audible fuel bleeding sound you hear on a purge cycle.

The attached picture in the post above shows how black the filter paper was - when I opened the filter.
Dirt recovered from the swirl pot is in this next image
